Embodiment Construction

[0067] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0068] The invention provides a method for optimally arranging artificial road signs and a corresponding robot positioning method. The optimal layout method of landmarks, which arranges the same landmarks in the environment, the single landmarks observed by the sensor have the same characteristics, and m landmarks within the sensor field of view are used as the basic unit of robot positioning, and the characteristic of the basic positioning unit is the distance between landmarks Spatial position relatio...

Abstract

The invention provides a road sign arrangement optimizing method and a corresponding robot positioning method. Road sign arrangement in the environment is optimized. Each positioning basic unit is formed through a plurality of road signs. All the positioning basic units in the overall environment form a road sign map. Difference degrees are defined. The road sign arrangement is optimized to make the difference degrees maximum, thus increasing reliability of map matching and increasing reliability of robot positioning. In the positioning method, sensors detect the road signs, match with the road sign map, and determine positions of robots after success matching. The road sign arrangement optimizing method and the corresponding robot positioning method are advantaged by easy road sign recognition, high reliability of map matching, high reliability of positioning, wide applications, and the like.

Description

technical field [0001] The invention relates to the field of robot positioning, in particular to a method for optimally arranging road signs and a corresponding robot positioning method. Background technique [0002] Achieving high-reliability and high-precision robot positioning is a prerequisite for robots to complete related tasks. The positioning method based on artificial landmarks can obtain high reliability and high positioning accuracy, so artificial landmarks are widely used in the positioning system of robots. [0003] In the landmark-based robot positioning system, the reliability of landmark recognition directly determines the reliability of the robot positioning system. [0004] After searching, the following relevant patent documents were found.
