摘要:
 前方路面车辆的检测和跟踪是智能交通系统中的重要问题。使用单定焦相机的系统，对处于复杂环境下的车辆视野有限，远处目标的特征细节很难捕获，较宽视野区域中的特征分辨率较低；而要获得较高分辨率，就只能够缩小监控区域的视野，因此检测效果较差。为解决单定焦相机视野与分辨率之间的冲突，文中引入主-从PTZ系统加以改进。其中，主系统采用固定的广角镜头以获得较宽的视野，同时采用高清晰度的PTZ相机作为从系统，提升较宽的视野中特定目标区域的分辨率。文中提出并实现了一个主-从PTZ视觉检测软件的模块化解决方案。该方案利用主系统进行广角搜索，利用从PTZ增强特征细节。测试结果表明，该系统能够实现较宽视野中特定目标的较快检测，提高目标图像细节分辨率，改进目标特征细节检测率，同时具有简单、快速、高效、易于二次开发等优点。
Abstract:
 The detecting and tracking of vehicles on the road is an important problem in intelligent transportation system. To the vehicle in complicated environment,only using single fixed-focus camera system,the details of remote environment around the vehicle are hard to capture for limited vision,and the effect of detection is poorer for same reason. For single fixed-focus camera system,the common meth-od that could improve the details and higher resolution of remote object is focusing on a smaller vision coverage area. In order to solve the conflict between vision coverage area and resolution,the master-slave Pan/Tilt/Zoom camera system ( M-S PTZ) is introduced. The master camera with fixed wide-angle lens is used to achieve a wider field of vision,and the slave one used PTZ lens to enhance the detail of the image and improve the detection rate. A modular video detection system of master-slave PTZ is presented and implemented in this paper. The system of M-S PTZ as solution has many advantages such as faster detection for specific object under field environment,high-er resolution for specific target image,and more feature details of given target. At the same time,it is simple,rapid,efficient and easy to conduct secondary development.
