Abstract

The invention provides a cleaning path planning method and device. The method includes: processing the area to be cleaned to obtain the central skeleton line of the area to be cleaned; taking the central skeleton line as the baseline and taking the technical parameters of the vehicle as the translation distance, respectively upward and downward Translate down to obtain the first polyline set and the second polyline set; respectively process the edges of the first polyline set and the second polyline set to obtain the first curve set on the first side of the area to be cleaned and the first curve set of the area to be cleaned. The second set of curves on both sides; splicing the first set of folded lines, the second set of folded lines, the first set of curves and the second set of curves to obtain the original planning path covering the area to be cleaned; After smoothing, the target planning path covering the area to be cleaned is obtained. Thus, it is ensured that the path planning satisfies the vehicle kinematics constraints, thereby ensuring the validity and rationality of the generated planned path.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a cleaning path planning method and device. Background technique [0002] In recent years, with the rapid development of artificial intelligence technology, autonomous driving technology has increasingly entered people's field of vision. Especially in some specific areas, unmanned vehicles used for logistics, cleaning, etc. are gradually changing people's lives. [0003] For unmanned sweepers, how to clean as much as possible in a specific area is particularly important. Therefore, how to design a full-coverage path that satisfies the motion constraints of the vehicle and can traverse the entire area as much as possible is of great significance. [0004] At present, the most widely used full-coverage path planning method is grid-based planning, which is mainly applied to small sweeping robots. [0005] The grid-based full-coverage path planning method is mainly realized by using...
