Abstract

The embodiment of the invention discloses a method and device for predicting a destination based on a position trajectory. The method comprises the steps of starting to predict the destination to be reached by a target user according to the real-time position of the target user after the change of the position of the target user is monitored. In the prediction process, different prediction algorithms are selected for prediction according to the number of the target position signaling corresponding to the target user, and when the number of the target position signaling is insufficient, the destination of the target user is predicted by referring to public position signaling, so that inaccurate prediction caused by the insufficient target position signaling is avoided. On the other hand, compared with a method for predicting the destination of the user by adopting a unified prediction method, the method has the advantages that the calculation process of prediction is simplified, the destination to be reached by the user can be predicted according to the real-time position of the user, and the timeliness of prediction is fully considered.

Description

technical field [0001] The present invention relates to the technical field of mobile communication positioning, in particular to a method and device for predicting a destination based on a position track. Background technique [0002] The destination forecast based on the user's location trajectory is mainly used to predict the destination that the user may go to in the future based on the user's current action trajectory, which can help us prepare in advance before the user arrives at the destination, so as to reasonably It can also be used in public fields such as passenger flow warning. [0003] The current methods of historical trajectory destination prediction include the destination prediction model based on traditional statistical analysis, which is calculated based on conditional probability. The Destination Prediction Model of Statistical Statistics overcomes some weaknesses of traditional statistical analysis, but at the same time it also faces the problem of sta...
