Paper Abstract

The analytic method of variable density image is generally used to recognize the shape of an object by visual processing. On the other hand, by using the data of the distance from the object, the accurate sampling of the shape which is independent of the contrast between objects and others is realized and the shape recognition is simplified. Therefore, the effective method for measuring a distance is required in fields of computer aided design and automatic measurement. Recently, the measurement of a distance using the principle of triangulation and the laser beam has been put to practical use. 1)
