中文说明：畸变校正技术，matlab程序下载其实在opencv的calibration这个例子中完成了畸形矫正。但是我在我的工程中，由于一些条件的限制，在没有做矫正的情况下，2.8的镜头刚好照满整个触摸区域，但是经过矫正后，由于主要是径向畸变，可是opencv是校正前后图像一样大小的做法，必然导致有一部分校正后的图像被裁剪了。没办法，我只好自己去按原理写最基本的校正算法了。现在贴一些基本算法原理出来。
English Description：
Distortion correction technology, matlab program download, in fact, in the calibration of OpenCV this example to complete the deformity correction. But in my project, due to some restrictions, without correction, the 2.8 lens just covers the whole touch area. But after correction, due to the radial distortion, opencv is the same size of the image before and after correction, which will inevitably lead to the clipping of some corrected images. No way, I have to write the most basic correction algorithm according to the principle. Now paste some basic algorithm principles out.
