摘　　要：视频监控作为一种传统视频技术与现代通信技术相结合的应用,目前在国内外已引起了越来越多的关注,文中用两台行波型超声电机作为云台监视器的驱动部件实现平扫俯仰两个自由度转动,用VC++开发的程序对摄像头捕获的图像进行处理,识别目标,并基本上解决了多目标存在时,目标的选择和跟踪。由于超声电机与电磁电机相比具有低速大转矩,响应快,定位精度高,断电自锁等特点,因此可直接驱动,无需减速装置,系统结构简单紧凑。Intelligent video surveillance system is the combination application of the traditional video and the modern communication technology, and has aroused increasing attention at home and aboard. The pan-tih can rotate in horizontal and vertical directions by using two ultrasonic motors served as the driving units. The program developed with Visual C＋＋ processes the images captured by a camera, and recognizes the moving target. It also partly solves the multi-target problem. Compared with electromagnetic motor, the ultrasonic motor has advantages Of high torque at low speed, quick response, high precision and self-locked, which makes the structure simpler and control more convenient.
