摘要:: 利用交通现场俯视摄影图可快速准确记录事故现场信息,再通过计算机分析处理,对事故现场勘查、责任划分具有重要意义。然而对事故现场俯视摄影图进行几何校正后,单幅图像存在视场角度小、局部场景信息量少的缺点,需要对多幅图像进行拼接得到更多图像信息。因此首先提出分阶段快速网格匹配方法,实现多幅有部分重叠图像的快速匹配,接着提出一种快速图像融合方法,实现多幅图像无缝融合,最后以例证的方式证明了该方法的有效性及良好的鲁棒性,很好地满足了交通现场较大信息容量的图像分析处理要求

Abstract:: Using traffic scene overlooking photography diagram can rapidly and accurately record the information,and through software image processing,it has very important significance for accident analysis and the division of responsibilities.And the scene of the overlook photography diagram after geometry correction,singles image exist field of view small,local scene has less information shortcomings,so it needs image mosaic to get more field information.Therefore,it first proposes fast grid matching phases,there is some overlap multiple images to achieve the rapid matching,and then proposes a fast image fusion method,to achieve seamless integration of multiple images,the last example of a way to prove the robustness of the method is validity and good.It＇s a very good method to meet the large volume of traffic on-site image analysis and processing requirements
