I want to start Opencv and Cuda Imaging library . So where can i get the resource to start with because i am not able to find any pre installed Opencv4tegra & Cuda support library in it .

JetPack itself is a front end to L4T install, so it is possible you have installed L4T version 23.2, 24.1 32-bit user space, or 24.1 64-bit user space. Some downloads for packages are listed on the individual L4T release page. To know which you have, “head -n 1 /etc/nv_tegra_release”. For various L4T release versions, see:

Thank a lot Sir , But it seems library isn’t installed while building OpenCv sample code show issue in Cmake

CMake Error at CMakeLists.txt:5 (find_package):
By not providing “FindOpenCV.cmake” in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by “OpenCV”, but
CMake did not find one.

and in home dir(~) there is no such dir call <JetPack_Install_Dir>/NVIDIA_CUDA-_Samples

[b]ubuntu@tegra-ubuntu:~$ head -n 1 /etc/nv_tegra_release

R24 (release), REVISION: 1.0, GCID: 7164062, BOARD: t210ref, EABI: aarch64, DATE: Tue May 17 23:37:30 UTC 2016[/b]

any clue Sir ?

The JetPack directory should be on your host machine, not on the Jetson. JetPack is a front end to the flash software, and also works as a front end to installing those extra packages (such as OpenCV). I cannot use JetPack (because I use Fedora host, and JetPack requires Ubuntu host), so I’m not sure where it would install OpenCV…but this would be an optional install from JetPack to either host or Jetson…you may want to run JetPack again (not to flash) and simply see what optional packages are installable…then be sure it is installed to Jetson rather than to host.
