Method and system for updating local map on basis of existing map and medium

Abstract

The invention provides a method and system for updating a local map on the basis of an existing map and a medium, and relates to the technical field of local map updating, and the method comprises the steps: 1, judging a map region needing to be updated, and moving a robot to the region needing to be updated; 2, generating an initialized graph according to a region needing to be updated; 3, after the initialized graph is obtained, inputting the actual position of the robot on the map at the moment into the robot; 4, after the initialized map and the correct position of the robot in the map exist, enabling the robot to generate a map of the local area through the laser radar and odometer data of the robot body; and 5, after the map of the local area is obtained, storing the local map. The local map can be updated on the basis of the existing map, and the navigation and positioning problems caused by environment change are solved.

Description

technical field [0001] The present invention relates to the technical field of partial map updating, and in particular, relates to a method, system and medium for updating a partial map based on an existing map. Background technique [0002] Map update is the process of correcting the content of the map according to the actual situation, the purpose is to reflect the actual changes of human and natural elements in a timely manner, and maintain the current situation, accuracy and reliability of the map. [0003] Now Yunji Robot has provided various commercial service robot products and services for thousands of hotels, office buildings, shopping malls and other scenarios in China. More than a thousand robots serve human beings in various scenarios all the time. With indoor positioning and navigation and intelligent movement, Yunji robot can provide the functions of providing guidance and information promotion, and can also deliver things to people, thus providing convenience ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above existing technologies, there are the following technical defects. Before using the robot, it will input the overall map information in advance, but in the actual use process, the local position of the map will often change, such as adding a certain obstacle, etc. Changes in the environment cause misjudgment of navigation, and re-entering the overall map every time will make the operation process very cumbersome
