Generation of 3-D Models Based on Image Fusion of Range Data

This paper presents a method for measuringthe entire three dimensional (3D) shape of object, which is applicable for 3D digitizing into a solid modeling CAD. The method measures the complete surface model of the object automatically and in the non-contact way. The method employs two range finders and a turn-table cooperatively:a fixed range finder using a turn table measures rough surface data of the objects, and a hand-eye range finder finds the deficit of surface data due to self occlusion and makes it up by changingto it. The 3D shapeis represented in an extended octree in computer. The octree representation allows us to keep more precise shape in smaller memory storage. An experimental system based on the method shows us the good flexibilityand performance of the method for 3D digitizing.
