一种高效的建筑物直线特征提取算法
|
摘要
随着遥感卫星的发射,国内影像处理事业逐渐被人们重视。高效、快速地对遥感及航测影像进行特征提取成为当前研究的热点。本次实验采用辽宁科技大学1∶2 000航拍影像图,针对教学用地建筑物直线提取中绿色植被和道路的影响,提出了一种新的直线提取算法。实验将直线拟合和Hough变换结合并进行改进,对实验结果进行对比,分析改进前后效果。实验结果表明:该方法能很好地适应复杂地形下建筑物的直线特征提取,提取速度快,有效地解决了教学用地中道路和绿色植被对建筑物直线提取的影响问题。
With the launch of the remote sensing satellite,the domestic image processing industry is gradually being valued by people.Efficient and fast remote sensing and aerial image feature extraction become a research hotspot. This experiment used 1∶ 2 000 aerial image map of Liaoning University of science and technology,for teaching buildings line extraction,green vegetation and road effect,a new line extraction algorithm is proposed. The experimental results are compared with the experimental results,and the results are compared with the linear fitting and the Hough transform. The experimental results show that this method can adapt to the complex terrain,the linear feature extraction of buildings,the extraction rate is fast,effective solution to the road and green vegetation in the teaching of buildings on line extraction.
