Free ReconstructMe 2.4.1016 released

On behalf of the ReconstructMe team, I’m proud to announce ReconstructMe v2.4.1016. This update improves support for the following sensors

  • Intel RealSense F200
  • Intel RealSense R200

You can grab the latest version from our download page. We are releasing this version free of charge for non-commercial projects as announced recently.


To use Intel RealSense cameras on your computer you will need to install Intel RealSense camera drivers and use the correct ReconstructMe sensor configuration files. For your convenience, you can download both from below.

Once you have installed the necessary components, open ReconstructMe and set the path to the configuration file as shown in the screenshot below.



Please note that Intel recommends connecting the sensors to a dedicated USB3 port directly. Avoid using hubs or extension cables. When your sensor does not respond for longer period of time, restarting the Intel depth camera services might help. You can easily find these services in local services management console as shown below

ReconstructMe 2.4 brings color tracking

As promoted in our previous post we added a new color tracking feature to the SDK and promised to release a new UI frontend version supporting it. Today it is my pleasure on behalf of the ReconstructMe team to announce this new fronted release.

In the video below you can see ReconstructMe UI in action. Both scenes are tracked mainly due to color information, as the geometric information alone (planar shape in first scene and cylindrical shape in second scene) do not suffice to estimate the camera position accurately.

Color tracking is currently enabled for all sensors that support a RGB color stream. Algorithm settings are chosen automatically, so you don’t have to configure anything. In case your sensor does not support RGB the algorithm gently falls back to geometric tracking only. Note that scanning colorized is not a requirement for the color tracking algorithm to work properly.

Here are some tips for best results

  • Ensure that the scene you observe is texturally and/or geometrically rich. Although we’ve tuned the algorithm to cope with lack of information in both streams, we need at least some information to be present in the scene.
  • Try to get around 25-30 frames per second. Color tracking requires small increments in the transformation of the camera, otherwise it will not converge. Please note that the color tracking does more than geometric tracking alone, so it has a small increased runtime footprint.
  • Try to avoid fast camera motions that potentially blur color images.
  • Try to avoid reflective materials. Although a reflection appears as texture, it visually changes when moving the camera.

ReconstructMe SDK – Color Tracking Announcement

After weeks of hard work we are proud to announce a new upcoming feature called color tracking. Color tracking incorporates color information into camera motion estimation. This allows ReconstructMe to keep track over planar regions, cylindrical shapes or other primitive shapes. The following video shows some challenging reconstructions that succeed with the help of color tracking.

The new tracking algorithm seamlessly blends geometric and color information together, leading to an overall improved tracking performance in almost all situations. During development we’ve paid attention to robustness and runtime. As far as robustness is concerned, we’ve made sure that fast variations in illumination or camera auto exposure do not affect the tracking performance.

From a developer and user point of view you should be aware of the following points to maximize tracking stability.

  • Ensure that the scene you observe is texturally and/or geometrically rich. Although we’ve tuned the algorithm to cope with lack of information in both streams, we need at least some information to be present in the scene.
  • Try to get around 25-30 frames per second. Color tracking requires small increments in the transformation of the camera, otherwise it will not converge. Please note that the color tracking does more than geometric tracking alone, so it has a small increased runtime footprint.
  • Try to avoid fast camera motions that potentially blur color images.
  • Discard the first few camera frames as we have observed cameras to vary exposure vastly in these frames.
  • Make sure that the color camera is aligned to depth camera in space and time.

In case tracking fails we’ve also added a recovery strategy that takes color information into account. This global color tracking allows you to recover by bringing the sensor in a position that is close to the recovery position shown as shown in the following video.

Our roadmap forsees that we first release a new end user UI version that supports color tracking in the coming days. This will allow us to have many people test the current state of the algorithm and hence provide us with valuable feedback.

ReconstructMe 2.3.958 with Intel HD support

We continue to update ReconstructMe and are happy to announce our newest release supporting Intel HD 4000/4600 and Intel CPU Core i5/i7.

In case you intend to run ReconstructMe on a Intel HD graphics card, please update the graphics driver. If you favor running ReconstructMe on your Intel CPU install the latest OpenCL runtime.

Have fun reconstructing and let us know what you think!

ReconstructMe 2.3.954 released

We have just released new version of ReconstructMe. This is a bug-fix release that resolves immediate tracking lost issues on NVIDIA cards: our users reported immediate tracking-lost issues when starting a scan. The issue seems to occur on NVIDIA cards, with preference on the following models: GTX750, GTX970, GTX960, GTX840M, GTX850M. In case you are affected, please try to run the latest version.

ReconstructMe 2.3.952 released

We are happy to announce the release of ReconstructMe 2.3.952 today. The latest version can be downloaded here.

I’d like to briefly introduce the new SDK / UI features here and bring in-depth information in upcoming blog posts. The SDK / UI now supports the Intel RealSense F200 camera and we’ve reworked sensor positioning API to allow a more fine-grained control over the scan start position of the sensor with respect to the volume.

The UI now supports a rich set of sensor position options which include positioning the sensor based on a special marker seen by the sensor. This feature allows you to easily position the volume in world-space. The following video shows a turn-table reconstruction of a toy horse using marker positioning and the Intel RealSense F200 camera.

If you would like to try out the new Intel RealSense F200 camera, please download this sensor configuration file. You will need to specify the path to this file in the UI at Device / Sensor.

In case you want to give the marker positioning a try, please download this marker image, print it and measure the printed size in millimeters. Make sure to leave a big white border around the marker. You will need to set the correct marker size in the UI at Volume / Volume Position. We usually print the marker with size 90 millimeters. When using marker positioning, make sure the sensor captures the entire marker.

When you notice that the sensor position starts to vary as you move the marker, you know that ReconstructMe has detected the marker. Once ReconstructMe found the marker, you can use the Offset slider to adjust where the volume starts.

Enjoy and let us know what you think.

ReconstructMe selfies displayed on 3D screen

by Stefan Speiser

Hello everyone, my name is Stefan Speiser. I am a graduated Bachelor Student from the University of Applied Sciences (UAS) Technikum Wien in Vienna, Austria. I will present today my bachelor thesis in which I have worked with ReconstructMe.

The goal of the thesis was to create a booth for trade fairs and open days at the UAS Technikum Wien. At that booth a 3D-Scan of any willing visitor will be created, modified and then shown on a 3D-Monitor, so that the visitor can view him/herself in 3D. To reduce the needed time for the whole scanning-, modifying- and output process, a script capable of automating mentioned processes was created.
The booth was made as a marketing strategy of the UAS, in order to attract even more students than before by demonstrating how interesting technology can be.

This picture shows an early development stage of the booth with a functioning version of the script and all programs working as they should. On the left you can see the 3D-Monitor, next to it the control monitor where ReconstructMe runs and on the right is the Kinect System. Just barely visible on the bottom is a rotating chair.

Early development stage of the booth

To explain how I achieved this result, I would like to first write about the used hard- and software and afterwards explain the automationscript in detail.

Microsoft Kinect

To get the visual information needed for the 3D-Scan a Microsoft Kinect System was used. The person to be scanned sits in front of the Kinect System on a rotating chair. The built-in infrared projector emits a pattern of dots which covers the person standing in front of the Kinect Sensor and the rest of the room. These dots get recorded by the infrared camera and the Kinect System can calculate a depth image with this information.

An RGB camera recording at a resolution of 640×480 pixel and a frame rate of 30Hz grabs the color information of the scene in front of the Kinect System.

Both the depth image and color image information from the Kinect System is used by ReconstructMe. Since ReconstructMe offers native plug-and-play compatibility with the Kinect System, making scans was a breeze. The built-in 3D-Selfie function of ReconstructMe was the perfect fit for my project. It detects automatically when the person in front of the Kinect System rotates a full 360 degrees and stops recording the scan. During the processing phase, ReconstructMe stitches all holes in the mesh, shrinks the 3D-Scan and slices the upper body, so that if you would like to 3D-Print your scan, you could just save it and would be ready to 3D-Print it. (More information about the 3D-Selfie function can be found here:

Meshlab is an open source program which allows you to process and edit meshes. A mesh is collection of for example triangles which build a three-dimensional structure. Available is either the program version with a GUI or MeshlabServer. The special thing about MeshlabServer is the possibility to create a script with all the filters you would like to apply to your mesh and then start this script via the command console. For the sake of automation this approach is of course the favorable.

The filters used in my script are rotating and increasing the 3D-Scan from ReconstructMe to make it better visible on the 3D-Monitor and another filter is reducing the amount of triangles in the mesh by half. The quality reduction is almost not visible, but the file size and therefor the time needed to save the modified mesh is also reduced by half.





Tridelity MV5500 3D-Monitor

The modified 3D-Scan is shown to the visitor on an autostereoscopic 3D-Monitor. What is autostereoscopy you might ask? It’s a technology which enables the viewer to see a three-dimensional picture without the need for 3D-Glasses or similar equipment.

This effect is achieved with a parallax barrier, a barrier mounted in front of the LCD panel which only allows the viewer to see one picture for the left eye and one for the right eye. By chopping the 3D-Scan into small slightly shifted vertical lines, the brain stitches these pictures together and makes you see a 3D-View. This effect works best at a specified distance and since the monitor supports MultiView, up to 5 people can view the 3D-Scan at the same time from different angles. Depending on the angle to the monitor, the viewer sees the 3D-Scan more from the front or from the side.

AutoHotKey & Gulover´s Macro Creator

To automate keyboard entries and mouse clicks in the used programs, AutoHotKey was the tool of choice. It lets you automate every thinkable action in the Windows OS and every program running in it. It features IF/ELSE, Loops, a PictureSearch where you can search for a specific detail on the screen and if it’s found fire another function and many other tasks.

Gulover´s Macro Creator is a freeware program which offers a GUI for all functions and tasks of AutoHotKey. This makes working with and programming scripts in AutoHotKey much more time efficient and easier.
This was the description of the utilized hard- and software, now let me explain the automation script in detail.

The automationscript

The script first starts ReconstructMe and the Tridelity Software which loads the last saved 3D-Scan and outputs it on the 3D-Monitor. Then via PictureSearch ReconstructMe is scanned for an error message which appears when the Kinect Sensor is not recognized. If the error appears, the user is asked via a prompt to solve the problem with instructions given.

Next a 3D-Selfie scan is started and when finished the user and the visitor are asked if they like the result or if another scan should be started. If they are content, the scan gets saved and overwrites the last saved scan.
Now the visitor gets asked if he would like to save the scan in an extra folder. If this is wished for, the visitor gets to enter his name which is then saved with the current date added into a specific extra folder. The visitor could now copy the scan on an USB-Stick and take it home and modify it or directly print it with a 3D-Printer.

The scan is now getting modified by the Meshlab script running in MeshlabServer. After the filters are applied the now modified scan gets saved as a .obj file which in the next step can be opened by the Tridelity 3D-Monitor software. This software outputs the 3D-Scan and rotates it so that the visitor can view himself in all different angles. As you can see in the pictures, the 3D-Scan created in ReconstructMe is in color while the output on the 3D-Monitor is only in shades of grey. This is because the 3D-Monitor can only play back .obj files which are unable to store color information. ReconstructMe on the other hand offers four possible output file formats! (.ply, .stl, .obj, .mtl)

After a defined time the user gets asked if he would like to stop the script which would stop all running programs and then itself or if another scan is wanted in which case the script jumps back to the 3D-Scan routine and starts all over.

Thanks to a sponsored license for ReconstructMe which lowers the processing time after the completion of the scan by forty seconds, one complete pass of the script from the start of the 3D-Scan to the final output on the 3D-Monitor takes two minutes and twenty seconds. Definitely a time visitors are willing to wait and ask questions while their scan is being prepared for their viewing pleasure.

I would like to take this opportunity to once more thank the whole ReconstructMe Team, especially Mr. Rooker, and my UAF bachelor thesis supervisor FH-Prof. Dr. Kubinger for their support and valuable input.

ReconstructMe 2.2.940 Released

Today we are happy to announce a new release of ReconstructMe UI and ReconstructMe SDK. The new UI supports 64bit and supports saving OBJ with texture as outlined in our previous post. We’ve also made the surface scaling in Selfie 3D mode optional. The SDK release brings a couple of bug-fixes for x64 bit support and a better tuned texturing parameters.

Head over to downloads section to grab ReconstructMe.

ReconstructMe SDK with UV Texture Support and x64 Bit Support

Today we are happy to release an update for ReconstructMe SDK. The past couple of months we have worked hard on adding support for the two most requested features. One is that the new SDK now is able to export UV texture maps and the other improvment is 64bit support.

UV Texture Mapping

Previously, ReconstructMe was not able to export colorized meshes in .OBJ file format, due to the fact that this format does not support vertex colors. We have now adopted our pipeline to automatically convert from vertex colors to UV texture mapping when exporting as OBJ.

As simple as this may sound, this is not a trivial conversion and requires some hard thinking to get things right. The involved steps include unfolding complex 3D-dimensional shapes onto a 2D disc in such a way that minimal visual distortions appear plus rearranging individual portions of the unfolded structure in such a way that emptyness in the texture-space is avoided.

On the left side of the image above you can see a final textured mesh. The green lines indicate the texture seams, i.e the cuts that were made virtually to unfold the mesh to a disc like structure. On the right side the texture map is displayed.

We consider the current development progress beta. So when you use that feature expect some glitches, such as increased computation time and visual artefacts along texture seams.

x64 Bit Support

As promised we, from now on, release 32bit and 64bit versions of our SDK side by side. You should consider switching to the 64 bit version when processing huge models that come with a large memory footprint when processing them. The 64 bit allows the SDK to address more memory and complete the processing in such cases.

You can download the updated SDK here.

Scanoman – Open Source Portable Full Body Scanner

by Daniel Constantin

Scanoman ready for action

Scanoman ready for action

When I started the Scanoman project early this year, the following main requirements were considered:

  • Very affordable – for anyone who would like to have/build one;
  • Easily doable – by anyone who has minimal knowledge, experience and tools;
  • 3D printable – for as many parts as possible;
  • Lightweight and portable – so that one can take it here and there;
  • Simply usable – by anyone having some technical common sense.

At the time, there was (and still is) little information available about building a full body scanner in a DIY style. Therefore, I decided the design would have to become open source so that anyone could get inspired and make one.

Professional studios opted for multiple cameras taking snapshots of the subject from various angles and then compiling the data into a 3D model. This was obviously not an option for the project.

The hobbyist strategy was to use an inexpensive sensor, normally dedicated to game consoles, mount it on a pole, and have the subject being scanned when standing on a rotating turntable in front of the sensor.

The later appeared to be a reasonable approach for my purpose.

Microsoft Kinect for XBOX was the sensor of choice. It was the cheapest available and I could buy it from a general electronic equipment store, which very well complied with the requirements. I was aware that this would be at the cost of lower quality, since the senzor resolution and accuracy are very, very basic, but was a good starting point.

The long connection cable was an advantage. Since the sensor would have to go up and down on the pole, having a continuous cable was a plus.

The sensor is mounted on a slider that is driven by a NEMA 17 stepper motor through a reduction gearing, which pinion is running on a rack along the vertical pole. Using a rack was a simple way to solve the requirement of having the pole composed by individual segments, so it can be easily assembled and disassembled.

The sensor could also be tilted. I didn’t find a quick and easy way to use the internal motor of the senzor, so I used yet another stepper motor mounted on the slider. I discovered later on that you do not actually need too much this function.

The turntable construction required to solving many engineering issues.

After considering various alternatives, I went for the one that could be built from easy to find parts. It uses a round worktop that I found in the hardware store in 40, 60 and 80 cm diameter. I took the smallest one, which would suffice in most cases for single person scanning, and mount eight 626 bearings underside, so it could spin around a central axis. While each bearing would have to support more that 10 kg each, I placed a 1 mm steel sheet on top of the base plate (which is a 40 x 50 x 18 cm hard wood board).

The most challenging part was to drive the turntable. After many trials, I came to the optimal configuration in respect to speed, power and… cost. Using a simple NEMA 17 stepper motor, a reduction gearing and a 300-tooth “circular rack” was enough to obtain a full rotation of an 160 kg load in 20 seconds!

Having the sensor sliding along a 2.5 m height pole made from aluminum square tube (this was easier to found and cheaper than T-slot bars), cut in 5 segments, and the turntable easily rotating with one person standing on it have solved most of the construction issues.

A second hard wood board was used to mount the pole, the power supply, the controller, an USB hub and all the mountings used to hold parts of the scanner while disassembled.

Scanoman uses a controller designed for 3D printers, as it has to drive 3 stepper motors, sense 2 endstops, and also turn on and off the supplementary spotlights. And software-wise, it is controlled through the very well known (in the 3D printing reprap world) application called Pronterface. This was once again a proof that 3D scanning and 3D printing go hand in hand!

Scanoman packed and ready to go

Scanoman packed and ready to go

As intended, Scanoman is portable.

It could be easily (dis)assembled in a quarter of an hour, using just a small screwdriver to fix the pole segments.

I have to admit that this version is not so light as I would liked too, weighting some 15 kg! Good news is that I identified means by which the total weight could be reduced by half!

Scanoman already traveled in Bucharest and is expecting more opportunities to do his job, which is, no wonder, to scan people. While some people might be happy to come to a scanning studio, others will prefer to being scanned at home. Or you can take it with you when going to a party and scan the participants!

When it came to 3D scanning software the choice was not less than obvious: ReconstructMe!

It is by far the most user-friendly, rapidly evolving and almost free 3D scanning application.

ReMe does the job very well and fast. And it’s also fashionable. Want to have a 3D selfie? Nothing simpler, you get a ready to be printed bust model of yourself, at a click of the mouse (well, with Scanoman is really as such!)

3D scanning becomes a very very simple task. Perhaps the only single thing you have to carefully consider is lighting. You should have a uniform and indirect lighting of the subject, of adequate white tone and intensity, or you can easily get artifacts on your model (this may explain why Vali, my wife, does not seem to be vary happy in her 3D selfie).

Scanoman and Vali saying bye-bye

Scanoman and Vali saying bye-bye

And, yes, you need a more than decent computer, but not necessarily a top edge one. I’m using an Acer Aspire V3 which works very well and its price tag is well below 1000 EUR.

When it comes to money, if we put aside the sensor, Scanoman cost would be below 250 EUR, including all materials, electronics, motors, etc. Well, it will take some time to build one, but this is fun, lots of fun! And, as promised, Scanoman is open source.

Coming up next is a new version of Scanoman. It will focus on optimizing the construction, reducing weight and improving usage. Then more thoughts should be given to performance and quality.

You may want to keep an eye on that, by following 3Dmaker4U on the websiteFacebookYouTubeor LinkedIn.

3Dmaker4U is an initiative that is aimed to promoting and developing 3D technologies, such as 3D printing, 3D scanning and 3D modelling, and their applications.

Bye-bye for now and enjoy the short Scanoman introductory video below!

ReconstructMe Handheld Scanning

Right before the holiday season in Austria kicks off, we wanted to share with you one of our latest developments, called ReconstructMe Mobile Scanning. It’s all about turning ReconstructMe into a handheld scanning device, removing long USB cables and creating the freedom of scanning without limitations.

In the video below you can see me scanning a bust using a Windows Tablet connected to an ASUS Xtion pro live using a custom 3D printed mounting.

We needed to adapt ReconstructMe so you can scan using low-powered mobile devices such as Tablets. The approach we took is illustrated below.

The required hardware consists of a background desktop PC or notebook and a lightweight Tablet that is connected to a 3D sensor. The actual reconstruction is performed on the PC in background. This workhorse receives the compressed 3D data from the Tablet via WiFi and computes a 3D model in real-time. The current state of reconstruction is sent back to the Tablet PC for visualization. An additional communication channel is used for transmitting commands from user interaction. This setup allows use to scan with 30 frames per second.

In case you are interested in a close-up of the sensor mounted to Tablet, here is a short clip of those.

Holiday season

Please note that our shop will be closed from 22nd of December until 5th of January 2015. The ReconstructMe team wishes all users and friends happy holidays! We are looking forward to see you next year.
