主要功能是实现相机标定，以及实现反投误差，实现特征点的提前。(The main function is to achieve camera calibration and error to achieve the anti-investment, to achieve the feature points in advance.)

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

轮轨接触CONTACT程序，可以用来计算轮轨磨耗(Wheel-rail contact CONTACT procedures can be used to calculate the wheel-rail wear)

在对话框中实现splitter(achieve splitter)

本解码器类支持普通jpeg文件格式，这也是目前大多数jpeg文件所采用的格式，此格式主要特点是数据精度为8位，采用Huffman编码的普通DCT帧（不支持扩展串行和递进模式及数学编码）。本解码器类的 IDCT算法采用三种模式，分别是浮点解码、定点整数解码和定点整数MMX优化解码，您可根据具体情况选择。(The decoder class support common JPEG file format, which is currently the most JPEG files in the format and the main characteristics of this format is data for 8-bit precision, using Huffman coding DCT common frame (does not support extended serial and progressive model and arithmetic coding). The decoder of the IDCT algorithm uses three modes, respectively, floating-point decoding, fixed-point integer decoding and fixed-point integer MMX optimization, you can choose according to the specific circumstances.)

水表指针识别系统，能够从外部导入任何一个bmp图像，最好是水表图，能够对该图形操作并读出图中水表的度数 (meter target identification system from the outside into any one bmp image, preferably meter map, Graphics to be able to operate and read out the map meter reading)

说明：  计算凸包面积，点集Q的凸包是指一个最小凸多边形，满足Q中的点或者在多边形边上或者在其内。(Calculate convex hull area。The convex hull of point set Q is a minimum convex polygon, to meet the Q of the point or polygon or in its inside edge)

实现窗口的显示以百叶窗的形式出现的精美程序(To achieve the display window to the blinds in the form of fine program)

空间点云的三角化，已通过调试，大家共同学习(Point cloud of the triangular space, and have passed testing, we learn together)

图像的纹理分析应用实例,做图像处理的同志们可以参考一下哟(image texture analysis application examples and do image processing comrades can make reference to yo)
