由于mac上 brew install opencv是不带viz模块的，所以需要源码编译

1、下载opencv和vtk源码

1

3
opencv:https://opencv.org/releases.html

vtk:https://www.vtk.org/download/

当然也可以通过git clone

git clone  https://gitlab.kitware.com/vtk/vtk.git VTK

cd VTK

git checkout vX.X.X

git clone https://github.com/opencv/opencv.git 

cd opencv

git checkout X.X.X

git clone https://github.com/opencv/opencv_contrib.git

cd opencv_contrib 

git checkout X.X.X

2、编译

需要安装一个CMAKE

(1) 编译vtk

1、source code配置为vtk目录

2、binaries配置为vtk/build目录

3、configure的时候要选择xcode

4、配置 VTK_RENDERING_BACKEND为OpenGL

5、再configure再generate

6、然后打开xcode 需要修改/usr/local目录，所以需要root权限

7、得这么打开sudo /Applications/Xcode.app/Contents/MacOS/Xcode

8、然后在xocde里打开vtk/build，先跑ALL BUILD再跑install

(2) 编译opencv

1、source code配置为opencv目录

2、binaries配置为opencv/build目录

3、配置OPENCV_EXTRA_MOULES_PATH**设置为*/opencv_contrib/modules

4、配置VTK_DIR**设置为vtk/build

5、然后在xocde里打开opencv/build，先跑ALL BUILD再跑install

3、加环境变量

1
2
3
4
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig

这里要特别注意了，因为默认opencv.pc是没有加入viz模块的所以在/usr/local/lib/pkgconfig/opencv.pc里的
Libs:后面加上-lopencv_viz

4、运行

1、如果是在命令行运行，MakeFile中加入

1
CFLAGS += `pkg-config --cflags --libs opencv`

2、如果是在xcode里运行，Build Settings-Other Linker Flags加入
opencv.pc里Libs后的内容，这是在我的xcode里加的

1
-L/usr/local/lib -lopencv_viz -lopencv_stitching -lopencv_superres -lopencv_videostab -lopencv_aruco -lopencv_bgsegm -lopencv_bioinspired -lopencv_ccalib -lopencv_dnn_objdetect -lopencv_dpm -lopencv_face -lopencv_photo -lopencv_fuzzy -lopencv_hfs -lopencv_img_hash -lopencv_line_descriptor -lopencv_optflow -lopencv_reg -lopencv_rgbd -lopencv_saliency -lopencv_stereo -lopencv_structured_light -lopencv_phase_unwrapping -lopencv_surface_matching -lopencv_tracking -lopencv_datasets -lopencv_dnn -lopencv_plot -lopencv_xfeatures2d -lopencv_shape -lopencv_video -lopencv_ml -lopencv_ximgproc -lopencv_calib3d -lopencv_features2d -lopencv_highgui -lopencv_videoio -lopencv_flann -lopencv_xobjdetect -lopencv_imgcodecs -lopencv_objdetect -lopencv_xphoto -lopencv_imgproc -lopencv_core

PS:centos服务器上按这个步骤也可以，只是编译的目录是在/usr/lib64下
如果运行带界面的demo会报错 DISPLAY(ABOUT)

参考:【教程】使用CMake编译含有viz.hpp的OpenCV310+OpenCV contrib
