双通道近地遥感图像采集处理系统（Development of a Two-channel Platform for Acquiring and Processing Near-ground Remote Sensing Images）
近地遥感 多光谱相机 图像分割
2009/11/3
利用2-CCD多光谱相机设计了近地遥感图像采集平台，同步获取小范围区域作物的可见光和NIR图像，通过图像处理技术从作物图像获得反射光谱信息。采集平台包括一个2-CCD多光谱相机，两个采集盒，一台具有两个千兆网口的田间计算机。图像处理部分通过2G-R-B灰度化、中值滤波和Otsu二值化，从背景中分割出作物图像，结合作物原始R分量灰度图像，提取出作物红光图像平均灰度值，利用建立的灰度值与反射率的线性模...
