some problem about opencv

[zhendebufapyq]

Whether using EuRoC Example or D455 camera, this error will occur. I cannot view the opencv version using the pkg config -- modversion opencv command, but jtop can still see it (I use it on orin nx)

You may need to install opencv version 3.4 @dahexiangdong6 @zhendebufapyq
