Dividing method for working region of self-moving device, dividing apparatus, and electronic device

Abstract

The present invention relates to a moving method of a self-moving device, including: presetting a preset movement path of a self-moving device; enabling the self-moving device to move along the preset movement path; and checking whether a moving direction of the self-moving device deviates from the preset movement path, and when the moving direction deviates from the preset movement path, calibrating the moving direction of the self-moving device to enable the self-moving device to move along the preset movement path, wherein, the preset movement path including several first path segments, the first path segment being divided into several sub-path segments, and an end point of the sub-path segment being referred to as a node; and the calibrating the moving direction of the self-moving device includes: calibrating the moving direction of the self-moving device by using the node as a target point.

Description

BACKGROUNDTechnical Field[0001]Embodiments of the present invention relates to self-moving devices, and in particular, to a dividing method for a working region of a self-moving device, a dividing apparatus, and an electronic device.Related Art[0002]An autonomous working system such as an autonomous lawn mower system can autonomously complete a lawn maintenance task or the like, and becomes increasingly popular among consumers. In the autonomous working system, a self-moving device such as an autonomous lawn mower is restricted to move inside a working region. When the autonomous lawn mower leaves the working region, a safety problem may occur. In addition, an obstacle may exist in the working region. The obstacle includes a pit, a flowering shrub, and the like. The autonomous lawn mower should avoid the obstacle in the working region during working to prevent accidents such as falling or trapping. To ensure the safety of the autonomous working system and improve the working efficie...

AI Technical Summary

Benefits of technology

The patent text discusses the problem of autonomous lawn mowers deviating from their expected path due to relatively large areas and small navigation positioning errors. The text proposes a solution to improve working precision by selecting the direction in which the mower enters a shaded region to shorten the duration it remains in the shaded region. This reduces the deviation from the expected path and improves the accuracy of the mower's positioning.

Problems solved by technology

When the autonomous lawn mower leaves the working region, a safety problem may occur.

In addition, an obstacle may exist in the working region.

Such a method requires complex arrangement of a boundary line and adversely affects the look of a lawn.

Another technical problem that follows is how to set more appropriately divided regions according to a feature of a working region, so that the autonomous lawn mower can safely and efficiently cover the working region.

However, because a lawn on which an autonomous lawn mower works usually has a relatively large area, a relatively small navigation positioning error may result in a relatively large deviation from an expected path.

Therefore, how to reduce a walking deviation of an autonomous lawn mower to improve working precision is a problem that urgently needs to be resolved in autonomous lawn mower technologies.

Buildings and obstacles usually exist in a working region of an autonomous lawn mower.

Satellite navigation signals usually tend to be blocked by the buildings, the obstacles, and the like and become weaker consequently.

For example, an autonomous lawn mower may fail to be located precisely when working in a shaded region due to weak GPS signals.
