Please help me with 3D study.

[itsgoodforyou2]

Hello. I'm a beginner in 3D. What I want to make is Vision-Guided Robot software.

I would appreciate it if you could let me know if there is anything I need to study to solve the two questions below.

Questions.

1. I want to know how to cut only certain objects from point cloud images acquired with vision cameras, and set the origin.

2. I want to know how to get the location value of the object by exploring the object I want to find in the point cloud image acquired with the vision camera.

Thank you.
