Abstract

The present invention provides a method, device and storage medium for multi-camera detection of motion trajectory, wherein the method includes: setting a grid pattern on the ground, establishing a ground coordinate system; pasting an asymmetric pattern on the top of the robot, establishing a pattern coordinate system, and obtaining the angle The respective coordinates of the points in the pattern coordinate system; based on setting up multiple cameras above the ground to take photos of the grid pattern and the robot, each establishes a camera coordinate system, and obtains the respective pixel coordinates of the corner points of the asymmetric pattern in the camera coordinate system; obtains The first type homography matrix of each camera coordinate system relative to the ground coordinate system, the rotation amount and translation vector between the ground coordinate system, and the equation of the ground under the camera coordinate system; calculate the relationship between the pattern coordinate system and the ground coordinate system The rotation amount and translation vector of ; the second type of trajectory pattern of the robot is obtained by combining the images of each camera. The invention reduces the measurement deviation, improves the measurement accuracy, and the positioning range can be expanded infinitely.

Description

technical field [0001] The present invention relates to the field of detection of motion tracks, in particular to a method, device and storage medium for multi-camera detection of motion tracks. Background technique [0002] When the robot is moving, the requirements for trajectory accuracy are getting higher and higher. The robot trajectory accuracy has become an important indicator to measure the performance of the robot. Limited, the measurement deviation is large, and the measurement accuracy is easily disturbed by noise. [0003] Therefore, the present invention provides a method, device and storage medium for multi-camera detection of motion trajectories. Contents of the invention [0004] In view of the problems in the prior art, the object of the present invention is to provide a method, device and storage medium for multi-camera detection motion trajectory, to overcome the problem of limited measurement range and unstable measurement effect in robot motion trajec...
