Unity sample of 3D pose estimation using Barracuda


ThreeDPoseUnityBarracuda is a sample source which read the onnx by Barracuda and do threeD pose estimation on Unity. the accuracy got better than pre model.
*Be aware of that the target should be only one person. It does not work for multi target.

This sample lets the avatar named as “Unity chan” behaves same as the man on real time by estimating the 3D positions on the movie.


Created with Unity ver 2019.2.12f1.
We use Barracuda 0.4 to load onnx.
By updating the version to 0.5, it seems like the speed get slower.
Now we are still trying 0.5 version.
