Embodiment Construction
[0052] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0053] figure 2 It is a schematic flowchart of a vehicle travel trajectory analysis method provided in the embodiment of the present application. The method can be applied to a terminal or a server. like figure 2 As shown, the method includes:
[0054] Step 201 , acquiring the travel data of the target travel of the vehicle.
[0055] The travel data includes a plurality of position information corresponding to a plurality of travel track points and a plurality of collection moments corresponding to a plurality of travel track points, and the plurality of travel track points include the start point of the target travel, the end point of the target travel, and the target travel The n intermediate track points of , the start p...

The application discloses a vehicle travel trajectory analysis method and device, and a computer storage medium, which belong to the technical field of vehicle electronics. The method includes: acquiring travel data of a target travel of the vehicle, and then determining m target track points among n intermediate track points based on the travel data. Since each target trajectory point satisfies: the variation trend of the distance to the target line before the target collection time corresponding to the target trajectory point is different from the variation trend of the distance to the target line after the target collection time. Therefore, the present application The target trajectory points obtained in the above can include the travel trajectory point farthest from the starting point and the end point of the target stroke, and other travel trajectory points that meet the conditions, which improves the flexibility of obtaining the key points of the journey.
Description
technical field [0001] The present application relates to the technical field of vehicle electronics, in particular to a method and device for analyzing a vehicle travel trajectory, and a computer storage medium. Background technique [0002] At present, the proportion of driving vehicles in various travel modes is increasing. During one trip of the vehicle, the historical trip matching the current trip can be obtained according to the trip data of the vehicle, and the destination of the historical trip can be predicted as the destination of the current trip. At present, the key points of the itinerary are usually extracted from the itinerary data, and by comparing whether the key points of the itinerary in the current itinerary trajectory are the same as those in the historical itinerary trajectory, it is determined whether the current itinerary matches the historical itinerary. [0003] In the related art, the travel trajectory point with the largest distance to the line ...
