The invention discloses a mobile base station fingerprint identification and positioning method, comprising: step S1, obtaining the motion equation of the mobile base station; step S2, obtaining an offline fingerprint library according to the motion equation of the mobile base station; step S3, obtaining the field strength, and The field strength is compared with the key information stored in the offline fingerprint library, and a rough fingerprint identification is performed to obtain a rough position; step S4, obtain the motion equation of the device according to the rough position; step S5, according to the device's The equation of motion is to obtain an online fingerprint library; Step S6 is to use a dynamic tracking mode to perform fine fingerprint identification according to the online fingerprint library to obtain an accurate position. The present invention can meet the needs of fast positioning of users in the cluster when the base station is moving.
Description
technical field [0001] The invention relates to the field of positioning and navigation, in particular to a fingerprint identification and positioning method for a mobile base station. Background technique [0002] With the improvement of demand, more and more tasks cannot be completed by a single device, and multiple devices need to be jointly implemented. Clusters have become a common organizational form, and the scale of clusters is also increasing day by day. In the case of large-scale control, large-scale clusters, and large-scale mimicry, the determination of the relative positions of members in the cluster becomes a key technology to ensure the effectiveness of task execution. [0003] The base station provides the relative positioning field strength, and the member realizes the location determination method based on the location fingerprint identification. It has the characteristics of strong autonomy within the cluster, no need for complex calculations, and simple a...
