Depth Sensors Support

iPi Recorder supports the following depth sensors:

Kinect 2 (Kinect for XBOX One)
Orbbec Astra (PRO)
Intel RealSense D415 and D435
ASUS Xtion 2
Microsoft Kinect for Windows
ASUS Xtion Live
ASUS Xtion
PrimeSense Carmine 1.08

First generation depth sensors are almost outdated but still usable. For example, Orbbec Astra (PRO) has totally the same depth quality and resolution as these outdated sensors. For this reason you can use for example MS Kinect v1 sensor(s) and get exactly the same results as with Orbbec Astra sensor(s). If needed you can find more information about these sensors in documentation for previous version of iPi Motion Capture.

As to modern depth sensors, MS Kinect 2 (Kinect for XBOX One) sensor remains the best choice for full body motion capture. The quality and accuracy of depth map from MS Kinect 2 are the best on the market.

Important! But only single MS Kinect 2 (Kinect for XBOX One) sensor can be connected to one PC due to limitation in Microsoft Kinect SDK 2. Each MS Kinect 2 (Kinect for XBOX One) sensor can be connected to a separate computer, Distributed Recording feature must be used.

Brief Comparison of Depth Sensors

Sensor Pros Cons
Kinect 2 (Kinect for XBOX One)
  • Higher FOV
  • Higher resolution of depth and RGB video
  • Lower noise, better quality and accuracy of point cloud
  • Higher overall tracking quality can be expected
  • Much better feet tracking
  • Low mutual sensors interference
  • More tolerant to lighting conditions
  • Has mount for tripod
  • Doesn't like shinning fabric
  • Requires USB 3.0 controller and external power supply
  • Only single sensor on one PC is supported by Microsoft Kinect SDK 2
  • Does not work on Windows 7 (requires Windows 8 and higher)
First-generation Depth Sensors
  • Ensures tracking quality comparable with Kinect 2, but hardware requirements are not so strong
  • Requires USB 2.0 controller
  • Multiple sensors can be plugged to single computer
  • Works on Windows 7 and higher
  • Lower FOV
  • Lower resolution
  • Lower accuracy
  • Less tolerant to lighting conditions
  • Higher mutual interference of sensors leads to more noise in case of using several sensors
  • No mount for tripod
Orbbec Astra (PRO)
See above (as first-generation depth sensors)
See above (as first-generation depth sensors)
Plus:
  • Higher price than price of first-gen sensors
  • Astra has mount for tripod but M6 instead of 1/4″

Technologies

Drivers

To use the sensors, you may need to download and install device drivers and software libraries for ASUS Xtion / ASUS Xtion Live / PrimeSense Carmine.
