Positioning and navigation method based on depth camera and laser radar device

Abstract

The invention discloses a positioning and navigation method based on a depth camera and a laser radar device. The 2D and 3D information collected by sensors is utilized to carry out indoor environmentmodeling, position analysis and information calibration; the present scene information is collected by a user, and rapid comparison and accurate characteristic matching of the collected information with the 2D and 3D environment model information are carried out to realize indoor positioning of the user; the positioning method is accomplished through respectively establishing a data acquisition device and a data analysis platform for indoor positioning; the data acquisition device comprises the depth camera and an inertia measurement sensor, and indoor 2D and 3D information, attitude and drift angle space information acquisition of any position can be accomplished; the data analysis platform can be used for carrying out rapid storage, position analysis and information calibration of the environment model through utilizing the acquired 2D and 3D information, the positioning result acquired through analysis is fed back to the user in real time, and the indoor positioning function is realized.

Description

technical field [0001] The invention relates to the technical field of automation, in particular to a method for sharing and using autonomous obstacle avoidance navigation information and an autonomous obstacle avoidance navigation system applied to robots. Background technique [0002] With the development of science and technology, the application fields of robots are becoming more and more extensive. Their application in different industries can bring innovations in industry applications and superimposed leaps across industries. At the same time, the grand goal of "every family has robots" also gradually realized. But on the road to the popularization of robots, the most important thing is the automatic obstacle avoidance and navigation technology that is closely related to safety. If the safety of robots and personnel cannot be guaranteed, everything else will be out of the question. [0003] The robot's autonomous obstacle avoidance navigation system is a hot issue in ...

AI Technical Summary

Problems solved by technology

[0004] Due to the existing technology, the positioning service provider needs to deploy a large number of transponders or beacons in advance to receive the user's transmission signal in real time, and requires the object to be measured or the user to install or wear the same technology at the same time. Signal transmitting or collecting devices make the hardware cost of current indoor positioning services high, and it is very inconvenient to use and maintain

[0005] In addition, since the deployed transponders have certain restrictions on the conditions of the deployment area, service providers are also required to conduct relatively accurate indoor plane mapping, which further increases the service cost of indoor positioning.
