[Kinect] Microsoft Kinect SDK vs PrimeSense OpenNI

출처 : http://www.brekel.com/?page_id=671

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
