Problems solved by technology

[0004] However, in the prior art, there is a certain error in the moving distance detected by the wheel odometer (for example: in the running process, the wheel slips, and at this time, the moving distance recorded by the wheel odometer is greater than the actual moving distance). With the increase of the moving distance, the error accumulates, making the positioning more and more inaccurate

Abstract

The present invention provides a positioning method and device. The method includes the following steps that: the area map of a target area is built in advance, and at least one sonar waveform of eachposition in the area map is determined; positioning sound waves are transmitted at a current position; the echoes of the positioning sound waves are received; and a current sonar waveform corresponding to the current position is determined according to the echoes of the positioning sound waves; a target sonar waveform similar to the current sonar waveform is determined from the at least one sonarwaveform in the area map; and a target position corresponding to the target sonar waveform is determined as the current position. With the positioning method and device of the invention adopted, positioning can be performed more accurately.

Description

technical field [0001] The present invention relates to the field of electronic technology, and in particular, to a positioning method and device. Background technique [0002] With the rapid development of science and technology, there are more and more regional devices that can automatically move in the target area, such as sweeping robots. Among them, positioning in the target area is an important technology to realize these devices. [0003] In the prior art, positioning in the target area is mainly realized based on the recording of the moving distance and the moving direction. Specifically, a wheel odometer is provided in the device, the moving distance of the device is recorded by the wheel odometer, and the moving direction of the device is recognized by a sensor that senses the direction. When the starting point is known, the current position is calculated through these data to realize positioning. [0004] However, in the prior art, there is a certain error in t...
