About version of opencv on sdcard image(NANO)

Hello,

  1. I am trying to make a simple vision library using opencv library.

  2. I want to know what opencv version is installed in the developer kit sdcard image and how to check it.

  3. And what is the recommended method when using opencv in jetson?

  4. What is the relationship between visionworks and opencv?

Thank you.

Not sure what’s the use case you want to develop, you may need to search the forum to find more references.
