Embodiment Construction
[0035] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0036] An embodiment of the present invention provides a vehicle driving route correction method in the case of lack of road network data, the specific application of the method is as follows figure 1 As shown, the GPS system on the vehicle will collect the track points of the vehicle when it is driving on the target road. Each track point information on the driving track is sent to the server. After receiving all the track point information of the driving track, the server executes the vehicle driving route correction method in the case of missing road network data to judge the navigation mileage in the navigation software. Whether it is accurate, if accurate, the navigation route is the driving route of the vehicle, if not accurate, the driving route is corrected.
[0037] It should be noted that the GPS system inc...

The invention provides a vehicle driving route correction method and system under a road network data missing condition. The method comprises the following steps: acquiring track point information of a vehicle driving track; calculating the maximum driving distance between every two adjacent track points in sequence according to the track point information; and comparing the maximum driving distance with the navigation mileage between the corresponding two adjacent track points, and if the maximum driving distance is not greater than the navigation mileage between the two adjacent track points, taking a connecting line of the two adjacent track points as a driving route between the two points. According to the method, the maximum driving distance between two adjacent track points is calculated according to the track point information, and the maximum driving distance is compared with the navigation mileage between the two track points, so that whether the navigation mileage between the two track points is accurate or not is judged, and further a navigation route or connecting line of the two tracks is taken as a final driving route. Compared with the prior art, the method has the advantages that a more reasonable value is obtained through theoretical calculation to serve as a judgment standard instead of guess, so that the judgment accuracy is improved.
Description
technical field [0001] The invention relates to the field of traffic technology, in particular to a vehicle driving route correction method and system in the case of missing road network data. Background technique [0002] Due to the drift of the mobile device, the GPS track points of the truck will deviate from the electronic map data, and the track points will not completely follow the arrangement of the road data coordinates. Therefore, track matching is required to match the track points to nearby roads. Selecting an appropriate road sequence constitutes the basis of matching, and high-quality road network data can provide highly reliable data for truck trajectory analysis. After obtaining the road data around the track point, the specific matching roads are selected through some relatively mature algorithms. These algorithms include spatiotemporal analysis, probability-based analysis models, etc., and can obtain better matching results. [0003] However, limited by the...
