Situation Replay Method Based on Trajectory Segmentation Pre-creation
Situation replay is an important means for researchers to analyze and find problems.The current situation replay system reads and processes a large amount of data when the user drags the timeline,the system response time is increased,and the development of the review is affected.Aimed at the above problems,the technology of trajectory data reading and display for situation replay is stud-ied,and a situation replay method based on trajectory segmentation pre-creation is proposed.Firstly,a trajectory compression algorithm with target motion state recognition is used to compress the target trajectory.Then,based on the theory of trajectory precreation,the compressed target trajectory is pre-created into N-segment trajectories.Finally,the target position is calculated in real-time according to the current time and motion state information,and the target trajectory is updated.The experimental results show that the method can improve the average response speed of the situation replay system,and the method is feasible and effective.
