Abstract

Embodiments of the invention disclose a prediction method and apparatus for positioning trajectories. According to a technical scheme in the invention, a road is expressed by a network formed by road sections among intersections, a map model is established, and a database of historical trajectories of a user is established; when the user enters a place, positioning terminal information and positional information of the user sent by a positioning terminal of the user are received, historical trajectory data of the user is acquired according to the positioning terminal information and includes the walking frequency of the user on each road section and path choices of the user at each intersection, and a path probability model is established according to the historical trajectory data so as to characterize the probability that the user selects an adjacent road section at each intersection; and a predicted trajectory of the user is obtained according to the current positional information of the user and the path probability model. The technical scheme provided by embodiments in the invention overcomes the problem that related positioning technology cannot predict the movement trajectory of the user.

Description

Technical field [0001] The present invention relates to the technical field of positioning, in particular to a method and device for predicting a positioning track. Background technique [0002] In large shopping malls or exhibition halls and other venues, merchants and exhibition units will recommend products, shops or exhibition items to users on the user's handheld navigator or positioning terminal. However, this kind of recommendation is usually fixed, and it is only a fixed list displayed to users, which is not very attractive to users and cannot play a good advertising role. On the other hand, user tours in shopping malls or exhibition halls are often weakly purposeful and random, but if they can follow the user’s actions and advertise based on the user’s actions in real time, it will be able to guide users and make it easier The promotion is successful and attract users. [0003] At this stage, handheld navigators and positioning terminals have good positioning functions, ...
