摘要
航拍图像的注释信息中记录着航拍中重要的成像参数,如相机类型及外方位元素等。本文针对当前倾斜航拍图像注释块分割存在的一系列问题,提出采用小波变换进行分割的改进方法,并结合数学形态学的方法进一步分割出注释块。实验证明,该方法不仅快速,而且准确,取得了良好的分割效果。
Comment information in aerial photos notes important parameters,such as camera style,elements of exterior orientation and so on.In this paper,a modified segmentation method is introduced,which makes it possible to implement segmentation of comment information in oblique aerial photos.First,decompose the image with wavelet transform.Then,segment the comment information,combining with the theory of mathematical morphology.Experiment result shows that the segmentation method is fast and precise.
