Camera estimation doesn't work.

[MtKabu]

Using the camera, the estimation doesn't work.
Also, if "UseWebCam" in "ThreeDPoseScript" is set to true, the following error has occurred.

SetPixels32 called with invalid number of pixels in the array
UnityEngine.Texture2D:SetPixels32(Color32[])
ThreeDPoseScript:Update() (at Assets/Scenes/ThreeDPoseScript.cs:361)

I think that the error is the cause of the texture shift. How can I improve it?
