A method for identifying and compensating for missing vehicle trajectories

Abstract

The invention discloses a vehicle trajectory missing identification and compensation method. The identification method is as follows: obtaining all positioning information of the vehicle trajectory to which the target vehicle-mounted terminal belongs within a preset period of time; The time interval of the points; according to the calculated time intervals, calculate the mode; judge the time interval between each pair of adjacent positioning points and the mode * preset ratio, and determine the adjacent positioning of the target that is greater than the mode * preset ratio point; judge whether the distance between the adjacent positioning points of the target is greater than the preset distance, and if so, determine that the trajectory between the adjacent positioning points of the target is missing. The invention can accurately identify the missing track between adjacent positioning points, and automatically compensate the missing track of the vehicle, realizes the automation of the missing track and compensation of the vehicle, and improves the identification and compensation efficiency of the missing track of the vehicle.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a vehicle track missing identification and compensation method. Background technique [0002] At present, when the vehicle is driving, the vehicle-mounted terminal with a satellite positioning module can record the position coordinates of the vehicle at different times, and send the position coordinates at different times to the server, and generate a moving track by matching with the electronic map to represent However, during the driving process of the vehicle, there are often situations where the satellite positioning module of the vehicle-mounted terminal cannot receive the satellite positioning signal. For example, the satellite positioning signal of the vehicle is blocked by tall buildings, trees or tunnels, causing some road sections to fail to receive satellites. The positioning signal causes the lack of vehicle trajectory, which will lead to the generation o...

[0002] At present, when the vehicle is driving, the vehicle-mounted terminal with a satellite positioning module can record the position coordinates of the vehicle at different times, and send the position coordinates at different times to the server, and generate a moving track by matching with the electronic map to represent However, during the driving process of the vehicle, there are often situations where the satellite positioning module of the vehicle-mounted terminal cannot receive the satellite positioning signal. For example, the satellite positioning signal of the vehicle is blocked by tall buildings, trees or tunnels, causing some road sections to fail to receive satellites. The positioning signal causes the missing of the vehicle's driving trajectory, which will lead to the generation of discontinuous motion trajectory, resulting in the loss of the vehicle's driving trajectory, resulting in the inability to present an accurate motion trajectory to the user, which is not conducive to subsequent motion analysis of the vehicle's driving trajectory

The lack of existing vehicle trajectories is usually discovered by the user or operation and maintenance personnel by viewing the vehicle trajectories in the map with the naked eye, and by calling the Baidu interface for path planning, manual adjustments for unreasonable planned paths, manual trajectory compensation, and manual compensation Heavy workload and low efficiency
