How do I get point cloud?

The key factor in acquiring point cloud data is the access/visibility to scanned surfaces. In most cases, point clouds are obtained by visible access to real objects. This means that simply to cover all scanning positions takes time. Aligning laser scans taken from all these scanning positions can also be a problem.
