In view of the imbalance between supply and demand of drug detection dog resources caused by the long training cycle and high training cost in the traditional drug detection dog training process; Trainers face problems such as health and safety hazards and repetitive mechanical labor during their training. The physical position of the drug detection dog is located by the ultra-wideband module, and the training and supervision assistant system of the drug detection dog is designed and developed based on the moving target location and tracking algorithm. With the intelligent car controlled by Raspberry Pi as the mobile carrier, a camera is added to capture the whereabouts of drug-sniffing dogs and the video is transmitted back to the terminal in real time. In the design process, the positioning accuracy of the UWB module, the relative distance between the intelligent car and the drug detection dog and other aspects of the impact on the results need to be considered. After testing, Through the experiment test, the camera can timely and accurately track the video of drug-sniffing dogs, which ensures the positioning accuracy and improves the tracking efficiency.
