OpenCV+OpenCV-Contrib源码编译_opencv_contrib编译

opencv_contrib编译

提示:文章写完后,目录可以自动生成,如何生成可参考右边的帮助文档


前言

提示:这里可以添加本文要记录的大概内容:

OpenCV是一款免费开源的计算机视觉算法库,在实际使用的时候,需要移植到不同的平台。在这记录下源码编译的过程。


提示:以下是本篇文章正文内容,下面案例可供参考

一、OpenCV是什么?

示例:pandas 是基于NumPy 的一种工具,该工具是为了解决数据分析任务而创建的。

二、OpenCV 源码编译

1.前期准备

1.1 源码下载

https://opencv.org/releases/OpenCV源码
下载指定的版本4.5.5

https://github.com/opencv/opencv_contrib/tags opencv_contrib4.5.5地址
在这里插入图片描述

1.2 cmake安装

1.3 vscode 安装

1.4 git 安装

1.5 mingw安装

2.源码编译

2.1 打开cmake

设置OpenCV 的路径和编译之后存放的路径

## 3. 问题汇总
### 3.1 Policy CMP0148 is not set: The FindPythonInterp and FindPythonLibs modules

```c
CMake Warning (dev) at cmake/OpenCVUtils.cmake:144 (find_package):
  Policy CMP0148 is not set: The FindPythonInterp and FindPythonLibs modules
  are removed.  Run "cmake --help-policy CMP0148" for policy details.  Use
  the cmake_policy command to set the policy and suppress this warning.

Call Stack (most recent call first):
  cmake/OpenCVDetectPython.cmake:64 (find_host_package)
  cmake/OpenCVDetectPython.cmake:286 (find_python)
  CMakeLists.txt:660 (include)
This warning is for project developers.  Use -Wno-dev to suppress it.

解决办法:在CMakeLists.txt 里面添加以下代码

```c
if(POLICY CMP0148)
  cmake_policy(SET CMP0148 OLD)  # CMake 3.13+: option() honors normal variables.
endif()

解决办法:路径一定要选到 opencv_contrib/modules 这里。

3.6 make 编译出现

在这里插入图片描述
说明源码被加密,需要解密。

4. 编译测试

4.1 配置OpenCV 库

打开vscode ,打开测试文件夹。

创建 .vscode文件夹,创建c_cpp_properties.json 、launch.json、task.json文件
