# Install minimal prerequisites (Ubuntu 18.04 as reference)
sudo apt update sudo apt install -y cmake g wget unzip
# Download and unpack sources
wget -O opencv.zip https://github.com/opencv/opencv/archive/4.x.zip
wget -O opencv_contrib.zip https://github.com/opencv/opencv_contrib/archive/4.x.zip
unzip opencv.zip
unzip opencv_contrib.zip
# Create build directory and switch into it
mkdir -p build cd build
# Configure
cmake -DOPENCV_EXTRA_MODULES_PATH../opencv_contrib-3.4/modules ../opencv-3.4.13
# Build
cmake --build . -j4
这里注意如果wget无法下载要自己手动下载3.4.13的OpenCV及contrib安装包 https://github.com/opencv/opencv/archive/3.4.13.zip https://github.com/opencv/opencv_contrib/archive/3.4.zip
我将上述的build文件放在/home/ProfSnail/software/opencv3.4.13/build下面在使用CMakeLists.txt的时候要指定路径。比如
project(PieceSeg)
cmake_minimum_required(VERSION 3.0)
set(CMAKE_CXX_STANDARD 14)
set(CMAKE_BUILD_TYPE Release)set(OpenCV_DIR /home/ProfSnail/software/opencv3.4.13/build)
find_package(OpenCV REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})add_executable(calibration calibration.cpp)
target_link_libraries(calibration ${OpenCV_LIBS} cnpy)
