Opencv 安装配置-windows

opencv 3.X以后对一些不稳定的模块提取了出来。比如收费的算法等，windows下编译是一个很费事的事情。我费老大劲编译好了一个带 contrib 模块的opencv。

• 文件下载完成后解压在一个无空格和中文的目录。eg:Z:\ProgramFiles\myopencv343\
• 添加环境变量。eg:Z:\ProgramFiles\myopencv343\x64\vc15\bin
• 复制dll到%JAVA_HOME%\jre\bin\目录下。eg:Z:\ProgramFiles\myopencv343\java\opencv_java343.dll ==> Z:\ProgramFiles\Java\jdk1.8.0_192\jre\bin
• 新建基于maven的java项目，pom如下

• 新建Class 测试

package cn.edu.zua.javacv;

import org.opencv.core.Core;
import org.opencv.core.Mat;
import org.opencv.highgui.HighGui;
import org.opencv.imgcodecs.Imgcodecs;

/**
 * Hello world!
 *
 */
public class App {
    public static void main( String[] args ) {
        System.loadLibrary(Core.NATIVE_LIBRARY_NAME);

        Mat horse = Imgcodecs.imread("/tmp/shine0.jpg");
        HighGui.imshow("result", horse);
        HighGui.waitKey();
        System.exit(0);

    }
}

效果如下
