摘要
利用可视化编程语言ＶＢ开发出一套成像光谱仪资料处理系统，用于海面叶绿素浓度信息提取，具有操作方便的图形用户界面，大大简化了各种操作，特别省去了众多参数值的反复输入。该系统的成像光谱仪资料信息提取包括大气校正模式、几何校正模式、叶绿素浓度信息提取模式三部分，同时，系统具有图像格式转换、图像处理、图像浏览和结果演示等功能。图像格式转换可把其它格式图像转换成ＢＭＰ格式，图像浏览可快速显示和检查成像光谱仪各波段图像，结果演示功能可自动连续显示演示文件中的图像文件，可快速增加、删除、修改图像文件名。图像处理模块可加入许多常用的图像处理功能，并可调入一些商业化软件。
A data processing system was developed with the visual Basic for Windows,Which is used to derive chlorophyll concentrations from imaging spectrometer data.It has a user-friendly graphic interface.All operations,especially the procedure of inputing a number of parameter values,are very handy.Three procedures to derive chlorophyll concentrations are atmospheric correction,geometric correction and chlorophyll concentration extraction.Other functions such as data format transformation,image processing,image browse,and demonstration are very helpful to inspect the results.Format transformation function is used to convert other image formats into BMP format which is popular in Windows.Browse can quickly display the band images of imaging spectrometer.Demonstration can continually display all images in the demo files.It is very esay to add,delete or modify the contents of the demo files.The part of image processing includes some image processing functions such as enhancement,histogram equalization,etc.It can also call some famous image processing softwares such as photostyler to do image processing.
