OpenCV最简JAVA版范例

Posted 2021-09-06 柳鲲鹏

　　同事老是抱怨跑不起来，于是吾抄了个范例：

package taishan;

import java.io.File;

import org.opencv.core.CvType;
import org.opencv.core.Mat;

@SuppressWarnings("serial")
public class OpenCVTest
{
	public static void main(String[] args)
	{
		System.out.println(System.getenv("java.library.path"));
        //System.loadLibrary("opencv_java422");
		String fileName = "/home/tsit/eclipse-workspace/FontTest/lib/libopencv_java420.so";
		System.out.println(new File(fileName).exists());
        //如果是多个分包的形式，要各自加载
		System.load(fileName);
		
        Mat m  = Mat.eye(3, 3, CvType.CV_8UC1);  
        System.out.println("m = " + m.dump());  
    }
}

　　关键的一句就是要正确找到so包。
