Embodiment Construction

[0043] The following describes in detail a sonar-based robot tracking method of the present invention with reference to the accompanying drawings. It should be noted that the "first", "second", etc. in this article are only used to distinguish related terms, and do not indicate the level of importance.

[0044] Such as figure 1 As shown, in a sonar-based robot tracking method of the present invention, the mobile robot used is composed of a motion controller, multiple sonar transceivers, a servo controller, auxiliary sensors, mechanical transmission and other modules. The motion controller performs target positioning, path planning and real-time obstacle avoidance based on the data detected by the sonar transceiver.

[0045] The method of the present invention uses multiple sonar sensors for positioning and ranging. In order to locate the accurate position of the target and reduce the error as much as possible, the distribution distance of the two sonar transceivers on the robot is...

Abstract

A sonar-based robot tracking method and system, comprising: providing a sonar transceiver on a tracking target as a first routing node; and mounting two sonar transceivers on a robot, with one serving as a coordinator and the other one serving as a second routing node. A sonar transceiver is used to realize tracking target recognition and location, and obstacle ranging, thereby realizing multiple uses of a single sensor, so that not only is the product function realized, but the manufacturing cost is also reduced. Furthermore, information about an obstacle in the external environment can be quickly detected. The structure is simple, positioning and tracking are accurate, and the application value is high.

Description

Technical field [0001] The invention belongs to the technical field of mobile robot tracking and positioning, navigation, and obstacle avoidance, in particular to a sonar-based robot tracking method. Background technique [0002] In order to make robots serve specific target objects and help people complete tasks, such robots are required to have the functions of target recognition and autonomous navigation. At present, robots with target recognition and autonomous navigation generally recognize targets through "machine vision systems" and assist other sensors to complete autonomous navigation functions. [0003] "Machine vision" is to simulate human visual functions, obtain target information, and process target information. According to different visual sensor data, it is divided into "monocular vision" and "binocular vision". The expression of the target by the "monocular vision system" is mainly reflected in the brightness, texture, surface contour, shadow, etc. of the two-di...
