Indoor robot navigation device and navigation technology thereof

Abstract

The invention discloses an indoor robot navigation device which is characterized by comprising a circuit board, wherein a motion control module, a navigation and location module, a map management and path planning module, an image acquisition and processing module, a safety module and a man-machine interaction management module. The invention also provides an indoor robot navigation technology. The technology is characterized by comprising the following steps of: (a) establishing a map and planning a motion path of the robot; (b) refining a area and setting a visual signpost; (c) acquiring and processing the visual signpost, and performing motion location and correction; (d) storing and querying area and signpost information. The device has the advantages of autonomous navigation, high interference resistance capacity, zero track movement and the like, and the problem that most of the conventional navigation modes are low in positioning precision is solved through visual positioning correction.

AI Technical Summary

Problems solved by technology

The traditional navigation methods have more or less disadvantages, such as poor flexibility of electromagnetic navigation, inaccurate positioning, low intelligence and high maintenance costs for laying large-scale magnetic strips

Inertial navigation has good flexibility, but poor positioning accuracy, and it is easy to generate and accumulate deviations during the movement process, which is suitable for short-distance movement

Traditional visual navigation generally adopts multi-eye vision, which can achieve high positioning accuracy, but the amount of real-time calculations during the movement is large, not flexible enough, and it is greatly affected by the surrounding environment such as lighting; other navigation methods or multiple There are some disadvantages such as poor stability, low positioning accuracy, or high layout and maintenance costs
