Method and device for building robot work area map, robot and medium

Abstract

The embodiment of the invention provides a method and a device for building a robot work area map, a robot and a medium. The method comprises the following steps: scanning a barrier in a driving routein real time and recording a position parameter of the barrier; acquiring image information of the barrier in the driving route in real time; determining benchmark information of the barrier based onthe work area according to the position parameter and the image information; dividing the work area into a plurality of subareas based on the benchmark information. Through a radar scanning and camera shooting double-insurance mode, the identification accurate rate of a room door is greatly increased and room segmentation disorder caused by misidentification of the room door is avoided.

Description

technical field [0001] The present disclosure relates to the field of control technology, and in particular to a method, device, robot and medium for constructing a map of a working area of ​​a robot. Background technique [0002] With the development of technology, various intelligent robots have emerged, such as sweeping robots, mopping robots, vacuum cleaners, weeders, etc. These robots can receive voice commands input by users through a voice recognition system to perform operations indicated by the voice commands, which not only liberates labor, but also saves labor costs. [0003] Existing sweeping robots use inertial navigation, lidar or cameras for map planning and navigation. When users use sweeping robots to sweep the floor, they will see the division of the cleaning area in real time on their mobile devices. However, such division of cleaning areas is not a room unit type. Divide the cleaning area into a plurality of zones arbitrarily based only on the coordinate...

AI Technical Summary

Problems solved by technology

In some specific situations, for example, the living room area of ​​the home is an area that is often walked around. When the user wants to set the robot to clean the living room area, the above-mentioned existing natural division method will bring trouble to the user, because the map It is formed in real time, and it is difficult for the user to let the robot go directly to the area to be cleaned during the next cleaning

[0005] The existing map formation method cannot effectively divide the room, and the user cannot accurately designate a specific cleaning room. For example, the living room is a frequently active area with a lot of dust, and the user cannot clearly and accurately instruct the sweeping robot to go to the living room to clean the living room. clean the whole area

The current technology can only support the robot to reach the living room area, but it cannot guarantee that it will clean the entire area of ​​the living room after arriving
