1、OpenCV Windows10 环境搭建

OpenCV windows 版本下载地址：[https://sourceforge.net/projects/opencvlibrary/files/opencv-win/][https_sourceforge.net_projects_opencvlibrary_files_opencv-win]

点击运行：opencv-3.4.3-vc14\_vc15.exe，双击运行安装一个目录后找到C:\\openCV\\opencv\\build\\java`,如下图：`

`2、配置OpenCV, Windows10系统全局环境变量（PATH），如下截图：`

3、Eclipse 搭建Maven 项目基于OpenCV 的开发环境。

第一步：打开OpenCV 安装目录（C:\\openCV\\opencv\\build），将Java目录下的opencv-343.jar，上传至本地Maven 仓库，执行代码如下：

mvn install:install-file -Dfile=C:\\openCV\\opencv\\build\\java\\opencv-343.jar -DgroupId=com.opencv -DartifactId=opencv -Dversion=1.0.0 -Dpackaging=jar

第二步：创建Maven项目，依赖本地仓库的OpenCV.jar 文件

重点注意：OpenCV.jar 实现相关功能源码是基于c 或 c++ 语言实现，OpenCV只是进行简单封装，这里就涉及jar文件依赖.dll文件(Windows环境)。操作如下：将C:\\openCV\\opencv\\build\\java\\x64\\opencv\_java343.dll 文件 绑定给opencv.jar文件。截图如下：

第三步：功能实现-输出图片

package com.zzg.opencv;
    
    import java.io.File;
    
    import org.opencv.core.Core;
    import org.opencv.core.Mat;
    import org.opencv.highgui.HighGui;
    import org.opencv.imgcodecs.Imgcodecs;
    
    public class Bootstartp {
    	static {
            System.loadLibrary(Core.NATIVE_LIBRARY_NAME);  //加载动态链接库
        }
    	public static void main(String[] args) {
    		// TODO Auto-generated method stub
    		  String fileName = "C:\\openCV-image\\spring-security.png"; //设置图片的路径
    	        if (!new File(fileName).exists()){
    	            System.out.println("文件不存在");
    	        }else{
    
    	            Mat srcImg = Imgcodecs.imread(fileName);  //opencv读取
    	            if (srcImg.empty()){
    	                System.out.println("加载图片失败！");
    	            }else{
    	                HighGui.imshow("image",srcImg); //显示
    	                HighGui.waitKey(0);
    	            }
    	        }
    
    	}
    
    }
