Human Body Tracking Technology Based on Video Beidou Linkage

Due to inaccurate positioning, there are certain limitations in the detection accuracy of the traditional human object detection and tracking technology method using ball surveillance systemin in the power field. In order to obtain higher human object positioning accuracy and detection accuracy, a human intelligent video tracking method supported by adaptive PID algorithm based on Beidou positioning is proposed. Through the operators wearing the safety helmet with Beidou positioning, the ball is installed with high-precision Beidou positioning terminal, and the spatial accurate position judgment of the operators and the video terminal is obtained. The PTZ fuzzy PID adaptive control of the ball is used to track the human body based on the relative position relationship between the operators and the video terminal, combined with the ECO-HC filtering tracking algorithm, the Beidou positioning terminal can be intelligently linked with video tracking, and the angle and focal length of the ball can be adjusted adaptively. The tracking success rate can reach $95 \%$, and the average accuracy rate can reach $92 \%$, achieving the purpose of accurate identification and dynamic tracking for operators.
