I've been trying to get person joint tracking to work with R200 camera. I've been able to get as many as 6 joint points only recognized.
1. Am I getting only 6 joint points because of R200 capability or because of my code?
2. Is skeleton (person joint) tracking supported with new SDK 2.0, therefore should I get new camera?
3. Which approach should I take to track full body for joints? (Is RealSense good enough?)
Skeleton tracking on the old RealSense cameras has limited functionality, and often does not work at all. This is because it was a Preview level feature, considered earlier than even the very basic Alpha level of development progress. So it never received much development beyond its initial release. The limitations are in the software, not in your code.
An advanced new skeletal tracking solution called Nuitrack was recently made available for the 400 Series cameras.
