Problems solved by technology

When the sensor is used in the indoor composition of the robot, it often only detects obstacles at a certain height. When encountering protruding edges such as table corners, the robot often cannot effectively avoid obstacles.
Therefore, the edge detection in the two-dimensional planar map obstacle avoidance method is prone to failure
[0006] Traditional indoor mobile robots usually use laser equipment for navigat

Abstract

A mobile navigation method and system comprise a sensor, a computer processing unit and a driving mechanism. The sensor is used for collecting environmental data. The computer processing unit is used for calculating the collected data from the sensor to build a 3D map, and a path planning from a start point to a destination point is provided according to the 3D map. The driving mechanism is used for driving a mobile navigation system to move according to the path provided by the computer processing unit. The mobile navigation method and system further provide a map building method and a path planning method by using the mobile navigation system.

Description

【Technical Field】 [0001] The invention relates to a mobile navigation method and a mobile navigation system. Specifically, the present invention relates to a method and system for a robot to realize the navigation function through real-time synchronization of environment map construction and positioning in an unknown indoor environment. 【Background technique】 [0002] In recent years, mobile robot technology has continuously developed and matured. Some indoor mobile robots often appear in indoor scenes such as factories, exhibitions, airports, and museums. These robots have various functions, such as welcoming guests, leading the way, patrolling, security and so on. A very important basic function of indoor mobile robots is navigation. In navigation technology, environmental map information and robot positioning technology are the prerequisites for robots to move autonomously. With this prior information, path planning and obstacle avoidance technologies can play a role in driv...
