不知不觉手写文字识别百度已经开始邀测了。需要的小伙伴去申请了哦。申请方式加入文字识别群找PM。或者工单提交申请。都要说明自己的APPID哦。

手写文字识别-示例代码

import java.net.URLEncoder;

import com.baidu.aip.util.Base64Util;
import com.xiaoshuai.baidu.util.FileUtil;
import com.xiaoshuai.baidu.util.HttpUtil;

/**
* @author 小帅丶
* @类名称  HandWriteTest

*/
public class HandWriteTest {
public static void main(String[] args) throws Exception {
String url = "https://aip.baidubce.com/rest/2.0/ocr/v1/handwriting";
String accessToken = "自己的access_token";
byte[] imageData = FileUtil.readFileByBytes("C:/Users/Administrator/Desktop/xs.jpg");
String img64 = Base64Util.encode(imageData);
String param ="image="+URLEncoder.encode(img64,"UTF-8");
System.out.println("请求的参数:"+param);
String object = HttpUtil.post(url, accessToken, param);
System.out.println(new String(object));
}
}

手写文字识别-返回的JSON字符串(全部内容)
因为文档还没有。不太确定参数是什么。默认只传递到了image参数。会对图片上的横线也做了识别。

手写文字识别-返回的JSON字符串(图片文字内容)

{
"log_id": 8502255431261250000,
"words_result_num": 11,
"words_result": [
{
"location": {

手写文字识别-测试图片

是不是发现识别还是蛮不错的。相当准确。当然前提是作者写的字不错了。哈哈。

过于潦草的也进行了测试。准确率在75%左右

这周我的小程序也争取更新加入手写文字识别功能，敬请期待。
