Paper Abstract

An approach to object recognition is discussed in which surfaces of objects in 3-D space are approximated by, pieces of spheres,cylinders and planes,and these pieces are recognized. This processing is realized by partitioning an image into regions and processing these regions in parallel. The purpose of this paper is to describe a technique which uses a recorded image of a camera with laser scanner to measure coordinates of 3-D surface points. The three of them in measured points in a region are then used to determine a plane and calculate further distances from feature points in the region to the plane. The multiple distance features can be used for recognizing whether the surface in a region is a piece of a sphere, a piece of a cylinder,or a piece of a plane. The surface orientations can be discribed by surface normal which has two oblique angles. This technique is useful for many purposes such as finding the three-dimensional positions and orientations of parts and calculating their surface shape properties which provide informations for industrial inspection.
