Abstract

Classical machine vision is difficult to be used as practical 3D vision because it loses depth when projecting 3D objects into 2D images and then has ambiguity when reconstructing 3D object. In contrast, range images, i.e. 3D images, keep the invariance properties of 3D objects, which makes the image processing tasks easier. This paper develops the prototype of spatial encoder using laser scanning method. Range images are obtained based on encoded images produced by our encoder.
