Embodiment 1

[0017] Embodiment 1: a kind of dynamic positioning system based on ultrasonic sensor, an ultrasonic transmitting module D, such as figure 1 shown.

[0018] The main control board is fixedly installed on the robot car body and is used to process ultrasonic signals and calculate the orientation of the robot car relative to the follower.

[0019] The ultrasonic transmitter module is carried by the follower, and when carried, the ultrasonic transmitter module should face the ultrasonic receiver module of the robot car, and keep its position on the follower.

[0020] Two sets of ultrasonic receiving modules are fixedly connected to both sides of the robot car respectively, and are at the same installation height.

[0021] Each group of ultrasonic receiving modules is composed of two ultrasonic sensors, which are used to receive the ultrasonic waves emitted by the ultrasonic transmitting module to expand the receiving range of ultrasonic waves. The installation methods of the ultra...

Abstract

The invention provides a dynamic positioning system and method based on an ultrasonic sensor and belongs to the technical field of information processing.Two groups of ultrasonic receiving modules are fixedly connected to the same height of a robot car; each group of ultrasonic receiving modules comprise two ultrasonic wave sensors, and an installation angle exists between the two ultrasonic wave sensors; an ultrasound transmitting module is carried by a follower; if the two ultrasonic wave sensors in the same group receive ultrasonic wave signals, the average value of the two ultrasonic wave sensors is taken to serve as the distance between a corresponding ultrasonic receiving component and the ultrasound transmitting module.The dynamic positioning system and method have the advantages that real-time positioning of the robot car relative to the follower is achieved; a positioning algorithm is efficient and practical; a positioning blind area is reduced, good positioning precision and a large positioning range are achieved.

Description

technical field [0001] The invention relates to a dynamic positioning system and method based on an ultrasonic sensor, belonging to the technical field of information processing. Background technique [0002] Following the robot can help people solve many problems in real life, such as autonomously following the camera, following the shopping, following the lead, etc. Therefore, following the robot is becoming a major trend in the development of robots. If the robot is to follow people, the problem that must be solved is that the robot can determine its position relative to the follower in real time, that is, the small-scale positioning problem. At present, the main methods to solve this problem include radio frequency positioning, binocular vision positioning, ultrasonic sensor positioning, etc., but the existing solutions have some shortcomings. Affected by light intensity, ultrasonic positioning has the problem of small positioning range and poor positioning accuracy. ...
