实现的内容

该程序可以实现图片的二维码定位，其主要运用的原理是通过二值化和opencv自带的轮廓筛选功能在图片中找到二维码的位置，然后利用向量知识通过三角形将二维码的位置进行矫正。
The program can locate the QRcode in a picture. Its main principle is using binarization and the opencv-contour-selection function to find the position of QRcode in the picture, and then rectify the position of the qrcode by using vector knowledge through triangles.
