I just get a piece of "point cloud" after running process_exr.py,what happened?

I also use the code [process_exr.py] and [render_depth.py] to produce pcd file.
it is not like a part model of point cloud model, but just like a picture in a zoom.

It may be used to project part of the point cloud to be used as a training set
