Best settings for nuitrack.config for skeleton and face tracking with Intel D415

Nuitrack SDK
6

Please advise what is the distance between a tracked user and other people going behind him? If they’re too close, incorrect segment tracking is possible, which can lead to “merging” of skeletons.

You can try to restrict the processing range for depth data. To do this:

  1. open %NUITRACK_HOME%/data/nuitrack.config file in a text editor;
  2. add this line

"BoxCutter":{"x":"0","y":"0","z":"0","width":"1000","height":"4000","depth":"3000","alpha":"0","beta":"-1.5"},

as the first line to the “Segmentation” section.

Notes about 2nd step:

  • depth map will be thresholded by height/2 mm (depth values [0…height/2] will be processed only);
  • “beta” parameter is the BoxCutter’s rotation angle in radians along the X-axis of a sensor. So the box above should have the following dimensions after rotation: “width” x “depth” x “height/2” (X, Y, Z order here).
