用BMP图像文件合成多光谱遥感图像的简单方法

叙述了多光谱遥感数据转化为位图(BMP)格式彩色遥感图像的简单方法。由于遥感数据的记录格式与BMP图像的数据记录格式具有极其相似之处,二者均以像元为记录单位,遥感像元记录的是地物的多光谱数据,BMP图像的像元记录的是该像元的RGB三基色值,将多光谱遥感数据转化为BMP像元的RGB数据格式,并写入图像文件中即可获得BMP格式的彩色遥感图像。文中给出了BMP图像文件的详细结构,并利用三通道海洋水色CCD成像仪预研样机航空飞行实验中获得的遥感数据,叙述了将遥感数据转化为BMP图像的详细过程,并获取了清晰的BMP格式遥感图像。

Simple Method to ComposeMulti-spectral Remote Sensing Data Using BMP Image File

The paper describes a simple method to convert multi spectal remote sensing data into Bit Map Picture (BMP) image. There is a striking similarity between the recording format of multi spectral remote sensing data and that of BMP image, both them have the similar recording unit, that is pixel; the pixels in the remote sensing record the multi spectal data of ground objects while the pixels in BMP image record the brightness value of RGB components of the pixels. Converting the multi spectral remote sensing data into BMP format and writing them into the BMP file, a piece of BMP image will be obtained. This paper gives out the detailed information about the BMP image file, and relates the procedure to convert multi spectral data into BMP images with the remote sensing data acquired from the flight of Ocean Color CCD Imager. Many pieces of clear remote sensing pictures have been obtained.
