摘要

PURPOSE: To recognize the existence and position of an object in the object space. ;CONSTITUTION: A camera 10 can be focused at multiple distances, and photographing is made at the depth of field of the focal point interval or below, for example. The image data corresponding to the focal point are temporarily stored in frame memories 13a-13g, and focal portions are edging-processed by image processors 14a-14g for individual focal points. The edging-processed image data are fed to a focal image generation section 16, and a synthetic image is generated. The presence and position of an object are grasped for space recognition based on the synthetic image in a space recognition section 17.;COPYRIGHT: (C)1995,JPO
