The invention discloses an intelligent body fuzzy dynamic obstacle avoidance method based on a Camshift algorithm. According to the content of the method, an intelligent body small cart obtains environmental image information of the intelligent body small cart trough a CCD camera, a DSP image processor module processes the image information, and moving target tracking and positioning are conducted through the Camshift algorithm of an OpenCV function library, dynamic obstacle coordinates are obtained and sent to a bottom layer controller module. The dynamic obstacle coordinates, the intelligent body small cart speed and three-side ultrasonic ranging information are input to a dynamic obstacle avoidance fuzzy controller, and the dynamic obstacle avoidance fuzzy controller outputs the control commands of the steering angle Psi and the speed v of the intelligent body small cart to achieve dynamic obstacle avoidance. According to the intelligent body fuzzy dynamic obstacle avoidance method, rapid target matching and positioning are achieved through the Camshift algorithm, the speed in capturing dynamic obstacles in the dynamic environment is increased, and obstacle avoidance lag or even failure caused by the fact that the speed in capturing dynamic targets is too slow is compensated.
