遥感影像中阴影检测应用

Shadow detection in remote sensing images

本研究通过对现有阴影探测算法的比较,对左权县土地确权过程中航空遥感影像上的阴影区域进行了研究。我们采用基于HSV-C1C2C3彩色模型的算法研发阴影探测,经过验证发现它的探测效果是非常出色的。我们开发了基于MATLAB的Shadown识别软件,并在此基础上加以完善。研究结果对地物的正确识别、土地权属界限的准确划定及植被研究等具有重要的意义。

In the process of land ownership confirmation in Zuoquan County,a shadow detection algorithm based on HSV-C1C2C3 color model is proposed for the shadow regionon the aerial remote sensing image through a comparative study of existing shadow detection algorithms,which has a good shadow detection effect after testing.The shadow recognition software is developed using MATLAB as its foundation.The research results are of great significance to the correct identification of ground objects,the accurate demarcation of land ownership boundaries and the study of vegetation.
