Abstract

The invention discloses a high-precision positioning method in an underground large space. network model; S3. Based on the trained deep learning network model, the pixel with the same name as the central pixel of the output spatial real-time image picture; S4. Based on the triangulation network model, the three-dimensional spatial coordinates of the center point are obtained by solving; S5. Draw the center Line, the intersection of the center line is the real-time position point. The present invention can perform real-time position positioning without GNSS signal and complex electromagnetic environment, and the positioning method of the present invention has low cost and can realize fast positioning.

Description

technical field [0001] The present invention relates to the technical field of spatial positioning. More specifically, the present invention relates to a high-precision positioning method in an underground large space. Background technique [0002] Facing the growing demand for high-precision positioning and navigation applications, most of the current conventional positioning services have some problems in complex buildings or in the underground space environment, and cannot provide real-time and reliable positioning services for large underground spaces. . [0003] Among them, satellite navigation needs to be used in new areas with wide field of vision and fewer obstacles, in the field, exploration and positioning, etc. In underground space, satellite signal quality is poor or satellites cannot be received at all, so real-time and accurate location services cannot be provided; WIFI positioning can be achieved. Complex and large-scale positioning is convenient for network...
