In different service scenes, the acquisition time is different, and in the process of developing and debugging a trajectory algorithm, the longer the time is, the greater the data size is, the greater the difficulty in debugging the position information is, so that a method is needed for improving the efficiency of debugging and verifying the algorithm.
At present, the trace algorithm debugging in the field of sports and trip is generally implemented by collecting original data and importing the data into software to modify debugging and verification algorithms. The method for collecting original position information data and importing the original position information data into software is generally called track playback, and if the collection time is long, the algorithm debugging and verification takes a long time and the efficiency is low.
