[0098] The specific embodiments of the present invention are given below, and the present invention is described in detail with reference to the accompanying drawings.
[0099] The present invention provides a trajectory similarity calculation method based on the geometric vector method. This part provides a detailed description of the algorithm. The description process takes the similarity between two trajectories as an example. This method can be extended to calculate multiple routes. The similarity between the two.
[0100] Such as figure 1 As shown, the present invention discloses a method for calculating the similarity of time-space trajectories, including:
[0101] Step 1. Define the distance corner rate and characterize the user's points of interest;
[0102] Step 2: Identify the user's points of interest based on the experience threshold; calculate the public points of interest based on the user's points of interest in the track;
[0103] Step 3. Calculate the similarity and d...
