Research On Human Motion Trajectory Tracking and Positioning Technology from the Perspective of Safety Monitoring

Background: Displacement racing can improve human motor function and promote mental health. This kind of sports has the characteristics of long path, complex environment and long activity time. When participating in such sports, it is easy to have unexpected injuries, sudden diseases or deterioration of the natural environment. At this time, safety monitoring is particularly important.Subjects and Methods: This paper aims at the problem of tracking and positioning of motion trajectory in displacement race sports, a human motion trajectory tracking and positioning method based on DBSCAN clustering is proposed. The method includes three basic steps: obtaining GPS trajectory coordinates, DBSCAN clustering filtering, and geometric algorithm data compression.Conclusions: The final experimental results show that the method is effective for the tracking and positioning of human motion trajectories in displacement racing sports, and can accurately retain useful data points in the positioning process, reflecting the superiority of the algorithm.
