Abstract
Description
technical field
[0001] The invention relates to the technical field of positioning, in particular to an indoor positioning method based on commodity pictures. Background technique
[0002] At present, the most used positioning method is the GPS satellite navigation and positioning system. It operates on 6 orbits of the earth through 21 plus 3 spare satellites. Each orbit forms an angle of 120 degrees. , so that at least 4 satellites can be observed at any time and any place on the ground at the same time, and then the distance between the GPS satellite and the receiver is calculated by the signal transmission time length, and then the longitude and latitude of the receiver are determined by the three-point positioning system. 4 satellites to determine the height of the receiver from the ground, and then use the map cached in the receiver to realize positioning and navigation. When using GPS positioning, it is necessary to ensure that there is no deviation in the orbit of th...

Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0017] see figure 1 : figure 1 It is the floor plan of the supermarket, with the supermarket as the positioning area, and various commodities are placed in different blocks and categories in the supermarket.
[0018] The indoor positioning method based on the product picture includes the following steps:
[0019] 1) Establishment of the database: draw the floor plan of the positioning area, and draw the commodity placement blocks in the floor plan, and number each block. The number is unique in the same positioning area. The map and number are sent to the location server and stored in the location server's database. Use image acquisition equipment to collect picture information of commodities in the positioning area, and use block numbers to number the picture information. Send the numbered picture information to the location server through...
