If you need real-time tracking and want to track the skeleton, these options may be best for you.
1. The super-powerful new D435 RealSense camera model that goes on sale January 8.
2. Combining the camera's 'RealSense SDK 2.0' software with a skeleton tracking module in the OpenCV software platform, which SDK 2.0 is compatible with.
OpenCV skeleton tracking:
1. What the camera will be able to do with skeleton tracking depends on the OpenCV module used with it. If an OpenCV module can support lower body tracking, then the D435 should be able to use that software with OpenCV to track those points.
2. The D435 can output depth streams at up to 90 Frames Per Second (FPS), a significant improvement on previous RealSense cameras that were limited to a maximum of 60 FPS.
3. Any time that you add additional actively processing devices to a PC, it is going to consume more of that PC's resources such as CPU load and memory usage. This may have an effect on RealSense data processing, as once the camera sends data through the USB cable to the PC then it may encounter a processing bottleneck, depending on what programs are running on the PC and the capabilities of its hardware
