Hi, I’ve recently started using a Jetson AGX Xavier Dev Kit, I notice that the SDK Manager on the Host PC installs OpenCV on the Xavier. But when I run the command: print(cv2.getBuildInformtion()) It confirms that it is the latest build of OpenCV 4.1.1 but does not confirm whether it is nativel…

I don’t know about licensing issues but I know the issue is in part but that OpenCV’s cuda module does have some issues relating to the performance and stability. If you ever run the test suite when building OpenCV, you’ll see that there are quite a few things that are broken. It’s a lot to ask Nvid…

Hi mff745: Our official OpenCV package(installed from sdkmanager ) does support CUDA. release in each JetPack does, you should try to rebuild the opencv + cuda from source. try the script from JEP/script at master · AastaNV/JEP · GitHub to install

Thanks for your reply, I have now installed the latest openCV build with CUDA support on my Xavier.

I have resolved this issue. You do have to purge the OpenCV install that the SDK Manager installs as it is installs a version without CUDA enabled (which seems counter intuitive). You can do this via: sudo apt-get -y purge libopencv-dev libopencv-python libopencv-samples libopencv* sudo apt-get -…

I removed all versions of opencv on my system and than reinstalled opencv 4.1.1 using the SDK manager. I can confirm the header files for CUDA support in opencv don’t get installed. I also looked at which files are installed by SDK manager in the opencv dev package using dpkg -L libopencv-dev - open…

What steps are you doing for installation? dpkg or cmake? sudo apt purge libopencv-dev libopencv-python libopencv-samples libopencv* sudo apt update git clone GitHub - opencv/opencv: Open Source Computer Vision Library cd opencv git checkout $cvVersion cd … git clone GitHub - opencv/opencv_c…

Thanks mff745 - I managed to build and install OpenCV now with CUDA support

[image] mff745: Begin compiling Hi, I have flowed these steps and I manage up to the “Begin compiling section” , where I get the next error: cmake -D CMAKE_BUILD_TYPE=RELEASE CMake Error: The source directory “/home/marko/opencv/build/CMAKE_BUILD_TYPE=RELEASE” does not exist. Any advice o…

Here is a build script with cuda and all the fun non-free trimmings enabled. Here are pre-built docker images for JetPack 4.3 and 4.4 of the latest OpenCV. The Dockerfile and build scripts are here if you wish to build it yourself. Note: I build and provide these but I recommend you use Nvidia spe…

For some reason the code block removes the backslash character a the end of each line. All of the lines with a “-D” should also end with a \ as all -D should be passed with the cmake command. You can also type it all out on one line too: cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX = …

Similar situation here I have installed JetPack 4.4 DP on Xavier AGX using the SDK manager. I’m missing cudawarping.hpp - which I assume should be found in /usr/include/opencv4/opencv2. Any idea why this is not install ? As you pointed out OpenCV comes with CUDA support - should than cudawarping.hpp not have been installed? Do I’m missing something?
