Patent number: 11373416Abstract: An image processing device includes: a detection unit which detects a target object based on edge information acquired from image data; and a judging unit which judges whether a certain region in the image data is an improper region that is not suitable for detection of the target object based on an edge pattern of edge information in the certain region and a feature pattern indicating a feature of the target object, and the detection unit detects the target object excluding a region that has been judged to be the improper region by the judging unit.Type: GrantFiled: September 18, 2019Date of Patent: June 28, 2022Assignee: DENSO TEN LimitedInventors: Yasutaka Okada, Hiroaki Sano, Tetsuo Yamamoto, Atsushi Yoshihara, Jun Kanetake, Ryo Yoshimura, Tomoki Shidori

Patent number: 11256933Abstract: An image processing device includes: a delimiting line detection unit configured to detect a delimiting line candidate based on image data obtained by capturing a surrounding of a vehicle; an exclusion determination unit configured to determine whether there is a parking-unavailable area in which parking of the vehicle is not permitted; and a parking space detection unit configured to detect the parking space based on the delimiting line candidate. In a case where plural parallel lines that are adjacent to the delimiting line candidate and that have a predetermined angle to the delimiting line candidate is detected, the exclusion determination unit regards an area in which the plural parallel lines are provided as the parking-unavailable area, and prohibits the parking space detection unit from detecting the parking space across the delimiting line candidate adjacent to the parking-unavailable area.Type: GrantFiled: September 18, 2019Date of Patent: February 22, 2022Assignee: DENSO TEN LimitedInventors: Yasutaka Okada, Hiroaki Sano, Tetsuo Yamamoto, Atsushi Yoshihara, Jun Kanetake, Ryo Yoshimura, Tomoki Shidori
