Hello Sbo05050,

Thank you for your interest in the Intel RealSense products.

Can you please tell me which version of OpenCV are you using?

Regards,

Thank you for your message.

Can you also please tell me which librealsense version you are using?

July 18, 2019 07:35

I am currently using librealsense 2.24 version.

Do other RealSense samples that use OpenCV compile and function correctly?

What version of Linux and kernel are you using?

If rs-dnn is the only sample that does not work, then you should completely uninstall OpenCV and reinstall it, then try again.
