我要求它识别图像中存在的字符，我们要求它读取内容并将内容存储在变量中

Question

我已经写了这段代码：

import java.awt.Image;
import java.awt.image.RenderedImage;
import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;
import javax.imageio.ImageIO;
import org.apache.commons.io.FileUtils;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.DesiredCapabilities;
import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.remote.MobileCapabilityType; 

// class and method declaration omitted

File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
//store screenshot at a specidfied location
File targetFile=new File("C:\\Users\\Srujan\\eclipse-workspace\\Batch98Appium\\images\\kiran.png");
FileUtils.copyFile(scrFile,targetFile );
System.out.println(targetFile.toString());

// URL url1 = new URL(targetFile.toString());  
Image image = ImageIO.read(targetFile);         

// we are asking it to recognize the characers present in the image and we are asking to it to read the contnet and to store the content in a variable
String s = new OCR().recognizeCharacters((RenderedImage) image);  

//below cmd is simply printing the information
System.out.println("Text From Image : \n"+ s);  

if (s.contains("Monitored switch is on")) {
    System.out.println("toastr verified successfully");
} else {
    System.out.println("toastr not verified successfully");
}

我添加了 jars 作为 Maven 依赖项：

Java OCR API 15.3.0.1

java-client 6.1.0

出现如下编译错误：

String s = new OCR().recognizeCharacters((RenderedImage) image);

OCR().Recog...OCR 无法解析为类型。

您没有包含 Ocr 类的导入（顺便注意小写字母）。在文件顶部附近添加：

 import com.asprise.ocr.Ocr;

并将类名更正为Ocr。
