Patent number: 11607803Abstract: An object of the present invention is to ascertain parts of an object that are approachable by finger portions of a hand mechanism. In an image information processing device, a housing container is retrieved from an image by using a first retrieval frame, and an object is retrieved from the image by using a second retrieval frame. A plurality of determination points are set in advance on the second retrieval frame, and a predetermined approach direction is set for each determination point. A determination is then made as to whether or not the finger portions of the hand mechanism can be caused to approach parts of one object, existing within the second retrieval frame, that correspond respectively to the determination points set on the second retrieval frame from the predetermined approach directions set in relation to the determination points.Type: GrantFiled: October 4, 2019Date of Patent: March 21, 2023Assignee: THK CO., LTD.Inventors: Toshiya Watanabe, Yoshikazu Matsuo, Shinji Kawabata, Yoshimasa Endo, Kenji Hidaka, Daisuke Kawabata
