Title The design of video tracking software based on DSP
Abstract Video tracking technology is a hot research issue in the field of computer vision, tracking system based on DSP has been widely used in intelligent monitoring, fire control, and other fields. In this paper, based on the DSP video tracking software, including video target tracking algorithm design and DSP software development, implementation of algorithm transplantation. First of all, design tracking method in the Matlab environment, for a single target ground environment, through the gate detection, three frame difference detection and morphological processing to achieve target detection, through the correlation tracking and location prediction,realizing the target tracking simulation results show the effectiveness of this method. Secondly,programming DSP in the environment of CCS, we optimized the correlation algorithm, realized the application of algorithm transplantation. Set up a test environment in the laboratory,the hardware platform using TMS320DM642 chip-based processor board for ground target tracking experiment, the results show that the system can better achieve its objectives stable and accurate tracking.

1.1 研究背景和意义
目标检测跟踪是在二维图像处理技术基础上发展起来的,它是图像处理和计算机视觉领域中的一个非常活跃的分支,它的基本任务是利用运动物体的图像序列来分析物体的运动情况。运动目标检测和跟踪在许多领域有着广泛的应用,在军事上,有空载下视系统,如对低空及地面目标的监视,低空或地面系统,如空中目标的检测与跟踪等;在民用上,常与报警系统协力完成侵入目标的检测与跟踪[1]。
