The embodiment of the invention provides a positioning method and device, an electronic device and a readable storage medium, which are applied to the technical field of wireless positioning. The method comprises the steps that according to the signal information value of signals which are transmitted by a number of base stations and are received by a mobile station, signal feature vectors corresponding to multiple base station pairs are acquired through a difference method; for each base station pair, if the signal feature vector corresponding to the base station pair is not in a tag database, the signal feature vector is input into a pre-established non-line-of-sight error calculation model to acquire a non-line-of-sight error value; if the signal feature vector is in the tag database, dimension expanding is carried out on the signal feature vector, and the non-line-of-sight error corresponding to the signal feature vector after dimension expanding is acquired according to the tag database; the sum of a signal feature value in the signal feature vector and the value of the non-line-of-sight error is used as a corrected signal feature value; and the position coordinate of the mobile station is acquired according to a number of acquired corrected signal feature values and a position calculation formula. According to the invention, the positioning accuracy can be improved.
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...
