摘要:

为满足嵌入式图像处理的需求,提出了嵌入式图像处理的程序移植方法。以OPENCV中的混合高斯背景建模函数为例,基于TI的达芬奇DM3730硬件平台,阐述了在不影响程序结果的基础上,对算法进行移植加速的方法。主要包括程序主体的处理,以及定点化等,在DM3730目标平台上实现了混合高斯模型事实实现动态提取的方法。结果表明,该方法可满足基本应用需求,能使用该方法对浮点算法进行定点DSP移植,并可广泛应用于各种图像处理算法之中。

Abstract:

A transplant method is proposed for timely image processing.A successful mixed Gauss background modeling in OPENCV and the TI DAVINCE DM3730 platform is given to show how to transplant and accelerate the algorithm without affecting the result,covering the fixed point of the algorithm and dealing with the code structure.The experimental results illustrate that this method can satisfy the need of application,and can be used in the floating to fixed point transplantation and in most of the image processing algorithm.
