摘要
以往的直线段匹配算法都是利用直线段之间位置顺序的限制条件 ,而基于支持区域[1,2 ]的直线段匹配算法则充分利用了图像本身提供的灰度信息。每条直线段的支持区域为直线段提供几何和灰度的特性值 ,这些特性可以通过加权作为匹配度计算的一部分。使用支持区域 ,直线段的匹配更客观、准确。
To match straight line, people frequently exploit only the order constraint conditions in most of their matching algorithms. But the matching algorithm based on line support region is different from the previous ones, for it exploits the gray level information contained in the image. From every straight line's support region, some geometry and intensity properties are got to uniquely describe the straight line. These properties can be combined to the matching evaluation function using weighted summation. They make the matching more objective and accurate. \;
