AI Technical Summary

Technical Problem

During the mapping process, due to the influence of mirrors, smooth surfaces, or impassable areas, areas that do not actually exist may be formed in the map, resulting in unrealistic map boundary expansion, which affects the task execution of the cleaning equipment and the user experience.

Method used

During the movement of cleaning equipment, a perception map is constructed, perception data and exploration paths are saved, and scattering areas are removed through flooding algorithms and exploration path detection. The map is then partitioned to generate an accurate partitioned map.

Benefits of technology

The task execution performance of cleaning equipment has been optimized, improving the user experience, ensuring the accuracy and reliability of the map, and avoiding unnecessary area cleaning.

Abstract

This application relates to a map generation method for cleaning equipment, a map display method, and a cleaning equipment itself. The map generation method includes: constructing a perception map during the movement of the cleaning equipment, and saving perception data and the exploration path of the cleaning equipment during the map construction process; after the perception map is constructed, removing scattering regions from the perception map based on the perception data and exploration path; scattering regions are areas that do not exist in the actual environment and areas that the cleaning equipment cannot pass through; and partitioning the perception map after removing scattering regions to obtain a partitioned perception map. This application solves the technical problem that during the mapping process of cleaning equipment, when encountering mirrors, smooth surfaces, or laser-visible areas that are actually impassable, non-existent areas are formed in the map, resulting in unrealistic expansion of the map boundaries, thus affecting the performance of the cleaning equipment and the user experience.
