Building positioning method, electronic device, storage medium and terminal device

An electronic device, comprising:

• at least one processor;
• and
• a memory communicatively coupled to the at least one processor;
• wherein
• the memory is stored with instructions executable by the at least one processor to enable the at least one processor to perform operations of:
• acquiring a building fingerprint library, the building fingerprint library. comprising a plurality of groups of triplet data and a plurality of corresponding building information, wherein a single group of triplet data. comprises surveying and mapping data, GPS data and Wi-Fi data;
• receiving a positioning request, the positioning request comprising first triplet data, the first triplet data comprising first surveying and mapping data, first GPS data, and first Wi-Fi data;
• calculating a similarity between the first triplet data and the plurality of groups of triplet data in the building fingerprint library, respectively;
• and
• determining building information corresponding to the positioning request according to the calculated similarity;
• wherein constructing the building fingerprint library comprises:
• collecting a plurality of groups of triplet data, annotating each group of triplet date with corresponding building information, using a plurality of groups of annotated triplet data as training data to train a neural network, and obtaining a building positioning model after training;
• inputting a plurality of groups of triplet data to be positioned into the building positioning model for positioning to obtain a plurality of building information;
• and
• constructing the building fingerprint library based on the plurality of groups of annotated triplet data and the plurality of groups of triplet data positioned by the building positioning model.
