Patent number: 11500391Abstract: The present invention relates to a method for positioning on the basis of vision information and a robot implementing the method. The method for positioning on the basis of vision information, according to an embodiment of the present invention, comprises the steps of: generating, by a control unit of a robot, first vision information by using image information of an object sensed by controlling a vision sensing unit of a sensor module of the robot; generating, by the control unit of the robot, a vision-based candidate position by matching the first vision information with second vision information stored in a vision information storage unit of a map storage unit; and generating, by the control unit, the vision-based candidate position as the position information of the robot when there is one vision-based candidate position.Type: GrantFiled: May 14, 2018Date of Patent: November 15, 2022Assignee: LG ELECTRONICS INC.Inventors: Byungkon Sohn, Jungmin Shim, Kyuchun Choi

Publication number: 20220257074Abstract: A mobile robot of the present disclosure includes: a traveling unit configured to move a main body; a lidar sensor configured to acquire terrain information outside the main body; a camera sensor configured to acquire an image outside the main body; and a controller configured to fuse the image and a detection signal of the lidar sensor to select a front edge for the next movement and set a target location of the next movement at the front edge to perform mapping travelling. Therefore, in a situation where there is no map, the mobile robot can provide an accurate map with a minimum speed change when travelling while drawing the map.Type: ApplicationFiled: July 2, 2020Publication date: August 18, 2022Applicant: LG ELECTRONICS INC.Inventors: Jungmin SHIM, Jieun CHOI
