PHP: OCR Text Recognition Based on Baidu brain api,

There is a project that uses text recognition. I found a lot of information on the Internet, and the results were not very good. By chance, I came into contact with Baidu brain. Baidu brain provides many solutions, one of which is text recognition. Baidu provides three types of Text Recognition: bank card recognition, ID card recognition, and general text recognition. Let's test them.

Step 1: Download the PHP text recognition demo

: Https://git.oschina.net/jianqingwang/ocr

Step 2: apply for an api

Go to Baidu brain https://ai.baidu.com/tech/ocr/generalapplication API

Baidu brain application api

After the application is completed, create an application and obtain two pieces of information: AppID, API Key, and Secret Key.

Open DemoAipOcr. php In demo. Let's configure the interface information together!

<? Php // introduce the OCR SDKrequire_once '.. /AipOcr. php '; // define the constant const APP_ID = 'Write your id'; const API_KEY = 'Write your key'; const SECRET_KEY = 'Write your secret_key '; // initialize $ aipOcr = new AipOcr (APP_ID, API_KEY, SECRET_KEY); // ID card recognition // var_dump ($ aipOcr-> idcard(file_get_contents('idcard.jpg '), true )); // bank card recognition // var_dump ($ aipOcr-> bankcard(file_get_contents('bankcard.jpg '); // general text recognition $ rescult = $ aipOcr-> comment ')); $ words = $ rescult ['words _ result']; var_dump ($ words [0]); // var_dump ($ aipOcr-> general(file_get_contents('20170413195205.jpg ')));

The preceding three identification systems are shown. You only need to test the comments on the methods for canceling bank card recognition and ID card recognition.

Let's take a look at the recognition effects of my images 20170413195205.jpg:
