Robot-based indoor positioning and navigation system and method

Abstract

The invention relates to a robot indoor positioning and navigation system and method; the system comprises a main control computer and a mobile device which is provided with a robot, a first camera and a light generator; the first camera and the light generator are arranged on the robot; a coordinate system which can be displayed under light illumination is arranged on the indoor ground; the light generator is used for emitting set light to the indoor ground; the first camera is used for obtaining a displayed coordinate image and sending the image to the robot; the robot is used for identifying the coordinate image to obtain a current position digital coordinate of the robot in the indoor coordinate system and sending the current position digital coordinate to the main control computer; the main control computer is used for determining a current position of the robot according to the current position digital coordinate and the pre-stored coordinate system, and also is used for converting the target position into a target position digital coordinate according to the pre-stored coordinate system and generating a navigation signal according to the current position digital coordinate and the target position digital coordinate. The system makes the robot positioned and navigated accurately on the indoor ground.

Description

technical field [0001] The present invention relates to the technical field of robots, in particular, to a robot-based indoor positioning and navigation system and a method thereof. Background technique [0002] Due to its autonomous positioning function, autonomous mobile robots have been more and more widely used, among which indoor robots are a research hotspot. However, since the robot is not completely intelligent, the positioning and navigation technology is the key to the intelligent and fully autonomous movement of the robot. Especially when the robot needs to complete indoor motion, it becomes the key to solve the problem of robot position determination and navigation. At present, although with people's in-depth research on positioning and navigation technology, it is gradually realized that the robot can move along the planned arbitrary path and complete the assigned task under the condition of no human intervention, but there are defects. [0003] In the traditio...

AI Technical Summary

Problems solved by technology

The methods mentioned above are widely used, and can obtain satisfactory accuracy and reliability in structured environments, but the environmental information obtained by these methods is very limited, and basically can only be used in simple and fixed environments, and due to indoor Due to the shielding of the moving space and the requirements for positioning accuracy, traditional methods such as satellite positioning often cannot meet the requirements

For example, GPS cannot work normally indoors. In this environment, GPS positioning is slow or even impossible, and it is not accurate enough.

[0004] In addition, other technologies such as fixed signal generator positioning, infrared light projection, etc. can also be used for positioning, but the positioning accuracy is not ideal
