OpenCV Contrib on iMX6

ciaranbannon — Fri, 10 Nov 2017 14:55:22 GMT

I've built Linux for an i.MX6 SABRE as per the "i.MX Yocto Project User's Guide". It includes opencv but there is a "contrib" folder not present which I would like to use as it is in an old application which I am trying to cross-compile for the SABRE. Is there a way to add this to the Yocto build?

Hi,

The folder “contrib” depends of the OpenCV version. You could take a look at the following links for additional details:

https://docs.opencv.org/trunk/d7/d9f/tutorial_linux_install.html

https://community.nxp.com/docs/DOC-331941

Hope this will be useful for you.
Best regards!

Thanks for that info Carlos.

The functions from contrib are located in different libraries in the later versions of OpenCV, so the solution was to amend the include paths to where these functions are now located.
