What sensor should I buy?
Each sensor has its pro and cons. If you are an occasional user on a budget, and do not plan to scan for commercial applications then Kinect for Xbox is the cheapest alternative. Kinect for Windows has better driver support, can be used for commercial applications and has a growing list of additional features (gain control, near mode, etc.). If you don’t need a motor and would like a device without external power supply, then the Asus Xtio Pro Live or Primesense Carmine 08 is a good alternative. For close range applications (35cm – 2 meters), the Primesense Carmine 09 is the best choice, with lower minimal distance and more precision.
My Kinect for XBox sensor cannot be detected!
The Kinect for Windows drivers are known to interfere with Kinect for Xbox. Make sure you uninstall Microsoft drivers, and then reinstall OpenNI drivers.
Also, make sure you are plugging it to a USB 2.0 port, there are some known issues with USB 3.0.
What are the different scene types?
We have defined a number of presets that we have found to work best for different kind of scenes. Currently you can choose between 5 different scanning modes:
- Body: This is the ideal setup to scan the bust of a person, with a bounding box of more of less 1x1x1m. You can increase the bounding box size to scan the whole body. It also performs well for mid-sized furniture.
- Object: This mode is best for smaller objects, with a default bounding box of 0.6×0.6×0.6m. It can capture finer details, at the risk of loosing camera tracking more easily.
- Room: This mode is designed to capture a 360º small room. The initial sensor position will be it the center of the bounding box.
- Half Room: This mode is better for scanning only a part of a room, with an initial sensor position near the back of the bounding box.
Why does the camera keep losing track?
If you are using the GPU reconstruction, then the following tricks can help:
- Avoid flat walls and empty regions during the scan. Make sure you include part of the floor or some furniture to keep the tracking precise and stable.
- When scanning small objects, using a turntable and keeping the camera fixed is usually better.
- Also, if the object to be scanned is small or has few geometry, you can help the tracking by adding other objects around it. You will be able to crop the object of interest afterwards.
Also, make sure you move slowly and smoothly during the scan. Big gaps between frames can lead to tracking failure. If your FPS is too low (e.g. < 10 FPS), then you should probably consider getting a better graphics card.
What graphics cards are supported?
In general, any NVidia graphics card with more than 1Gb or memory and compatible with CUDA 2.0 should work. However, to ensure a good framerate, the GTX serie is highly recommended, both for laptop and desktop configurations.
We develop Skanect using an Asus laptop with a GTX 560M, an Alienware laptop with a GTX 580M, and an Alienware X51 desktop with a GTX 660.
My GPU should be supported, but GPU fusion is disabled, why?
Make sure you have the latest NVidia drivers for your graphics card. If it does not solve the issue, please send us your log file (Settings / Open log file).
