摘要:

受限于硬件资源,SAD加速器只能实现较小图像的匹配。本文提出了一种高分辨率图像匹配算法,将较大图像的匹配拆分成SAD加速器支持的基本计算粒度,同时保证匹配精度和实现效率。并将该算法应用到二级金字塔算法中,取得了较好的效果。

Abstract:

Restricted to hardware resources, the SAD accelerator can only realize the matching of small images. This paper proposes an algorithm of matching high resolution images. This algorithm divides high resolution images to base granularity computation blocks. This algorithm has good matching precision and efficiency, and it is applied into the twograde pyramid algorithms, and gets a good result.
