+# MxVision快速入门——开发opencv的均一化插件
+
+## 1 介绍
+
+### 1.1 简介
+
+opencv的均一化插件开发样例基于c++代码，生成SDK插件，以用于自定义插件后处理开发。该插件用于对输入的图像或帧进行均一化，适用于输入输出均为YUV的场景。
+
+### 1.2 支持的产品
+
+本项目支持昇腾Atlas 300I pro、 Atlas 300V pro
+
+### 1.3 支持的版本
+
+| MxVision版本 | CANN版本  | Driver/Firmware版本 |
+|------------|---------|-------------------|
+| 6.0.RC3   | 8.0.RC3   |  24.1.RC3  |
+
+
+## 2 设置环境变量
+
+```
+# MindX SDK环境变量:
+.${SDK-path}/set_env.sh
+
+# CANN环境变量:
+.${ascend-toolkit-path}/set_env.sh
+
+# 环境变量介绍
+SDK-path:SDK mxVision安装路径
+ascend-toolkit-path:CANN安装路径
+```
+
+## 3 编译与运行
+
+**步骤1：** 在项目根目录下创建build文件夹，使用cmake命令进行编译，生成插件*.so文件：
+
+```
+# 创建build目录
+mkdir build
+cd build
+# cmake编译
+cmake ..
+make
+```
+**步骤2：** 查看结果：执行成功后会在`mindxsdk-referenceapps/lib/plugins/`下生成插件*.so文件。
