Prerequisite #
Install cmake and opencv.
Linux #
sudo apt install cmake build-essential
sudo apt install libopencv-devWindows #
Install cmake, OpenCV and Visual Studio (we use VS2019).
Installation Guide on Windows #
Create two files, example.cpp and CMakeLists.txt with following content.
# CMakeLists.txt
cmake_minimum_required(VERSION 3.3)
project( example CXX )
if(MSVC)
include_directories("C:/Program Files/OpenNI2/Include")
link_directories("C:/Program Files/OpenNI2/Lib")
endif()
add_executable( ${PROJECT_NAME} project.cpp )
find_package(OpenCV)
target_link_libraries(${PROJECT_NAME} OpenNI2)
target_link_libraries(${PROJECT_NAME} ${OpenCV_LIBS})// project_setup.cpp
#include <openni2/OpenNI.h>
#include <opencv2/core/core.hpp>
int main()
{
auto version = new openni::Version();
printf("OpenNI Version:%d.%d.%d.%d\n", version->build, version->major, version->minor, version->maintenance);
printf("OpenCV Version:%s\n", CV_VERSION);
return 0;
}Build #
Linux #
Create a build folder next to CMakeLists.txt. Change directory to build folder. Use cmake to generate build files. Then use make to build.Copy
mkdir build
cd build
cmake ..
makeWindows #
1. Open Visual Studio and create a new project
2. Create a new cmake project
3. Modify CMakeLists.txt and project_setup.cpp
Expect output #
OpenNI Version:0.0.0.0
OpenCV Version:4.2.0.4.2.0
