Installing the OpenCV for development

The same way as in the GStreamer installation, you can install OpenCV in this board, you just need to go to the local.conf file at:

cd $HOME/<your image folder>/<your build directory>/conf/
cat local.conf

In this file, just add the following lines:

# -- OpenCV stuff --
IMAGE_INSTALL_append += "opencv"

CORE_IMAGE_EXTRA_INSTALL += "libopencv-core-dev libopencv-highgui-dev libopencv-imgproc-dev libopencv-objdetect-dev libopencv-ml-dev opencv-apps opencv-dev"

Building the image with the changes in local.conf

cd $HOME/<your image folder>

source setup-environment <your build directory>

bitbake imx-image-core

Testing the OpenCV installation
