Abstract

The present invention relates to the field of robots, in particular to a method and device for a robot to follow a person, a storage medium, and a robot. The method includes: detecting a target person through a somatosensory detector installed on the robot, and obtaining the location of the target person in the original coordinate system. Under the relative coordinates relative to the robot; according to the first world coordinates of the robot in the world coordinate system, the relative coordinates are converted into the second world coordinates of the target character in the world coordinate system; according to the random expansion tree algorithm and The evaluation function based on the A* algorithm calculates and screens the intermediate nodes of the randomly expanded tree; when the distance between the intermediate nodes and the second world coordinates is within a preset range, the intermediate nodes are sequentially connected to form a target path, and the control of the The robot moves from the first world coordinate to the second world coordinate along the target path in a world coordinate system.

Description

technical field [0001] The invention relates to the field of robots, in particular to a method and device for a robot to follow a character, a storage medium, and a robot. Background technique [0002] With the gradual introduction of robots into the market, people began to pay attention to how service robots attract customers. Therefore, the research on how robots automatically follow people is constantly developing, and path planning is also an important direction of intelligent robot research. Robot automatic following includes target tracking and path planning. At present, target tracking uses methods based on object tracking or detection of pedestrian proportions to track pedestrians, but these methods have their own shortcomings. Among them, the method based on object tracking needs to be selected in advance. The object to be tracked can be tracked only when the object to be tracked is determined; the method of tracking based on the proportion of pedestrians is to dete...
