This paper describes about a shape data acquisition system in which a vision and a new type of proximity sensor are integrated for the detection of various 3-D data required in handling tasks by robot. The vision sensor is used for acquiring the entire image of objects over the working area and extracting the edge image which is used to positioning the proximity sensor to the interesting area on the 3-D object. The proximity sensor detects the range data and also extracts the jump edges of the surface in the interesting area. In the developed proximity sensor, a ring beam pattern which is generated by passing a laser beam through a cone lens, is projected onto an object; range data are detected from the position of the objective lens where the ring beam pattern is focussed to a point. The position and the direction of a jump edge are estimated by analyzing the image of a ring beam pattern projected on the jump edge. To confirm the basic principle of the system, experiment is carried out on the surface of the regular icosahedron.
