RealSense CHOP

Summary

The RealSense CHOP references a RealSense TOP camera and fetches tracking data from it. The RealSense CHOP supports skeleton tracking through the Cubemos Skeleton Tracking API. It is Windows only. A Cubemos license is required to use the skeleton tracking.

Skeleton Tracking Setup

The RealSense CHOP supports skeleton tracking through the Cubemos RealSense Skeleton Tracking API. The Cubemos API requires a license to use in TouchDesigner. A full license can be purchased here; a trial license is also available. Installing their SDK is required to setup the license file. After installation of the SDK, the license can be setup with the post_installation.bat script in the C:/Program Files/Cubemos/SkeletonTracking/scripts folder. A model file (.cubemos) is also required for the skeleton tracking, two of which are packaged with the Cubemos Skeleton Tracking SDK, located in their Cubemos/SkeletonTracking/models/skeleton-tracking folder.

Parameters - Setup Page

Active active - When enabled, actively fetches skeleton tracking data from a RealSense TOP.

RealSense TOP top - The RealSense TOP camera to fetch skeleton data from.

Skeletons skeletons - When enabled, displays the skeleton channels.

Max Players maxplayers - Specify the max number of players tracked.

Image Position Pixels pos - When enabled, will display positions of each landmark in image pixels as x/y channels.

Image Positions Normalized norm - When enabled, will display normalized position values of each landmark as u/v channels.

Confidence confidence - When enabled, will display the confidence value of each landmark. When the confidence channel value is 0 the landmark is untracked.


Parameters - Common Page

Time Slice timeslice - Turning this on forces the channels to be "Time Sliced". A Time Slice is the time between the last cook frame and the current cook frame.

Scope scope - To determine which channels get affected, some CHOPs use a Scope string on the Common page.

Sample Rate Match srselect - - Handle cases where multiple input CHOPs' sample rates are different. When Resampling occurs, the curves are interpolated according to the Interpolation Method Option, or "Linear" if the Interpolate Options are not available.

  • Resample At First Input's Rate first - Use rate of first input to resample others.
  • Resample At Maximum Rate max - Resample to the highest sample rate.
  • Resample At Minimum Rate min - Resample to the lowest sample rate.
  • Error If Rates Differ err - Doesn't accept conflicting sample rates.

Export Method exportmethod - - This will determine how to connect the CHOP channel to the parameter. Refer to the Export article for more information.

  • DAT Table by Index datindex - Uses the docked DAT table and references the channel via the index of the channel in the CHOP.
  • DAT Table by Name datname - Uses the docked DAT table and references the channel via the name of the channel in the CHOP.
  • Channel Name is Path:Parameter autoname - The channel is the full destination of where to export to, such has geo1/transform1:tx.

Export Root autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is Path:Parameter are relative to.

Export Table exporttable - The DAT used to hold the export information when using the DAT Table Export Methods (See above).
