摘要
采用编码点和非编码点相结合的方法实现摄影测量中对应点匹配技术,讨论了标记点的中心亚像素定位方法、两类标记点的识别及编码标记点的解码方法.针对由于拍摄视角不同编码标记点呈椭圆形状时,解码正确率较低的问题,提出一种新的具有较高鲁棒性的解码方法.最后,实验验证了这种方法的效果.
By employing the matching technology based on combining coded points and non-coded point,we discuss the method of sub pixel reference point center location and identification of two kinds of targets point.As some shooting angle will present ellipse coded targets point which makes the accuracy low,we provide a new decode method with high robust.Finally,the experiment results prove the effect of this method.
