| 摘 要： | 随着遥感技术的不断发展,高效、快速的遥感影像处理成为人们不断研究的热点。作为内业处理的基础,人们对影像直线特征提取的重视不断加强。本次试验采用辽宁科技大学1∶2000正射影像图,针对教学区内建筑物、绿化区和道路混合的特点,提出了一种自动识别并高效提取建筑物直线特征的算法。该算法将直线拟合和Hough变换进行结合,加入角度先验方法。试验结果表明:该算法的直线提取性能优于传统Hough变换,能很好地适应教学区域,对建筑物的识别能力、直线提取效率及精度有很大的提高。

| Abstract: | With the continuous development of remote sensing technology, efficient and fast remote sensing image processing has become a hot research topic.As the basis of internal processing, people pay more and more attention to the feature extraction.Using the 1∶2000 orthophoto map of the university of science and technology of Liaoning according to the teaching area, building area and road greening characteristics mixed, this experiment puts forward a kind of automatic recognition and extraction of building linear feature algorithm.The algorithm combines straight line fitting and Hough transform, and adds a priori method.The experimental results show that the algorithm is superior to the traditional Hough transform in line extraction, and it can well adapt to the teaching area, and has a great improvement in the recognition ability and the linear extraction efficiency of the building. |
