Problems solved by technology

[0003] The round-trip path planning strategy used in the prior art has the problem of insufficient automation
In other words, most of the round-trip path planning strategies in the prior art require human participation, especially when planning paths for irregularly shaped plots, it is more dependent on human participation
This will restrict the advancement of agricultural automation

Embodiment approach

[0098] As an implementation manner, the formula can be used according to the second abscissa value, the path traversal direction and the preset distance:

[0099] x le =x pe +T w ×D / 2;

[0100] Calculate the first abscissa value of the point to be determined. where x le is the first abscissa value of the point to be determined, x pe is the second abscissa value. T w is a value representing the path traversal direction, optionally, when the path traversal direction is the positive direction of the abscissa axis, T w =1, when the path traversal direction is the negative direction of the abscissa axis, T w =-1. D stands for quarter preset spacing.

[0101] S102-1-2, under the first abscissa value, acquire the first ordinate value of the point to be determined.

[0102] In some embodiments, under the first abscissa value, the ordinate value corresponding to the point whose minimum distance from the first inspection side does not exceed a preset value can be obtained as ...

Abstract

Embodiments of the present invention provide a round-trip route planning method, device and electronic equipment, which relate to the technical field of route planning. It can be applied to polygonal job plots. Specifically, the above round-trip path planning method includes confirming the first check edge and the second check edge in the forward direction of the current straight segment. The straight line end point of the current straight line segment is determined based on the turning radius and the preset distance of the operating equipment, so that the U-turn trajectory using the straight line end point as the starting point does not exceed the first inspection side and the second inspection side. In this way, even in the face of irregularly shaped plots, high-safety path planning can be fully automated to promote the development of agricultural automation.

Description

technical field [0001] The present invention relates to the technical field of path planning, in particular to a round-trip path planning method, device and electronic equipment. Background technique [0002] In the process of agricultural automation, operating equipment that can move and perform autonomous operations plays an important role. For the above-mentioned operating equipment, path planning is very important, which determines the effective operating range of the operating equipment on the operating plot. A round-trip path is a path that improves the effective working range better than other paths. [0003] The round-trip path planning strategy used in the prior art has the problem of insufficient automation. In other words, most of the round-trip path planning strategies in the prior art require human participation, especially when path planning for irregularly shaped plots is more dependent on human participation. This will restrict the advancement of agricultu...
