Abstract

The invention relates to the technical field of vehicle trajectory data simulation, in particular to a trajectory data simulation method and device. The trajectory data simulation method comprises thesteps: obtaining preset number information, start-stop longitude and latitude, start-stop time and start mileage; acquiring trajectory data based on the start-stop longitude and latitude, wherein thetrajectory data comprises a total mileage and point location information of all point locations contained in the total mileage; calculating mileage information of each point location according to theinitial mileage, the total mileage and the point location information; configuring a row key for each point location according to the number information, the starting and ending time and the point location information; and correspondingly storing the row key of the point location, the point location information of the point location and the mileage information of the point location. According tothe trajectory data simulation method, the trajectory data can be automatically acquired according to the preset information of the to-be-simulated point locations, and the trajectory data is insertedinto the corresponding Hbase table, so that the data manufacturing efficiency and cost are improved.

Description

technical field [0001] The invention relates to the technical field of vehicle track data simulation, in particular to a track data simulation method and device. Background technique [0002] For the current online car-hailing, express delivery, take-out and other related industries that involve route planning, track playback and other related businesses, when related business changes, relevant track data is needed as the data basis to verify whether the functions of the corresponding modules are correct or whether the rules are correct or not . Vehicle / mobile phone trajectory data is generally stored in the big data Hbase, which is convenient for unified management, query and analysis. It will be frequently used when the offline environment needs to use trajectory playback, trajectory simulation or auxiliary testing, and can quickly generate trajectory information, which greatly reduces the time for verifying track-related functions in the offline environment. [0003] Si...
