Start by installing OpenCV4.0.1 with Homebrew
$ brew install opencv
If Open3.4.5 is installed
brew install opencv@3
** If you need –with OpenGL ** you need to [download] to [email protected] and change the compilation configuration.
brew install ./[email protected]
Update if you find any updates;
Then configure it in the CLion project cmMakelists.txt as follows:
cmake_minimum_required(VERSION 3.9)
project(untitled1)
set(CMAKE_CXX_STANDARD 11)
#find_library(OpenCV)
find_package(OpenCV)
include_directories(${OpenCV_INCLUDE_DIRS})
set(CMAKE_CXX_STANDARD 11)
add_executable(untitled1 main.cpp)
target_link_libraries(untitled1 ${OpenCV_LIBS})
Then you can write main.cpp to verify that:
#include <iostream>
#include <opencv2/opencv.hpp>
using namespace std;
using namespace cv;
int main() {
Mat srcImage = imread("your_img_path.jpg");
if (!srcImage.data) {
std::cout << "Image not loaded";
return -1;
}
imshow("[img]", srcImage);
waitKey(0);
return 0;
}
You can display the photo, but if you can’t find the photo, change the path to the absolute path.
