Research on mapping technology of indoor mobile robot based on linear fitting

Intelligent robots work in various complex, unknown and unstructured environments such as space, underwater, underground and field. Detection environment and map building is an important direction in the field of robot research. Based on the linear fitting algorithm, this paper studies the obstacle detection and environment map construction technology of indoor mobile robot. Firstly, the principle and characteristics of laser rangefinder are introduced. Secondly, the method of variable threshold adaptive separation and statistical calculation of linear parameters is used to detect the surrounding environment. The accurate local line segments are obtained through analysis, and then the global map is constructed. In this paper, Matlab is used to simulate and verify the technology, and the effect of drawing under different thresholds is compared.
