需求
最近要做保单识别,调研了下很多收费的服务,本着开源的精神,打算使用开源tesseract来做个服务。使用JAVA+IDEA+MACOS开发;
安装tesseract
- 执行
brew reinstall tesseract - 验证
tesseract --version
显示
安装成功!
下载中文库
- 下载中文训练库
- 放到/usr/local/share/tessdata目录下
测试图片识别
执行tesseract 图片地址 输出文件 -l chi_sim
在生成的解析文件中可以看到识别结果;
引用maven包
net.sourceforge.tess4j
tess4j
5.2.1
编写java样例
package com.hiklife.server.util;
import net.sourceforge.tess4j.ITesseract;
import net.sourceforge.tess4j.Tesseract;
import java.io.File;
/**
* @program: device-manager
* @description: 图片文字识别
* @author: HuiZhong
* @create: 2022-06-27 10:37
**/
public class OCRUtils {
public static String DATA_PATH;
public static String DEFAULT_LANG;
/**
* 根据图片文件进行识别
*
* @param imageFile 图片文件
* @param lang 指定语言库
* @return 识别文本信息
*/
public static String doOCRFromFile(File imageFile, String lang) throws Exception {
ITesseract instance = new Tesseract();
instance.setDatapath(DATA_PATH); //指定语言库目录
instance.setTessVariable("user_defined_dpi", "300");
instance.setLanguage(lang);
String result = instance.doOCR(imageFile);
return result;
}
/**
* main method
*/
public static void main(String[] args) {
//SpringApplication.run(OxOcrApp.class, args); //测试不用启用springboot
System.out.println("OxOcrApp 已启动");
try {
//设置训练库的位置
OCRUtils.DATA_PATH="/usr/local/share/tessdata/";
OCRUtils.DEFAULT_LANG="chi_sim"; //eng ：英文 chi_sim ：简体中文
String ocrText = OCRUtils.doOCRFromFile(new File("/Users/chz/Downloads/800.jpeg"),"chi_sim"); //指定要识别的图片文件
System.out.println("识别文本信息："+ocrText); //OCR识别结果：图像转文本
//testCapture();
} catch (Exception e) {
e.printStackTrace();
}
}
}
运行调试
一般会出现无法找到文件的错误,只要从tesseract的安装目录/usr/local/Cellar/tesseract下,把对应的文件COPY到对应的目录下即可解决.
错误信息:
