Design of High-precision Positioning System for Moving Target Tracking Based on Ultra Wideband Technology
To overcome the low tracking and positioning accuracy caused by moving targets,a high-precision positioning system for moving target tracking based on ultra wideband technology is designed.The image acquisition module consists of an FPGA unit,VGA display unit,frame buffer unit,and image acquisition unit,which achieves image acquisition in moving object tracking and posi-tioning.In the ultra wideband technology module,it designs the antenna,positioning base station,and mobile node for the ultra wide-band moving object positioning,completes the ultra wideband dynamic networking,and achieves the hardware design of the system.The collected images of the hardware system are implemented the image graying processing and morphological filtering processing to enhance the useful information in the image,and design the tracking algorithm of the TLD moving target.With the target moving,the TLD model will continuously learn the tracking moving target,obtain the target changes in the distance,depth of field,angle and other levels,and continuously learn and identify to achieve good tracking results,the dynamic positioning algorithm for moving tar-gets based on ultra wideband technology is adopted to achieve the high-precision positioning for moving targets based on the tracking results,and complete the software design of the system.The experimental results show that the tracking error rates of the system in medium and long distance target tracking and positioning experiments are below 0.60％and 2.4％,and the positioning error at the corner of the route is relatively low when moving along the S-shape,which is in line with the flight path of the experimental moving target,and it has a good positioning ability.
