Patent number: 11822341Abstract: Provided are a control device, a control method, and a mobile object that enable distinction among positions and accurate estimation of a self-position even in an environment where different positions include many similar feature amounts in surroundings and are thus likely to be erroneously detected as being the same position. In accordance with a place corresponding to the self-position, an image feature amount is extracted from an image of surroundings to which a mask has been added on the basis of a place-related non-feature portion representing an area, in the image of the surroundings, that is not useful for identifying the self-position, and the image feature amount and positional information regarding the self-position are associated with each other and registered in a position/image feature amount database (DB).Type: GrantFiled: December 14, 2018Date of Patent: November 21, 2023Assignee: SONY CORPORATIONInventors: Dai Kobayashi, Ryo Watanabe

Patent number: 11592829Abstract: A control device and a control method can quickly estimate a self-location even when the self-location is unknown. In a case of storing information supplied in a time series detected by LIDAR or a wheel encoder and estimating a self-location by using the stored time-series information, when a position change happens unpredictably in advance such as a kidnap state is detected, the stored time-series information is reset, and then the self-location is estimated again. Example host platforms include a multi-legged robot, a flying object, and an in-vehicle system that autonomously moves in accordance with a mounted computing machine.Type: GrantFiled: November 21, 2018Date of Patent: February 28, 2023Assignee: SONY CORPORATIONInventors: Dai Kobayashi, Ryo Watanabe

Patent number: 11500386Abstract: An action plan is generated even when the own position is unknown in order to move autonomously. A route is planned for each position constituting an own-position candidate on the basis of status of surroundings. Multiple candidates of an action plan constituting multiple action candidates are generated on the basis of the planned routes. An evaluation value is set to each of the generated multiple action plan candidates. The action plan is determined using the action plan candidates in accordance with their evaluation values. This technology is applied advantageously to multi-legged robots, flying objects, and onboard systems each controlled by an onboard computer to move autonomously.Type: GrantFiled: September 4, 2018Date of Patent: November 15, 2022Assignee: Sony CorporationInventors: Dai Kobayashi, Takamori Yamaguchi, Ryo Watanabe

Publication number: 20220309698Abstract: Provided is a self-position estimation mechanism that can absorb the influence of resetting of a position estimator. A difference between a position for each epoch and a position of a previous epoch estimated by a first estimation unit using a camera image and IMU information and a velocity and an acceleration for each epoch estimated by a second estimation unit using the camera image and the IMU information are acquired. Whether the difference acquired for each epoch is an outlier is tested on the basis of a threshold and whether the velocity and acceleration acquired for each epoch is an outlier is tested on the basis of a threshold. A self-position is estimated using the difference for each epoch and the velocity and acceleration for each epoch after the outlier is removed.Type: ApplicationFiled: July 1, 2020Publication date: September 29, 2022Inventors: YUSUKE TAKAHASHI, DAI KOBAYASHI, RYO WATANABE, MASATAKA TOYOURA
