To increase the quality of the fusion algorithm in the Skeleton suite[1], a simultaneous recording via the Qualisys[2] allows us to test different fusion methods and compare ths result to the hig-quality one.
Setup
A 6 points kinect setup is used. The points are placed at the top of an hexagon.
Saliency map by Julien Leroy, press [SPACE] for RGB view.
Recording test
After 2 days of fine-tuning, meaning debugging the apps, adding the required functionalities and resolving the computers limitations, we are able to make a first complete test with 6 calibrated kinects.
Recording analysis
A skeleton seen by 2 kinects has been recorded.
Each message is time-stamped at emission (streamer[3] level) and also time-stamped at reception (recorder[4] level).
The recording is 16764 milliseconds long.
Remarks:
- Kinect SDK 2.0 is not time-consistent : the delta between 2 frames can go up to 67 milliseconds.
