Abstract—In reverse engineering practice, most designer will use 3D scanner to scan on 3D physical objects to obtain point cloud data, then the point cloud data is later being processed to obtain the final 3D CAD Model. However, when the 3D physical object is not at the same location as the 3D scanner, the 3D scanning method cannot be used. To overcome this limitation, another alternative computer method is proposed to obtain 3D point cloud from 2D image. This paper will further explain on the method on how to generate 3D point clouds without 3D scanner, hence enabling reverse engineering process to be done without using 3D scanner.
