Intelligent robot positioning system and method based on radio frequency technology

Abstract

The invention relates to an intelligent robot positioning system based on a radio frequency technology. The system comprises a radio frequency tag, a high-frequency radio frequency transmitter, a high-frequency radio frequency receiver, a laser radar device and a processing and analyzing device, the processing and analyzing device is used for sending radio frequency information to each radio frequency tag through the high-frequency radio frequency transmitter when the intelligent robot is positioned, receiving tag information returned by the radio frequency tags through the high-frequency radio frequency receiver, and then determining the distance between the intelligent robot and each tag according to the tag information returned by the radio frequency tags. the processing and analyzing device is used for judging whether the distance between the intelligent robot and each label meets a boundary value or not, if so, determining that the intelligent robot is in a map boundary, and then detecting the environment through a laser radar device to obtain pose data of the intelligent robot. The problem that positioning is lost in similar scenes is avoided, and the situation that positioning deviates due to driving under the condition that the slope is too long is avoided.

Description

technical field [0001] The invention relates to the technical field of intelligent robots, in particular to an intelligent robot positioning system and method based on radio frequency technology. Background technique [0002] At present, the robot positioning and mapping method is based on the pure estimation method of laser radar, or combined with the odometer to confirm its own positioning. By obtaining the laser radar data and the odometer data for position fusion, it can determine where it is. The pose in the environment, and the map data in the environment are acquired synchronously, so that the robot can realize simultaneous positioning and map construction. However, in the process of similar scenes (such as long corridors), it is easy to lose the positioning during the positioning process; and the positioning algorithm combined with the odometer for position fusion is not suitable for the situation where there is a ramp in the environment, and it is easy to produce de...
