BB AI and OpenCV 3.3+

vlasov01 over 5 years ago

I know BB AI comes with OpenCV 3.2.

I'd like to use BB AI with OpenCV Deep Neural Networks (dnn module) on my project. It comes with OpenCV 3.3 or later.

I'm wondering if anyone was able to get OpenCV 3.3 or later for BB AI?

If yes, are you still benefiting from BB AI hardware accelerators?

I was able to build OpenCV 4.1.2 on BB AI.
(cv) debian@beaglebone:~$ python -c "import cv2; print(cv2.__version__)" 4.1.2
I'm not sure yet if it is using accelerators as I'm getting "TIOCL FATAL: Failed to open file /dev/mem" error when I'm calling dnn module from python.

Use su before python command.

Arguments given to su will be interpreted as usernames, you're thinking of sudo

sudo python -c "import cv2; print(cv2.__version__)"
