A positioning method, device, electronic equipment and readable storage medium

Abstract

Embodiments of the present invention provide a positioning method, device, electronic equipment, and readable storage medium, which are applied in the field of wireless positioning technology. The method includes: according to the signal information values ​​of signals transmitted by multiple base stations received by the mobile station, by The differential method obtains the signal eigenvectors corresponding to multiple base station pairs; for each base station pair, if the signal eigenvectors corresponding to the base station pair are not in the label database, input the signal eigenvectors into the pre-established non-line-of-sight error calculation model to obtain the non-line-of-sight error calculation model line-of-sight error value; if the signal eigenvector is in the tag database, the signal eigenvector is expanded, and the non-line-of-sight error corresponding to the expanded signal eigenvector is obtained according to the tag database; the signal eigenvalue in the signal eigenvector The sum of the non-line-of-sight error value and the non-line-of-sight error value is used as the corrected signal feature value; according to the obtained multiple corrected signal feature values ​​and the position calculation formula, the position coordinates of the mobile station are obtained. The invention can improve the positioning accuracy.

Description

technical field [0001] The invention relates to the technical field of wireless positioning, in particular to a positioning method, device, electronic equipment and a readable storage medium. Background technique [0002] With the rapid development of Internet technology, indoor and outdoor integrated high-precision positioning technology not only has important applications in the medical industry, online travel, fire rescue, smart city, Internet of Things, etc., but also becomes the "Internet +" economy. Important booster. [0003] Existing positioning algorithms can generally be divided into ranging-based positioning algorithms and ranging-free positioning algorithms. The positioning algorithm without ranging does not need to measure the ranging information between the base station and the positioning terminal, so the hardware cost is low, easy to implement, and is not interfered by factors such as multipath non-line-of-sight, but the positioning accuracy of the positioni...

AI Technical Summary

Problems solved by technology

It can be seen that the accuracy of determining the non-line-of-sight error in the above positioning method based on non-line-of-sight error compensation is low, resulting in low positioning accuracy
