Abstract

An indoor positioning method adopts an intelligent device provided with a camera, and a position information map, an image recognition module and a position calculation module are arranged in the intelligent device. The position positioning method comprises the following steps: (1) the camera is turned on, and photographs a target object to obtain the images of the target object; (2) the image recognition module recognizes the images of the target object to obtain corresponding target object information and the position information of the target object relative to the intelligent device; (3) the position calculation module calculates according to the corresponding target object information to obtain distances D1 and D2 of two ends of the target object to the center point of the camera; (4) two intersecting circles are formed by adopting the two ends of the target object as circle centers and the corresponding distances D1 and D2 as radiuses, and the position calculation module calculates the coordinates of two crosspoints; and (5) the coordinates of the two crosspoints are displayed on the position information map, and the correct one of the coordinates of the crosspoint selected as the coordinate of the center point of the camera according to the position information of the target object relative to the intelligent device.

Description

technical field [0001] The invention relates to an indoor positioning method. Background technique [0002] Global Positioning System (GPS for short) is the current mainstream positioning technology. GPS is a navigation system combined with satellite and wireless technology, which can provide users with accurate positioning. Users can easily use GPS to obtain positioning and navigation information as long as they are in an area where satellite signals can be received. [0003] However, a GPS receiver located in an indoor environment is likely to be unable to perform positioning due to poor reception of GPS signals due to shading of buildings. Therefore, it is necessary to develop a positioning technology for indoor environment positioning. At present, the main indoor positioning technology includes geo-marking positioning method and distance estimation positioning method. [0004] The positioning information obtained by the geo-marking positioning method is the position i...
