Interaction with wall using skeleton tracking

[olga.kuzminykh]

Hi Timur,

Background calibration can help to solve such problems but it’s not a perfect solution for RealSense D415. The recommended distance between this sensor and a user for this sensor is about 1-1.5 meters. Skeleton tracking at greater distances can be unstable.

Skeleton tracking quality depends on the quality of a depth map. If possible, you can try to use other sensors (such as Orbbec Astra/Astra Pro or ASUS Xtion), which provide good quality of a depth map.

You can also try to use post-processing filters with D415 to improve the tracking quality. To do this, you have to edit nuitrack.config:

Starting from Nuitrack 0.23.1, two post-processing filters are available using nuitrack.config file: in the Realsense2Module section, you can find the SpatialFilter and DownsampleFactor (corresponds to the decimation filter in RealSense SDK). For example, if you set DownsampleFactor to 2, the noise level in the depth map will be reduced according to the Intel recommendations.

Also please try to run any standard sample (for example, nuitrack_sample) to check background calibration. Do you get the same result?
