With "pcregistericp" it is possible to localize a small PointCloud cropped from large one. It seems that ICP algorithm uses Locations and denies Color vectors. Correct me if I'm wrong.

But when I use a cloud from just another scan and try to localize it in large cloud, it not works correctly.

Hi,
pcregistericp returns the transformation between the point clouds.
To find the location of an object in the point cloud, first step is to segment out the object in the point which altogether a different problem and dependent of the type of the object. Functions like pcfitplane, pcfitshpere, and pcfitcylinder help in detecting object of shapes such as plane, sphere, or cylinder respectively.
Also have a look at the following example which segments and tracks the vehicle from the lidar point cloud, few functionalities can be useful for your purpose .
Hope this helps
