The Depth Map Construction from a 3D Point Cloud

Abstract

A depth map transforms 3D points into a 2D image and gives a different view of an observed scene. This paper deals with a depth map construction. It describes the whole process, how to transform any 3D point cloud into a 2D depth map. The described method uses 3D rotation matrixes and the line equation. This process allows to create the desired view from arbitrary point and rotation in an exploration space. Using of a depth map allows to apply image processing methods on depth data to get additional information about an ambient space.
