Abstract

The invention relates to a local area positioning method and system. The method comprises the steps of: receiving a positioning signal transmitted by a sensor deployed in a local area to be positioned according to a data receiving port preset on a designated webpage; locking the local area according to the positioning signal and acquiring sample data in the locked local area; drawing a local area map based on the sample data, and marking map coordinates in the local area map according to the image size of the local area map; according to a position fingerprint positioning algorithm, calculating the actual positions of various coordinates for the sample data and positioning signals, inputting a calculation result into the map coordinates corresponding to the local area map to generate an actual map of the local area. The method and system can lock the target local area through the deployed sensor, and calculate the actual position in the drawn local area map to obtain the actual map of the local area, and solve positioning incapability in the local area environment where the satellite and other positioning signals cannot be received.

Description

technical field [0001] The invention relates to the field of positioning and navigation, in particular to a local area positioning method and system. Background technique [0002] Satellites and other external signals cannot be received in the environment of some local areas, so some current mainstream maps cannot generate electronic maps for this local area, cannot determine the current location, and cannot perform positioning and navigation for this local area. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a local area positioning method and system, which can lock the target local area through deployed sensors, and calculate the actual position in the drawn local area map, thereby generating a local area on-the-spot map, solving Solved the problem of inability to locate in the environment of local areas where satellites and other positioning signals cannot be received. [0004] The technical solution of the ...
