OpenCV Install on Apalis TK1

Technical Support

Hello,

I am trying to install Python3 and OpenCV 2 with Tegra support on my Apalis TK1 system running the L4T image that is provided via Easy Installer.

I have verified that Python3 is installed, and I have also installed version 6.5 of the Cuda Toolkit. However, when I run the cmake command for OpenCV, I do not see any reference to it detecting and validating Cuda support is enabled.

The cmake command I run is:

cmake -D CMAKE_BUILD_TYPE=RELEASE
-D CMAKE_INSTALL_PREFIX=/usr/local
-D WITH_CUDA=ON
-D ENABLE_FAST_MATH=1
-D CUDA_FAST_MATH=1
-D CUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-6.5
-D WITH_CUBLAS=1
-D INSTALL_PYTHON_EXAMPLES=ON
-D OPENCV_EXTRA_MODULES_PATH=…/…/opencv_contrib-3.1.0/modules
-D BUILD_EXAMPLES=ON …

The results I get back are:

HI @tk1hrsusr

Could you provide the version of the hardware and software of your module?

How did you install python 3 and OpenCV2? What is your application?

Hi @jaski.tx - thanks for the response.

I am working on the Apalis TK1 board (v1.2), using the Ixora carrierer board and running the L4T standard build that comes with the Easy Installer.

I also installed the Cuda toolkit version 6.5

I am using the following guide to install Open CV: Compiling OpenCV with CUDA support - PyImageSearch

Thanks for the Information. We will look into it and come back soon to you.

And why exactly would you not just use the OpenCV and Python versions that come pre-installed with JetPack?
