【摘要】 提出一种提取航拍图像中线特征的方法。首先利用canny算子检测出图像的边缘,再利用改进的层进式hough变换对得到的边缘图提取线特征。仿真表明该方法能有效地提取出目标的线特征,有利于目标的准确识别。更多还原

【Abstract】 This paper propose a method to detect line feautures in areal images. First acquire the image’s edge via canny method , then apply the modified hierarchical hough transform to extract line features form edge images. Simulate results demonstrate this method is effective to extract line features and in favor of precise recognition of target.更多还原
