Design and Implementation of Video Target Tracking Based on TMS320DM642 Chip[JZ)][HS)]

摘要:

运动目标的检测与跟踪一直是在计算机视觉的研究领域占有重要位置,该技术被越来越广泛的应用到交通管理、军事、公共安全监控等领域中;文章主要研究基于TMS320DM642开发平台的视频运动物体目标的检测与跟踪,文章分为软硬件两部分进行设计,硬件部分主要包含视频采集模块、视频处理模块以及显示模块3个部分,通过CCD摄像头采集视频信号,接着将采集的模拟视频信号传输到SEED VPM642视频处理模块,在VPM642中通过高性能视频解码器TVP5150将模拟视频信号转换成BT.656格式的视频信号,并将该信号传输给DM642的视频接口；在系统软件部分,系统采用TI的DSP集成开发环境CCS2.2作为系统软件开发平台,最终在DM642视频图像处理平台上实现运动目标的实时检测与跟踪;实验结果表明,该文提出的算法移植和优化方法效果明显,可以在DSP开发平台上实现运动目标的实时检测与跟踪。

Abstract:

the detection and tracking of moving targets always occupies an important position in the research field of computer vision, the technology has been applied to traffic management, military, public safety monitoring and other fields more and more widely. This paper focuses on the detection and tracking of the target video motion object based on TMS320DM642 development platform, this paper is divided into two parts of hardware and software design, the hardware part mainly includes video acquisition module, video processing module and display module three part, through the CCD camera capture video signal, then the acquisition of the analog video signal to the SEED VPM642 video processing module, the high performance video decoder TVP5150 transform analog video signal into a video signal in BT.656 format in VPM642, and transmits the signal to the video interface of DM642; in the system software, system uses the TI DSP integrated development environment CCS2.2 as a software development platform, real-time detection and tracking of moving object in the final realization of DM642 video processing platform.
