Embodiment 1

[0070] see figure 1 , the control method of the visual navigation robot of the embodiment of the present invention, the visual navigation robot includes a positioning module, and the control method of the visual navigation robot includes the steps:

[0071] S01: Obtain the light intensity of the current environment;

[0072] S02: When the light intensity is less than the preset threshold, obtain the positioning error corresponding to the positioning module;

[0073] S03: Determine the safe distance between the visual navigation robot and the boundary line according to the positioning error;

[0074] S04: Obtain the position information of the visual navigation robot;

[0075] S05: When the distance between the vision-guided robot and the boundary line is less than or equal to the safety distance, control the vision-navigation robot to change the moving direction so that the distance between the vision-navigation robot and the boundary line is greater than the safety distance...

Embodiment 2

[0089] see figure 2 , further, step S02 includes the steps of:

[0090] S021: Obtain the type of the positioning module;

[0091] S022: Obtain a positioning error according to the type of the positioning module.

[0092] In the case of different types of positioning modules, the positioning methods are also different, and in the case of different positioning methods, the positioning errors are also different. In this embodiment, the visual navigation robot can Different types of positioning errors are obtained, so that the safety distance determined by the visual navigation robot according to the positioning error is more accurate.

[0093] In this embodiment, when the light intensity of the current environment acquired by the visual navigation robot is greater than a preset threshold, the positioning module may not work. When the light intensity of the current environment acquired by the visual navigation robot is less than the preset threshold, the positioning module sta...

Embodiment 3

[0107] see image 3 , further, the control method of the visual navigation robot also includes steps:

[0108] S06: Obtain the boundary line and the boundary type of the boundary line in the working area map of the visual navigation robot, where the boundary type includes a safe boundary and a dangerous boundary;

[0109] Also include steps before step S05:

[0110] S051: When the distance between the visual navigation robot and the boundary line is less than or equal to the safety distance, obtain the boundary type of the boundary line;

[0111] S052: When the boundary type of the boundary line is a dangerous boundary, execute and control the visual navigation robot to change the moving direction so that the distance between the visual navigation robot and the boundary line is greater than the safety distance.

[0112] Wherein, the above-mentioned working area map may be map information obtained after manual walking, or map information obtained through images c...

Abstract

The invention is suitable for the field of robot processing, and provides a visual navigation robot control method and device, and a computer readable storage medium. The control method of the visualnavigation robot comprises the following steps: obtaining the illumination intensity of a current environment; when the illumination intensity is smaller than a preset threshold value, obtaining a positioning error corresponding to a positioning module; determining a safe distance between the visual navigation robot and a boundary line according to the positioning error; acquiring position information of the visual navigation robot; and when the distance between the visual navigation robot and the boundary line is smaller than or equal to the safe distance, controlling the visual navigation robot to change the moving direction to make the distance between the visual navigation robot and the boundary line larger than the safe distance. The visual navigation robot can be automatically far away from a dangerous area and is not influenced by light of the environment, and the safety performance of the visual navigation robot is improved.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a control method, device and computer-readable storage medium of a visual navigation robot. Background technique [0002] The visual navigation robot captures images of the surrounding environment through the camera, and then calculates and analyzes based on the captured images, so that the visual navigation robot can move according to the desired path, so as to avoid the visual navigation robot from entering the dangerous area. In the prior art, when the visual navigation robot works in an environment with weak light (such as cloudy days and nights), the visual navigation robot supplements the light by turning on its own lighting system to increase the light intensity, so that the camera can clearly see Capture images of your surroundings. [0003] However, when the visual robot uses its own lighting system for supplementary light, the lighting system is usually on t...
