Embodiment Construction
[0034] The present invention will be further described below in conjunction with the examples. The description of the following examples is provided only to aid the understanding of the present invention. It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, some improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
[0035] One, overall thought of the present invention:
[0036] The similarity measurement model of the present invention is mainly based on an integrated point sequence data set collected by vehicle coordinates, which is divided into a test set and a label set, and a similarity attribute is calculated for each trajectory in the test set and the label set. Lagrangian interpolation method is used to fit polynomial curves to maximize the display of trajectory charac...
