Title:
VEHICLE DRIVING TRAJECTORY MONITORING METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/099480
Kind Code:
A1
Abstract:
A vehicle driving trajectory monitoring method and system; when a vehicle starts a new journey, acquiring the geographical coordinates of the starting point and the geographical coordinates of the end point of the journey; respectively converting same into starting point grid coordinates and end point grid coordinates; finding in a grid trajectory database a trajectory set of all the historical trajectories comprising said starting point grid coordinates and said end point grid coordinates; during the journey process, sampling the geographical coordinates of the current position of the vehicle, and converting same into sample point grid coordinates; removing the historical trajectories in the trajectory set corresponding to the last sample point grid coordinates of the vehicle that do not comprise the current sample point grid coordinates, in order to obtain a trajectory set corresponding to the current sample point grid coordinates; and, on the basis of said trajectory set and the trajectory set corresponding to the last sample point, calculating a degree of support of the current sample point and comparing same with a preset degree of support threshold in order to determine whether the current sample point is abnormal. The present monitoring method maintains good recognition effects of abnormal trajectories, and has a short response time and high degree of accuracy.
