摘　　要：设计了一种超声电机驱动的目标视觉跟踪系统。该系统通过对摄像头采集到的图像进行处理,对目标进行识别、提取其位置信息,在此基础上,利用模糊—PID控制方法经超声电机控制摄像头的偏转角对目标进行实时跟踪。实验结果表明:对超声电机采用这种复合控制的方法可以使跟踪系统获得较好的控制性能,其跟踪的快速性达到约0.2 s,精度在±6mm以内。A visual tracking system driven by ultrasonic motors is designed. The image from video camera is processed and the target is identified. The system can track the target by fuzzy-PID control method in real time, through the feedback of its position information. Experiment results show that the compound control method applied to ultrasonic motors can make the tracking system have good performance. Its rapidity is within 0.2 s and position precision can be implemented within ±6 ram.
