Title: INDOOR MAP CONSTRUCTION METHOD, DEVICE, AND STORAGE METHOD
Abstract:
An indoor map construction method, device, and storage method. The indoor map construction method comprises: acquiring laser point cloud data collected by a laser point cloud device (S110); aligning, on the basis of key frame point cloud data in the laser point cloud data, the laser point cloud data, and forming, on the basis of an alignment result, a three-dimensional image of an indoor area (S120); and partitioning the three-dimensional image of the indoor area to form an indoor map (S130). The indoor map construction method addresses a current issue of high worker competence requirements and labor intensiveness due to a need to hire a large number of workers with professional map drawing skills and a need for the workers to personally visit an indoor environment to collect measurements and manually drawing the map. The invention thereby achieves the goals of reducing worker competence requirements, lowering labor intensity, and improving the precision of the constructed indoor map.
