PHP百度AI的OCR图片文字识别

第一步可定要获取百度的三个东西 要到百度AI网站(http://ai.baidu.com/)去注册 然后获得 

 -const APP_ID = '请填写你的appid';

  -const API_KEY = '请填写你的API_KEY';

  -const SECRET_KEY = '请填写你的SECRET_KEY';

第二步下载SDK  

https://github.com/jankinsun/New/tree/master/OCR/character_recognition

或者使用官方的 http://ai.baidu.com/sdk 下载

第三步 然后就直接运行demo 的文件 DemoAipOcr.PHP

<?php
header("Content-type: text/html; charset=utf-8");
 
function curl($img){
 
$ch = curl_init();
$url ='http://apis.baidu.com/apistore/idlocr/ocr';//百度ocr api
$header = array(
'Content-Type:application/x-www-form-urlencoded',
'apikey:69c2ace1ef297ce88869f0751cb1b618',
);
 
$data_temp = file_get_contents($img);
$data_temp = urlencode(base64_encode($data_temp));
//封装必要参数
$data ="fromdevice=pc&clientip=127.0.0.1&detecttype=LocateRecognize&languagetype=CHN_ENG&imagetype=1&image=".$data_temp;
curl_setopt($ch, CURLOPT_HTTPHEADER , $header);// 添加apikey到header
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);// 添加参数
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch , CURLOPT_URL , $url);// 执行HTTP请求
$res = curl_exec($ch);
if($res === FALSE){
echo "cURL Error: ". curl_error($ch);
}
curl_close($ch);
$temp_var = json_decode($res,true);
return $temp_var;
 
}
 
$wordArr = curl('4.jpg');
if($wordArr['errNum']==0){
var_dump($wordArr);
}else{
echo "识别出错:".$wordArr["errMsg"];
}
