Patent number: 10067511Abstract: An automatic operation vehicle that automatically performs an operation in an operation area is provided. A survey unit acquires the position information of the marker using a first angle between the moving direction and a direction to the marker from a first point through which the vehicle passes during the movement in a constant moving direction, a second angle between the moving direction and a direction to the marker from a second different point through which the vehicle passes during the movement in the moving direction, and a distance between the first point and the second point. The survey unit determines the first point and/or the second point during the movement of the vehicle in the moving direction such that the angle difference between the first angle and the second angle becomes close to 90°.Type: GrantFiled: March 16, 2017Date of Patent: September 4, 2018Assignee: Honda Motor Co., Ltd.Inventors: Yasuyuki Shiromizu, Tsutomu Mizoroke, Makoto Yamanaka, Yoshihisa Hirose, Minami Kigami, Kensei Yamashita

Patent number: 10068141Abstract: An automatic operation vehicle that automatically performs an operation in an operation area is provided. The vehicle includes an image analysis unit configured to extract a marker included in an image captured by a camera provided on the automatic operation vehicle. If a situation in which the marker that was extracted from the image captured by the camera cannot be extracted by the image analysis unit from the image captured by the camera has occurred during a movement of the automatic operation vehicle in a constant direction. The image analysis unit determines whether the marker extracted before an occurrence of the situation and the marker extracted after an elimination of the situation are the same marker.Type: GrantFiled: March 16, 2017Date of Patent: September 4, 2018Assignee: Honda Motor Co., Ltd.Inventors: Yasuyuki Shiromizu, Tsutomu Mizoroke, Makoto Yamanaka, Yoshihisa Hirose, Minami Kigami, Kensei Yamashita

Patent number: 10054952Abstract: An automatic operation vehicle that automatically performs an operation in an operation area is provided. The vehicle includes a moving direction determination unit configured to determine a moving direction of the vehicle, an image analysis unit configured to extract a marker included in an image captured by a camera provided on the vehicle, and a survey unit configured to acquire, by triangulation, position information of the marker extracted by the image analysis unit. When the survey unit starts acquiring the position information of the marker, the moving direction determination unit determines, as the moving direction, a direction in which the vehicle does not come into contact with the marker, and an angle difference with respect to a direction from a current position of the vehicle to the marker is smaller than 90°.Type: GrantFiled: March 15, 2017Date of Patent: August 21, 2018Assignee: Honda Motor Co., Ltd.Inventors: Yasuyuki Shiromizu, Tsutomu Mizoroke, Makoto Yamanaka, Yoshihisa Hirose, Minami Kigami, Kensei Yamashita
