Releases - OpenCV现成的dll和so传不上来，可自行到官网下载相应版本的opencv库这里以4.0.1为例Releases - OpenCV

Linux

1.将opencv-4.0.1目录拷贝到服务器根目录 /  (可放到任何目录，后续配置做相应更改即可，这里以根目录为例)
2. 打开系统配置目录  cd /etc/ld.so.conf.d/
3.创建配置文件  vi opencv-4.0.1.conf 
4.写入库路径   
    /opencv-4.0.1/install/lib64   
   :wq 保存关闭
5.执行 ldconfig 命令
6.将 /opencv-4.0.1/install/share/java/opencv4/libopencv_java401.so 拷贝到 /usr/lib下
7.在java代码main函数中增加以下代码

import org.opencv.core.Core;

try {
       System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
    } catch (UnsatisfiedLinkError ignore) {
    }

8.在项目pom中增加依赖

<dependency>
   <groupId>org.bytedeco.javacpp-presets</groupId>
   <artifactId>opencv</artifactId>
   <version>4.0.1-1.4.4</version>
</dependency>
<dependency>
   <groupId>org.bytedeco</groupId>
   <artifactId>opencv-platform</artifactId>
   <version>4.3.0-1.5.3</version>
</dependency>

windows

1.将dll目录中所有dll拷贝到 C:\Windows\System32下
2. 在java代码main函数中增加以下代码，springboot项目是在@SpringBootApplication 下的main

import org.opencv.core.Core;

try {
       System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
    } catch (UnsatisfiedLinkError ignore) {
    }

3.在项目pom中增加依赖

   <groupId>org.bytedeco.javacpp-presets</groupId>
   <artifactId>opencv</artifactId>
   <version>4.0.1-1.4.4</version>
