About

This repository contains the sources of the examples from screencasts about OpenCV programming on NVidia Jetson platform.

Prerequisites

  • All the examples are built with the help of CMake build system. To install it, run the following command in the terminal:
  $ sudo apt-get install cmake
  • The only dependency of the examples is the OpenCV4Tegra library. It should be installed on the platform as part of the JetPack package. If, for some reason, you don't have it installed on the system, you can try the following command:
  $ sudo apt-get install libopencv4tegra-dev

Building

Each example is self-contained and is located in a separate folder. All of them can be built using the same procedure:

  • Go to the directory of the sample
$ cd ~/0-cv-hello
  • Create build directory and go to it
$ mkdir build
$ cd build
  • Run cmake to generate a Makefile
$ cmake ..
  • Run make to build the executable
$ make
  • Go one level up (so that the application can locate the media files) and run the executable
$ cd ..
$ ./build/cv_hello

Notes

  • Examples 11-cv-perf, 12-cv-threads, 13-cv-neon, 14-cv-gpu use C++11 features
  • Examples 12-cv-threads and 13-cv-neon use OpenMP.
  • Example 13-cv-neon uses NEON compiler intrinsics.
