Application: Method and apparatus for controlling robot, electronic device, and computer-readable storage medium (Patent ID: US20230255429A1)
The patent filed by Gree Electric Appliances Inc of Zhuhai describes a method and apparatus for controlling a robot to clean right angle corner points in an environment. The method involves acquiring an environmental map of the current environment and detecting right angle corner points in the map. A coordinate system is determined for the corner points, and a target right angle corner point is selected based on certain preset conditions. The robot is then controlled to clean the target corner point.
The method for detecting the right angle corner points involves using a corner detection algorithm to process the environmental map and obtain a corner detection image. This image is then denoised to obtain a corner point denoising image. Piecewise linear fitting is performed on the corner points in the denoising image to identify the right angle corner points in the environmental map.
The determination of the target right angle corner point involves establishing a plane rectangular coordinate system using the coordinates of the corner points. Grayscale values of quadrants in the coordinate system are determined, and a target quadrant is selected based on a preset grayscale value. The target right angle corner point is then determined based on the number of target quadrants in the coordinate system.
Controlling the robot to clean the target right angle corner point involves acquiring position information of the target corner point in the environmental map. A target location is determined based on the position information and the shape parameter of the robot. The robot is then controlled to move to the target location and clean the corner point.
The patent also describes an electronic device that includes a processor, communication interface, memory, and a computer program for executing the method of controlling the robot. The electronic device performs the same steps as the method described above.
Overall, the patent presents a method and apparatus for effectively controlling a robot to clean right angle corner points in an environment, using corner detection algorithms, coordinate systems, and target selection based on preset conditions. The invention can be implemented in an electronic device with the necessary hardware and software components.
