ARCore Unity SDK - get access to the Frames for OpenCV

looking for a freelancer to create access to the frames in ARCore SDK in Unity.
Texture2d will not work so there are a few workarounds.
if you have experience with that then it will take you less then an hour and If you dont it will take you 3-4 hours.
Check RenderTexture -> ReadPixels and convert it back to Texture2D.
This is for Image processing and make an overlay data on the Surface of the ARCore environment.
