Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0015] The embodiment of the present invention discloses a method for making an indoor map, which is applied to the server side, and its flow chart is as follows figure 1 As shown, the method includes:

[0016] Step 11, preprocessing the indoor building structure diagram to extract the layer information required by the map to generate a picture file;

[0017] Step 12, converting the image file into a map data file for map editing;

[0018] Step 13, binding the corresponding map metadata for the map layer of the map data file, and saving the map data file bound with the map metadata in the spatial database;

[0019] At the same time, map elements can also be added to the map layer of the map data file, and corresponding map metadata ca...

Abstract

The invention discloses a method and a device for manufacturing an indoor map and positioning, applied to servers. The method for manufacturing the indoor map comprises the following steps: pre-processing a structure chart of an indoor building, for extracting layer information needed by the map, so as to generate a picture file; converting the picture file to generate a map data file for map editing; binding corresponding map metadata for map layers of the map data file, and saving the map data file bound with the map data file into a spatial database; extracting map data from the spatial database, and reducing to form map layers; and overlapping pattern layers on the map layers, so as to form a vectorized indoor map which is stored in internal storage of the server. With the adoption of the method and the device, the indoor map can be flexibly expanded, so that accurate positioning is realized.

Description

technical field [0001] The invention relates to the field of navigation systems, in particular to a method and device for making an indoor map and positioning. Background technique [0002] The indoor map enables users to use the precise positioning function to find the shops, toilets, elevators, rest areas, entrances and exits they want to go to in the building through mobile devices, and open up the relationship between "people, locations, and businesses". In addition to displaying the floor plan of the venue on mobile devices, the indoor map can also help users keep abreast of various information and search for products by category, which greatly facilitates users to understand unknown destinations and find the required information as quickly as possible. [0003] At present, the commonly used indoor maps are drawn through static pictures, the information stored in the pictures is relatively limited, and the scalability and flexibility of static pictures are relatively po...
