本代码主要关于摄影测量中的单向空间后方交会(resection of photogrammetry)

说明：  基于信息熵进行图像质量评价，评价图像质量好坏。流程简单易于操作(Image quality evaluation based on information entropy)

利用opencv基于灰度投影算法进行图像平移补偿(Use opencv gray projection algorithm for image translational compensation)

考虑雨衰 阴影 和多径影响，可以广泛的应用于数据预测及数据分析,采用了小波去噪的思想。( Consider shadow rain attenuation and multipath effects Can be widely used in data analysis and forecast data, Using wavelet denoising thought.)

JPEG2000自己编写的代码，与标准版有所不同，里面有详细注释，可以运行(Own code JPEG2000 Standard Edition is different, there are detailed notes, you can run)

深度搜索算法用于一幅二值图像，指定开始点和目标点(deep first search method is used for binary image,with assigned start and end point)

基于ESS303开发板的OV7670_VGA拍照功能实现(Implementation of OV7670_VGA camera function based on ESS303 development board)
