Abstract

The invention discloses a real-time map construction system, method and device. The real-time map construction system includes a laser ranging module, a positioning module, a map drawing module and a vision acquisition module. The triangulation method of the laser ranging module and the differential positioning of the positioning module are utilized, and the vision acquisition module and a mobile support platform are utilized in combination, and an OpenGL drawing method is adopted, and therefore, the construction of an all-dimensional real-time two-dimensional and three-dimensional map of an unknown environment can be realized. The real-time map construction system, method and device have the advantages of high map drawing accuracy, high map drawing efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of robot map construction, in particular to a robot omnidirectional real-time map construction system, method and device. Background technique [0002] Map drawing is a difficult robotic technology, especially the map perception and drawing of unfamiliar environments, which is a basic and important problem in the field of mobile robots. The robot starts to move from an unknown unknown in an unknown environment, locates itself according to unknown estimation and sensor observation during the movement process, and builds an environmental map at the same time. [0003] The existing map drawing generally uses a laser rangefinder to measure the distance of each point and then manually calculates and draws it, which is very inefficient. There is currently no device that automates real-time mapping. Contents of the invention [0004] Based on this, it is necessary to provide an intelligent and automatic real-ti...
