Abstract

A positioning method, comprising: receiving a first signal sent by a first base station and a second signal sent by a second base station, and calculating the relationship between the measured target and the first base station and the second signal according to the time difference between the received first signal and the second signal The distance difference measurement value of the distance between the two base stations obtains the first measurement speed of the measured target relative to the first base station and the second measurement speed relative to the second base station, and according to the distance difference measurement value, the first measurement Measure the speed and the second measurement speed to obtain more than one measurement coordinates, calculate the estimation function corresponding to each coordinate point in the area surrounded by more than one measurement coordinates, and the position of the measured target is the coordinate corresponding to the smallest estimation function point. The disclosure also provides a positioning device, electronic equipment and a storage medium. The method proposed in the present disclosure can realize the positioning of the measured target when there are only two base stations, and has the characteristics of high robustness and high positioning accuracy.

Description

technical field [0001] The present disclosure relates to the technical field of positioning, and in particular, to a positioning method, device, electronic equipment, and storage medium. Background technique [0002] With the rapid development of digital communication and multimedia services, the importance of location information is constantly increasing, so that the positioning problem has been widely concerned by people. At this stage, the positioning technology represented by GPS can better realize outdoor positioning, but the solution for indoor precise positioning is still in the research stage. [0003] At present, indoor positioning technology is mainly based on Wifi, optics, geomagnetism, audio and other technologies. Indoor positioning methods mainly include fingerprint method, positioning method based on direction angle, positioning method based on time difference of Time of Arrival (TOA for short) positioning method, etc. Among them, the fingerprint method need...
