Embodiment Construction

[0055] A road full traversal cleaning path planning method for unmanned sweeping vehicles, such as figure 1 , including the following steps:

[0056] 1. Classification of road types

[0057] Divide road types into single-lane roads, two-lane roads and multi-lane roads; unmanned sweepers judge whether the road to be cleaned is a single-lane road or a two-lane road based on high-precision maps and on-site visual recognition (such as its own visual sensor, etc.) Or multi-lane roads, according to the type of road to take the corresponding path planning method. High-resolution maps are pre-scanned.

[0058] The invention mainly plans and cleans urban roads, and classifies urban roads into single-lane, double-lane and multi-lane. Among them, the multi-lane is similar to the double-lane situation, except that the median strip is replaced by the middle lane line, which can be regarded as an extension of the double-lane, so the multi-lane processing method is similar to the dual-lan...

Abstract

A method for planning a road full traversal cleaning path for an unmanned sweeper, comprising the following steps: the unmanned sweeper judges the type of road to be cleaned; if it is a single lane, autonomously recognizes the edge of the road, marks the edge of the road as an adjacent cleaning area, According to the relevant traffic rules, give priority to cleaning the side-by-side cleaning area, and plan a spiral inward cleaning path; if there are two or more lanes, independently identify the edge of the road and the middle lane line or the middle isolation belt, so as to give priority to cleaning the side-by-side cleaning area , Secondly, clean the middle lane line area or the middle isolation belt area, and finally clean the area inside the lane as the principle to plan the cleaning path. The planning of various paths in the present invention complies with traffic rules, has no retrograde risk, and will not drive against or across the middle lane line or the middle isolation belt, ensuring driving safety; the "spiral inward" path and cleaning sequence can ensure Safe driving, avoid missed and repeated cleaning, and improve cleaning efficiency.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a method for planning a road full traversal cleaning path for an unmanned cleaning vehicle. Background technique [0002] In recent years, with the rapid development of artificial intelligence and robot technology, autonomous driving technology has been more and more applied to various industries. As one of the most popular unmanned products, driverless sweepers are gradually expanding from closed structured scenarios to unstructured dynamic environments such as urban roads. For unmanned sweeping vehicles, from structured closed scenes to extended applications of urban road scenes, how to ensure full traversal and high-efficiency cleaning effects on the basis of abiding by road traffic rules is an urgent priority to be solved. The existing mainstream technology of unmanned cleaning mainly has the following problems: (1) Full traversal is not realized: most unmanned sweeping vehic...
