Script to build OpenCV 4.9.0 with CUDA and CUDNN support on the NVIDIA Jetson AGX Orin
Note: The script does not check to see which version of L4T is running before building, understand the script may only work with the stated versions.
usage: ./buildOpenCV.sh [[-s sourcedir ] | [-h]]
-v | --version Change the version of OpenCV to install. (default: 4.9.0)
-s | --sourcedir Directory to place the opencv sources (default: /tmp/build_opencv)
-i | --installdir Directory to install opencv libraries (default: /usr/local)
-t | --test Download examples and test the OpenCV after building.
-p | --package Package OpenCV as .deb file to install in other JETSONs.
-r | --remove Ask to remove previous installations from OpenCV alongside all files related.
-h | --help Print help
OpenCV will be installed in the /usr/local directory as default, all files will be copied to the following locations:
/usr/bin- executable files/usr/lib/aarch64-linux-gnu- libraries (.so)/usr/lib/aarch64-linux-gnu/cmake/opencv4- cmake package/usr/include/opencv4- headers/usr/share/opencv4- other files (e.g. trained cascades in XML format)
OpenCV is a very rich environment, with many different options available. Check the script to make sure that the options you need are included/excluded. By default, the buildOpenCV.sh script selects these major options:
- CUDA ON
- CUDNN ON
- GStreamer
- V4L - (Video for Linux)
- QT - (No gtk support built in)
- Python 3 bindings
By default, the build will create a OpenCV package. The package file will be found in:
opencv/build/_CPACK_Packages/Linux/STGZ/OpenCV-4.9.0-<commit>-aarch64.sh
The advantage of packaging is that you can use the resulting package file to install this OpenCV build on other machines without having to rebuild. Whether the OpenCV package is built or not is controlled by the CMake directive CPACK_BINARY_DEB in the script.
Building for:
- Jetson AGX Orin
- JetPack 5.1.2 (CUDA 8.7, CUDNN 8.9)
- OpenCV 4.9.0
- Packaging Option
