Xavier NX - OpenCV 4.4
Xavier NX only works with JetPack 4.4 or later. And JetPack 4.4 is provided with OpenCV 4.1.1 installed. In most cases, there is no problem with using OpenCV 4.1.1. However, from OpenCV 4.2+, Super Resolution function is provided as C/C++ API. And from 4.3, it provides Python API. And finally, in 4.4, CUDA GPU acceleration is available. Therefore, it is recommended to use version 4.4 or higher to fully use the Super Resolution function provided by OpenCV. Therefore, to use OpenCV's SuperResolution, you need to delete the OpenCV 4.1.1 version of JetPack 4.4 and install 4.4 newly.
If you are not interested in OpenCV's SuperResolution feature, you do not necessarily need to upgrade to OpenCV 4.4.
Installing OpenCV 4.4
The description from now on can also be applied to Jetson Nano and Jetson TX2 using JetPack 4.4.
One thing to note is -D CUDA_ARCH_BIN="7.2", which specifies CUDA Architecture in the process of creating Makefile using cmake. Nano, TX2, and Xavier have different values. These values are described in JetsonNano-Useful tips before using Nano.
The following is a script file that can be easily installed.
每个板子对应的版本不一样，所以要根据板子修改参数。
