A robot visual tracking method and system thereof

Abstract

The present invention proposes a method for visual tracking of a robot. The method includes: tracking a target frame selection, establishing a coordinate position (x 0 ,y 0 ); target center point prediction, in the next frame of image, the position of the tracking target in the coordinate system is calculated by motion prediction, the maximum width of the image is R, the maximum height is C, and the target center in the x-coordinate direction (width direction) of the nth frame is set The coordinates are x(n), and the coordinate position in the y direction (height direction) is y(n). According to the movement of the target in the x direction and the y direction, a displacement command is generated, and the robot or the camera is notified to move according to the corresponding displacement; the robot vision tracking method of the present invention has fast running speed and good tracking effect, does not rely on any third-party library, and is portable It has strong performance and can run on ordinary processors. As a result, products in the fields of robots and other fields can greatly reduce the cost of the platform.

Description

technical field [0001] The invention relates to the technical field of image processing and image recognition, and in particular to a robot visual tracking method and system thereof. Background technique [0002] At present, artificial intelligence algorithms, especially computer vision algorithms, are developing faster and faster, and are gradually being applied in many industries and fields. Taking visual tracking as an example, there is a great demand for applications in the fields of robot navigation, automatic driving, and intelligent security. However, for the visual tracking algorithm, whether it is a traditional visual tracking algorithm or an emerging computer vision algorithm based on deep learning, the calculation amount of the algorithm is very large, and the GPU or FPGA processor array is usually used for calculation, which affects the performance of the processor. The requirements are relatively high. For some general intelligent requirements, especially for ...
