How to Build OpenCV on Jetson Modules?

ENVIRONMENT

 Hardware: Jetson AGX Xavier

 OS: Jetpack 4.6


In this blog post, you will learn how to build OpenCV on Jetson modules. If you have not installed OpenCV yet, you can by following the steps in this blog post.


https://www.forecr.io/blogs/installation/how-to-install-opencv-with-cuda-support

First, download OpenCV repository with extra modules from GitHub using the following command and extract them.


curl -L https://github.com/opencv/opencv/archive/4.4.0.zip -o opencv-4.4.0.zip
curl -L https://github.com/opencv/opencv_contrib/archive/4.4.0.zip -o opencv_contrib-4.4.0.zip
unzip opencv-4.4.0.zip
unzip opencv_contrib-4.4.0.zip

Go to the downloaded directory and create a build folder.


cd opencv-4.4.0/
mkdir build && cd build


Run the cmake and make commands to compile the OpenCV scripts. This could take a while.


cmake -D WITH_CUDA=ON -D CUDA_ARCH_BIN="5.3,6.2,7.2" -D CUDA_ARCH_PTX="" -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-4.4.0/modules -D BUILD_TESTS=OFF -D BUILD_PERF_TESTS=OFF -D BUILD_EXAMPLES=OFF -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_opencv_sfm=OFF ..
make -j6

Then, run the following command to build OpenCV. 


sudo checkinstall -D make install 


Change the first four values as the following:

#0 - Maintainer: [ admin@opencv.org ]

#1 - Summary: [ Open Computer Vision Library (with Cuda 10.2) ]

#2 - Name: [ libopencv-4.4.0 ]

#3 - Version: [ 4.4.0 ]



After entering the values, installation will start. You can press Enter to all the questions while installing.

  


At the end, give permissions to the Debian package and change its name if you wish. Here, 4.4.0-1 is the Name of the Debian package that is changed at the previous step. You should use what you have written before.


sudo chmod 666 libopencv-4.4.0_4.4.0-1_arm64.deb
mv libopencv-4.4.0_4.4.0-1_arm64.deb libopencv-4.4.0_arm64_jetpack_4.6_xavier.deb


You can also see the packages installed using the following command.


dpkg --contents libopencv-4.4.0_arm64_jetpack_4.6_xavier.deb
