摘　　要：针对传统视频图像跟踪监控系统准确率低的问题,引入目标检测技术,设计一种新的视频图像跟踪监控系统。利用DSP+FPGA构成硬件的核心部分,通过Camera Link,HD-SDI输入接口将视频信号转换为FPGA能够识别的TTL电平信号,应用驱动伺服技术实现目标的稳定跟踪,重点设计了图像输入采集模块和图像处理模块。在硬件平台上设计了软件相关算法,通过双边滤波和跟踪算法实现软件编程。为检测跟踪监控系统效果,与传统系统进行实验对比,结果表明,设计的系统能够更加准确地定位出目标图像,即使在复杂背景下也能够稳定地跟踪目标,实时性高,采集能力强。In view of the low accuracy of the traditional video image tracking and monitoring system,a new video image tracking and monitoring system is designed by introducing target detection technology. In the system,DSP + FPGA is used to construct the core part of the hardware,the input interfaces of Camera Link and HD-SDI are used to convert the video signals into TTL level signals that FPGA can recognize,the drive servo technology is used to achieve stable tracking of the targets,and the image input acquisition module and image processing module are mainly designed. The software related algorithms are designed on the hardware platform. The bilateral filtering algorithm and tracking algorithm are used to achieve the software programming. In order to detect the effect of the tracking and monitoring system,contrastive experiments are performed between the designed system and the traditional system. The results show that the designed system can locate the target image more accurately,and can stably track the target even in a complex background. In addition,it is of excellent real-time performance and powerful acquisition capability.
