I’m using the Jetson Nano with Jetpack 4.2.1, which includes OpenCV 3.1.1. I’m thinking of upgrading to the latest release of OpenCV using the script mentioned here: https://devtalk.nvidia.com/default/topic/1051133/jetson-nano/opencv-build-script/post/5334837/#5334837. However, I’ve noticed that OpenCV code contains a HAVE_TEGRA_OPTIMIZATION flag and an internet search has led me to the following two links (neither about the Jetson Nano) which suggest there is a Tegra optimised version of OpenCV:
My questions are:
- Is the version of OpenCV in Jetpack 4.2.1 optimized for Tegra?
- If so, is it possible to upgrade to a newer version of OpenCV without losing this optimization?
- If I choose not to upgrade, but want to recompile OpenCV in order to build it for CUDA, is it possible to do that without losing the optimization?
