Kinect SDK에 대하여 찾던 중 OpenNI라는 것을 알게 되었다.
MS에서 공개한 SDK 베타버전과 OpenNI에 대한 비교는 다음과 같다.

둘다 각각 장단점이 존재 한다.
Kinect SDK와 OpenNI를 연동시키는 것도 존재한다고 하니 좀 더 찾아봐야 겠다.

Microsoft’s Kinect SDK (Beta)
pro:

  • support for audio
  • support for motor/tilt
  • full body tracking:
    • does not need a calibration pose
    • includes head, hands, feet, clavicles
    • seems to deal better with occluded joints
  • supports multiple sensors
  • single no-fuss installer
  • SDK has events for when a new Video or new Depth frame is available

con:

  • licensed for non-commercial use only
  • only tracks full body (no mode for hand only tracking)
  • does not offer alignment of the color&depth image streams to one another yet
    • although there are features to align individual coordinates
    • and there are hints that support may come later
  • full body tracking:
    • only calculates positions for the joints, not rotations
    • only tracks the full body, no upperbody or hands only mode
    • seems to consume more CPU power than OpenNI/NITE (not properly benchmarked)
  • no gesture recognition system
  • no support for the PrimeSense and the ASUS WAVI Xtion sensors? (can anyone confirm this?)
  • only supports Win7 (x86 & x64)
  • no support for Unity3D game engine
  • no built in support for record/playback to disk
  • no support to stream the raw InfraRed video data
  • SDK does not have events for when new user enters frame, leaves frame etc

 

PrimeSense OpenNI/NITE

pro:

  • license includes commercial use
  • includes a framework for hand tracking
  • includes a framework for hand gesture recognition
  • can automatically align the depth image stream to the color image
  • full body tracking:
    • also calculates rotations for the joints
    • support for hands only mode
    • seems to consume less CPU power than Microsoft Kinect SDK’s tracker (not properly benchmarked)
  • also supports the Primesense and the ASUS WAVI Xtion sensors
  • supports multiple sensors although setup and enumeration is a bit quirky
  • supports Windows (including Vista&XP), Linux and Mac OSX
  • comes with code for full support in Unity3D game engine
  • support for record/playback to/from disk
  • support to stream the raw InfraRed video data
  • SDK has events for when new User enters frame, leaves frame etc

con:

  • no support for audio
  • no support for motor/tilt (although you can simultaneously use the CL-NUI motor drivers)
  • full body tracking:
    • lacks rotations for the head, hands, feet, clavicles
    • needs a calibration pose to start tracking (although it can be saved/loaded to/from disk for reuse)
    • occluded joints are not estimated
  • supports multiple sensors although setup and enumeration is a bit quirky
  • three separate installers and a NITE license string (although the process can be automated with my auto driver installer)
  • SDK does not have events for when new Video or new Depth frames is available
