基于达芬奇平台DM6467运动目标检测的研究与实现

DaVinci DM6467 Platform Based on Motion Target Detection

在智能视频监控领域,TI的Davinci(达芬奇技术)系列双核(ARM+DSP)处理器发挥了重要的作用。提出基于达芬奇平台DM6467的运动目标检测系统的研究与实现。其中ARM核负责应用程序接口,多线程调度;DSP核则负责运动目标检测算法的处理。运动目标检测算法采用帧间差分法,首先对图像进行预处理、二值化,然后通过配置TI的Codec Engine(算法引擎),实现算法的移植。实验结果表明,在基于Davinci技术的DM6467平台下,ARM核和DSP核协调运行效果良好,能够实时采集视频图像并实现运动目标的检测。

This paper presents the research and implementation of moving object detection system based on the DaVinci platform DM6467.The ARM core is responsible for the interface of application program,multi thread scheduling,while,DSP core is responsible for processing of target detection algorithm.Moving object detection algorithm employ the inter frame difference method,conduct preprocessing and binaryzation for the images,and then realize the algorithm transplantation through the configuration of the TI Codec Engine（algorithm engine）.
