OpenCV和OpenCV-contrib配置中遇到的问题

一、环境

Microsoft Visual Studio 2022

opencv-4.5.5-vc14_vc15 .exe，以下简称“D:\OpenCV-4.5.5\opencv\build\include\opencv2”为OpenCV库文件夹。

opencv-contrib-4.5.5-zip。需要与opencv版本对应

cmake-3.24.0-rc1-windows-x86_64.msi。有博主说，4.5.5配cmake3.2.5及以上会报错，选择3.2.4成功配置环境。

https://cmake.org/files/

jdk-17_windows-x64_bin.msi

VTK-8.2.0.zip

以上资源下载链接

二、遇到的问题

2.1 配置环境遇到的问题

2.1.1CMake遇到的问题

2.1.1.1 JNI is not found

​ 重新下载安装jdk。安装时直接选择把路径添加到环境变量PATH中，就不用再配置环境变量了。

2.1.1.2 VTK is not found

Found JNI: C:/Program Files/Java/jdk-17/include  found components: AWT JVM 
VTK is not found. Please set -DVTK_DIR in CMake to VTK build directory, or to VTK install subdirectory with VTKConfig.cmake file
CMake Error at cmake/OpenCVModule.cmake:356 (_glob_locations):
  Syntax error in cmake code at

    D:/OpenCV-4.5.5/opencv/sources/cmake/OpenCVModule.cmake:356

  when parsing string

    D:\OpenCV-4.5.5\opencv_contrib-4.5.5\modules

  Invalid character escape '\O'.
Call Stack (most recent call first):
  cmake/OpenCVModule.cmake:385 (ocv_glob_modules)
  CMakeLists.txt:927 (ocv_register_modules)

​ 下载VTK，重新BUILD和INSTALL。我下载的版本未VTK-8.2.0。

​ 参照VTK下载并安装

2.1.1.3 “\o"转义字符出错。

​ 在CMake输入路径时，路径用的是"\“，需要改为使用”/"。

​ 如

2.1.1.4 无法启动程序 xxxxxxxxx 系统找不到指定的文件

​ 如下图

​ 该错误时因为没有配置“附加依赖项”。有可能你认为自己已经配置了“附加依赖项”，但是可能是你再opencv和opencv-contrib的编译过程中配置了“附加依赖项”，而将该配置 配置给了opencv项目或者opencv-contrib项目，而没有配置给你自己的项目，比如我这里没有配置“附加依赖项”给自己的“opencv_demo”项目。

2.1.1.5 无法打开输入文件“opencv——xxx.lib”。

原因时“附加依赖项”的路径不对，我最开始配置时，直接配置的时lib的名字，没有配置绝对路径。改为配置为绝对路径后，就可以正常运行了。

配置的依赖项目录，前面时自己刚才生成的newbuild目录下的库路径（每个人不一定相同）。

2.2 编写代码遇到的问题

2.2.1无法打开源文件：

• /face.hpp和face/facerec.hpp——>下载opencv_contrib，在里面找到face文件夹和face.hpp。然后将其拷贝到OpenCV库文件夹下。

2.2.2未定义符CvFont——>添加依赖

#include "opencv2/imgproc/imgproc_c.h"

2.2.3未定义符FaceRecognizer——>添加命名空间。

using namespace cv::face;

2.2.4未定义符createEigenFaceRecognizer（）

将该方法改为EigenFaceRecognizer::create()
