我是Android开发的新手。我正在尝试使用我发现的代码（感谢@micfra）应该做我想要的，这是：
我设置了我的工作环境，安装了OpenCV库，NDK，SDK，ADT。我创建了一个简单的Android应用程序，将图像放入res文件夹并编辑MainActivity.java文件，如下所示：
package com.example.match;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import org.opencv.core.Core;
import org.opencv.core.Core.MinMaxLocResult;
import org.opencv.core.CvType;
import org.opencv.core.Mat;
import org.opencv.core.Point;
import org.opencv.core.Scalar;
import org.opencv.highgui.Highgui;
import org.opencv.imgproc.Imgproc;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
run("bmp1.bmp", "bmp2.bmp", "bmp3.bmp", Imgproc.TM_CCOEFF);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void run(String inFile, String templateFile, String outFile, int match_method) {
System.out.println("\nRunning Template Matching");
Mat img = Highgui.imread(inFile);
Mat templ = Highgui.imread(templateFile);
// / Create the result matrix
int result_cols = img.cols() - templ.cols() + 1;
int result_rows = img.rows() - templ.rows() + 1;
Mat result = new Mat(result_rows, result_cols, CvType.CV_32FC1);
// / Do the Matching and Normalize
Imgproc.matchTemplate(img, templ, result, match_method);
Core.normalize(result, result, 0, 1, Core.NORM_MINMAX, -1, new Mat());
// / Localizing the best match with minMaxLoc
MinMaxLocResult mmr = Core.minMaxLoc(result);
Point matchLoc;
if (match_method == Imgproc.TM_SQDIFF || match_method == Imgproc.TM_SQDIFF_NORMED) {
matchLoc = mmr.minLoc;
} else {
matchLoc = mmr.maxLoc;
}
// / Show me what you got
Core.rectangle(img, matchLoc, new Point(matchLoc.x + templ.cols(),
matchLoc.y + templ.rows()), new Scalar(0, 255, 0));
// Save the visualized detection.
System.out.println("Writing "+ outFile);
Highgui.imwrite(outFile, img);
}
}
当我尝试在手机上执行应用程序时，它只执行几秒钟，然后以“意外停止”终止。我知道，它没有提供很多关于错误的信息，但代码编译没有错误，我不知道从哪里开始。正如我所提到的，我对Android和Java完全陌生，任何帮助都会受到赞赏。

在run方法中将.bmp文件作为参数发送，因为它的参数会导致问题，而不是这样做你可以实现与
相同的事情将run方法更改为：
public void run(int inFile, int templateFile, String outFile, int match_method)
并替换以下2行
Mat img = Highgui.imread(inFile);
Mat templ = Highgui.imread(templateFile);
并使用此
Mat img = new Mat();
Mat templ= new Mat();
try {
img= Utils.loadResource(this, inFile);
templ= Utils.loadResource(this, templateFile);
} catch (IOException e) {
e.printStackTrace();
}
现在，将所有bmp图像放在drawable文件夹中，并使调用以
运行 run(R.drawable.bmp1, R.drawable.bmp2, R.drawable.bmp3, Imgproc.TM_CCOEFF);
这对我来说很好，我相信它会对你有用
