Hi, I was trying to convert the unorganised RGB pointcloud provided by Intel Realsense D435 into a 2D image. I got the intrinsic parameter from the realsense-viewer software. But not sure what is the meaning of Fx & Fy. I guess that PPx and PPy must the principle offset. If Fx & Fy are the focal length in x & y direction respectively, what is the focal length in meters. I think that the intrinsic parameters are in pixel values. Can you suggest me a way to figure out the pixel size in meters. Please correct me if I had misunderstood anything.

Hi, Actually I found the answer to my question here.

Fx, Fy - Focal lenght. PPx, PPy - Principle point (Center of Projection).
