Embodiment Construction

[0061] In order to make the purpose, technical solutions and advantages of the present application, the present application will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended to explain the present application and is not intended to limit the present application.

[0062] Synchronous Positioning and Map Building (SLAM) technology is a key technique for achieving full self-motion positioning navigation. SLAM technology is in an environment in which the tunnel, promgadic environment is unable to be effective in a large-scale empty environment, or in a large-scale environment, or other environments that cannot be effectively restrained in a certain direction, or other environments that cannot be effectively restrained in a certain direction. The ability to identify and the positioning accuracy is not high.

[0063] Then, this paper proposes a method and...

Abstract

The invention relates to a mapping and positioning method and device based on data fusion of two sensors. The method comprises the following steps: acquiring external parameter information of the distance measuring device installed on the movable platform; in the moving process of the movable platform, obtaining distance information between the distance measuring device and the at least one distance measuring base station in real time; building a sensor through instant positioning and a map, and obtaining the relative pose relation of the movable platform between two different moments; and performing data fusion on the basis of the external parameter information and the distance information and the relative pose relation acquired in the time period to obtain a target map. The method and device have higher mapping or positioning precision.

Description

Technical field [0001] The present application relates to artificial intelligence technology, and in particular, it is related to the construction and positioning method based on two sensor data fusements. Background technique [0002] As the development of positioning technology, synchronous positioning and map construction (SLAM) technology becomes an important positioning navigation technology. SLAM technology refers to the technique of building data in real-time acquisition environments in real-time acquisition environments in real-time acquisition environments in real-time real-time acquisition environments in real time without environmental prior information. [0003] As the accuracy of the positioning technology is getting higher and higher, the disadvantage of SLAM technology is that the accuracy of the SLAM is seriously affected in the insufficient information of the environment or the characteristics of the environment. Inventive content [0004] Based on this, it is n...
