CUDA Accelerated GStreamer Camera Undistort - Getting Started - Building the Undistort

Dependencies

The cuda undistort library has the following dependencies:

Meson

The image distortion correction library makes use of the Meson build system. To build correctly this library you need to use the latest version of Meson:

First, make sure python dependencies and ninja are installed

sudo apt-get install python3 python3-pip python3-setuptools \
                       python3-wheel ninja-build

Then use pip3 install Meson directly from its repository.

sudo -H pip3 install git+https://github.com/mesonbuild/meson.git

JSON-GLib

sudo apt-get install libjson-glib-dev

GstCuda

To install GstCuda see the GstCUDA - Building and Installation Guide.

OpenCV

If you pretend to use the undistort with the Cuda-Stitcher element, follow the instructions for Compiling OpenCV for Image Stitching, since the stitcher requires a specific version of RidgeRun's OpenCV Fork

On the other hand, if you are using the undistort as a standalone element, just install OpenCV with the CUDA module enabled from here.

Building the project

Once you have met the requirements, execute the following commands:

meson build --prefix /usr
ninja -C build
sudo ninja -C build install
