Method and device of robot positioning and navigation

Abstract

The invention relates to a method and a device of robot positioning and navigation. The method comprises the following steps: recording the indoor mobile position and the corresponding image with a depth camera; analyzing the mobile position and image of a robot returned by the depth camera to match image feature points and physical feature points to determine the position, direction and environment of the robot; obtaining the whole indoor map browsing system according to the matching information between image feature points and physical feature points and the determinate position, direction and environment of the robot; receiving a task execution instruction sent by a user, projecting an optimum collisionless route, and finishing the task by the robot according to the optimum collisionless route or sending the map information and positioning information to a robot without sensing ability by the robot to execute the task according to the optimum collisionless route. The precision of the robot positioning and navigation is improved, constructing cost of the hardware is reduced greatly, and the other robot or smart home device is controlled by the robot.

Description

technical field [0001] The invention relates to a positioning and navigation method and system, in particular to a robot positioning and navigation method and system. Background technique [0002] Household robots on the market, such as sweeping robots, currently rely mainly on wireless positioning technologies for indoor positioning and navigation, such as existing technologies such as WiFi (Wireless Fidelity), infrared and Bluetooth, but these wireless positioning technologies have their shortcomings, as follows: [0003] Wi-Fi technology, wireless local area network (WLAN) is a brand-new information acquisition platform, which can realize complex and large-scale positioning, monitoring and tracking tasks in a wide range of application fields, and the positioning of network nodes itself is the basis of most applications and premise. The accuracy of Wi-Fi mapping is on the order of 1 meter to 20 meters, and overall it is more accurate than cellular network triangulation po...

AI Technical Summary

Problems solved by technology

The disadvantage is that the price of Bluetooth devices and equipment is relatively expensive, and for complex space environments, the stability of the Bluetooth system is slightly poor, and it is greatly disturbed by noise signals.

[0006] However, the existing robot positioning and navigation technology often has various problems such as low positioning accuracy or high hardware installation costs.
