摘要: An apparatus for recognizing an object may include a lens, camera and signal-processing unit. The lens two cross sections having different focal lengths. be configured to photograph the first part through lens. have shape. unit recognize height of based on deviations shape in image obtained from camera. Thus, only cylindrical interposed between except softwares processing signals. As result, simple structure without laser irradiation.
