Based on the tesseract of open source, we made an identity card recognition app.Picture Resources is Baidu looking for, and mobile phone to the computer screen to take pictures, shoot a lot of patterns, the impact is relatively large, so the error is not small, measured on their own identity card photo will be much better.：1.
