how to obtain points for pointcloud registeration of images

I have images of an object. How do I get the point cloud from the image to do point cloud registeration using CPD algorithm. Do I need any hardware like LIDAR or can you get the points just using code. Also, are there any reference documents for Pointcloud Registration using Coherent Point Drift (CPD). Thank you,

Hi,

The method of converting multiple 2D images into a 3D scene is known as Stereo vision. You can refer to the following documentation to get started.

For Point cloud registration, you will be needing two actual point clouds which can be collected from a LiDAR sensor. Point cloud registration using Coherent Point Drift is available as a separate function pcregistercpd. For other point cloud registration techniques and workflows you may refer to the following documentation.

Hope this helps to get started!
