tess4j基本使用方法

1.引入jar包

<dependency>
    <groupId>net.sourceforge.tess4j</groupId>
    <artifactId>tess4j</artifactId>
    <version>4.3.1</version>
</dependency>

2.编写java类测试

import net.sourceforge.tess4j.ITesseract;
import net.sourceforge.tess4j.Tesseract;
import net.sourceforge.tess4j.TesseractException;

import java.io.File;

public class Demo {
    public static void main(String[] args) {
        ITesseract instance = new Tesseract();
        instance.setDatapath("D:\\Users\\Tess4J\\tessdata");
        instance.setLanguage("chi_sim");

        File file = new File("D:\\work\\timgs.png");
        try {
            String result = instance.doOCR(file);
            System.out.printf(result);
        } catch (TesseractException e) {
            e.printStackTrace();
        }
    }
}

3.执行结果


4.总结：执行结果基本上和图片类似，为了更加精准，可以训练。
