摘要 文章提出了一种直线段匹配的新方法。首先用直线段的梯度方向、梯度大小、长度和中点位置进行粗匹配;然后提取直线段中点的局部梯度信息,并形成中点描述符用于对直线段进行精确匹配;最后用人工图像和真实图像进行了实验。 This paper presents a new algorithm for matching straight line segment.Firstly,it uses line gradient direction,gradient size,line segment length and midpoint location for roughly matching,and then extracts the line segment midpoint of the local gradient information to create a Mid-point descriptor to match accurately,finally uses artificial image and real image to do the experiments.
