VB.net与MATLAB相结合下的高分辨率遥感数据房屋信息提取

High Resolution of Remote Sensing Data Houses Information Extraction by VB.net and MATLAB

高分辨率遥感图像通常是指图像的空间分辨率在10m以内的航天、航空遥感图像数据。对于具有丰富纹理特征的高空间分辨率图像,目前急迫解决的是解决的问题是怎样实现快速的提取目标信息。而房屋信息提取技术是利用高分辨率图像提取信息的一个难点。VB.net与MATLAB相结合,结合数学形态学等相关算法进行了房屋信息的提取;把VB.net与MATLAB相结合是把VB的可视化和MATLAB强大的数据处理技术相结合来实现最优处理。经实地验证,精度评价结果表明,房屋轮廓信息提取精度为:从数量上及面积上说精度在80%以上,总的错分比率较低。房屋高度信息提取精度在85%以上,研究方法是有效的。

High resolution remote sensing images generally refer to image to the spatial resolution within 10m aerospace,aviation remote sensing images. High spatial resolution image has rich delicate texture feature, it is urgent to solution the problem of how to extract the features. Houses information extraction technology is difficult hotspot in the application. Combining the VB.net and MATLAB, using mathematical morphology algorithms, combined with MATLAB and VB is mainly using the VB visualization and MATLAB powerful data processing technology to achieve the optimal combination. Based on the verification, accuracy evaluation results show that houses contour information extraction accuracy is： accuracy of the number and area is over 80%, the total rate of wrong classifications is lower. Houses highly information extraction accuracy is within the 85%. The research methods are effective.
