Publication number: 20230320263Abstract: A method for determining information, a remote terminal, and a mower are provided. The method includes: collecting a to-be-processed image for a to-be-recognized region through an image collector of a to-be-controlled device, where the to-be-recognized region at least includes a to-be-processed region and an obstacle region; processing the to-be-processed image, and determining information of a partial boundary of a to-be-processed region where the to-be-controlled device is currently located; and controlling the to-be-controlled device to switch between an autonomous movement mode and a remotely controlled movement mode based on the information of the partial boundary to determine a boundary of the to-be-processed region, where the boundary of the to-be-processed region is used for distinguishing the to-be-processed region from the obstacle region. The method can solve the problems of cumbersome operations and low efficiency existing in existing methods for determining a regional boundary.Type: ApplicationFiled: March 23, 2023Publication date: October 12, 2023Applicant: Willand (Beijing) Technology Co., LTD.Inventors: Zichong CHEN, Degan LIN, LV Zhuo, You WANG, Yue HU, Tianning YU, Chunhong LI, Shuai LI, Weijie TANG

Publication number: 20230286399Abstract: A charging station, a charging station system, a method and apparatus for returning to a charging station and a lawn mowing robot are provided. Feature markers are provided on the charging station, and the lawn mower can acquire pose information of the feature markers through its own image identification, so that relative pose information between the charging station and the lawn mower may be determined for path planning, enabling the lawn mower to realize station-returning and charging. The cost is low, and the structure is simple and easy to install and dismantle, since only the feature markers need to be provided on the charging station.Type: ApplicationFiled: March 8, 2023Publication date: September 14, 2023Applicant: Willand (Beijing) Technology Co., LTD.Inventors: Kai ZHOU, Xu YAN, Wanyang QIAO, Tianning YU
