Cross Compile OpenCV C++ for iMX6ULEVK ?

toanjunifer — Fri, 07 Feb 2020 08:31:02 GMT

Hi everyone,

My name is Toan. I'm using iMX6UL-EVK. And I'm trying to install OpenCV C++ on my iMX6UL-EVK. I tried install with source code but It takes about 3 days. It's really a long time. Now I found and tried some solution with cross-compile but not working. I tried with "sshfs" and "cmake-gui".

What should I do now ? Or how to cross-compile <OpenCV C++ program>.cpp to executable file for iMX6UL ?

Thank you very much,

Toan

as I known, the latest bsp version includes opcv already, you don't need to build it by yourself

Hi joanxie‌,

Nice to meet you. That OpenCV was bound with Python not C++. I checked it.

Some resources said that performance of OpenCV-C++ is greater than OpenCV-Python.

The write video command in OpenCV-Python on my iMX6ULEVK take 0.1 second to finish, it's so long. And I trying to optimize my program.

Best regards,

Toan

Yes... but there are no header files even though all the .so files are present in /usr/lib...

So how to include opencv2/opencv.hpp in a c++ program ?
