Problems solved by technology

[0004] However, due to multiple perturbations that exist in the actual operating environment, these disturbances include: shadows of objects; shadows of the lawn mower itself; reflected light and refraction; presence of dry grass; situation; different perception due to direction of travel; grains with non-nominal heights; perspective distortion due to uneven soil or vehicle tilt, etc.
Current image recognition methods are difficult to accurately identify the boundaries of the work area
[0005] Another situation is that when the existing self-mobile device returns to charge, it usually returns along the boundary line or the wall, which can ensure that the self-mobile device returns to the charging station for charging within a certain period of time, but if there is no boundary line, Or use other methods to guide the self-mobile device to return, and the coverage of these guide signals is relatively small compared to the working area, so the self-mobile device will take a long time to find the guide signal, and even cannot return to the charging station

Embodiment Construction

[0034] Such as figure 1 , the automatic working system of this embodiment includes a self-moving device 1 and a charging station 5, and the self-mobile device 1 walks and works in the working area, wherein the boundary 3 is used to limit the working area of ​​the automatic working system. The charging station 5 is used for mooring from the mobile device 1, especially returning to replenish energy when the energy source is insufficient. The autonomous mobile device 1 may be an automatic lawn mower, an automatic snow plow, etc., which automatically walk on the ground or surface of the working area to perform work such as mowing grass or snow plowing. In this embodiment, an automatic lawn mower is taken as an example of the self-moving device 1 .

[0035] Boundary 3 is a general term for the outer and inner boundaries of the working area. The outer boundary is the periphery of the entire working area, usually connected end to end, and encloses the working area. The inner bound...

Abstract

The invention relates to an edge control method of a self-moving device, the self-moving device moves and works in a working area, and the control method comprises the following steps: obtaining a digital image of a working surface of the self-moving device; processing the digital image based on a trained neural network to obtain a to-be-analyzed image; recognizing a working area boundary based on the to-be-analyzed image; and controlling the distance between the self-moving equipment and the boundary of the working area so as to control the self-moving equipment to move along the boundary of the working area. The self-moving equipment has the beneficial effect that the working efficiency of the self-moving equipment is improved.

Description

technical field [0001] The invention relates to a control method of self-moving equipment, in particular to a control method for image recognition based on artificial intelligence. Background technique [0002] With the development of science and technology, intelligent autonomous mobile devices are gradually known to people. Since self-mobile devices can automatically perform related tasks according to preset procedures without manual operation and intervention, they are widely used in industrial applications and household products. For example, industrial applications include robots that perform various functions, and household products. Applications include lawn mowers, vacuum cleaners, etc. These intelligent self-moving devices greatly save people's time and reduce their labor intensity, thereby improving production efficiency or quality of life. [0003] Generally, since the mobile device works in an area set by the user, the working area needs to be set by the user i...
