Embodiment Construction
[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] The method of the present invention is carried out indoors, such as shopping malls, hospitals, conference halls, supermarkets and other places. In such occasions, outdoor GPS positioning is relatively inaccurate. In order to solve the problem of the accuracy of the indoor environment, the method of fingerprint positioning is used Indoor positioning is carried out, and smaller areas are divided in this large area, so that the approximate range of positioning determination is narrowed down. At the same time, the signal strength value is used to divide each small area to determine the signal strength value and establish a one-to-one correspondence with the coordinates. The mapping relationship, and finally use the K-nearest neighbor algorithm to match when matching to make the matching degree higher and improve the positioning accuracy.
