The ACM team is planning to ask for a special room for the school. But in order to prevent it from becoming a public room, FL recommends the use of credit card entry method, she designed a bar code, each corresponding to one. The bar code of this size 2*n is composed of the following three elements: 1*2, 2*1, 2*2 rectangular squares. But we also know that many people are prone to reverse the position of cards when they swipe. In order to avoid machine error handling, we think that the two barcod

This allows you to calculate the aspect ratio of the symbol to determine whether it is a rectangle or a square. Finally, the same as the QR code, using Samplegrid for the perspective transformation and sampling transformation, the original image of the symbol image correction, transformation for us to decode the required rules, in the module of the symbol matrix.
