After my JETSON NANO burned the system, OPENCV4.1.1 already exists, but now a lot of code is still using OPENCV3, so I need to manually install a
record of the errors and solutions during the installation process
Opencv3.4.5 and opencv_contrib-3.4.5 Share with ippicv
Link: https://pan.baidu.com/s/1-gtr7cgkZ1tlDdqw4Eu-Hg
extraction code: mcz0
decompress opencv_contrib-3.4.5 in the opencv3.4.5 directory
Dependency reference this

OPENCV compilation with CUDA
cd opencv-3.4.5

cd build

Make reports that there is no opencv2 / xfeatures2d / cuda.hpp file.
Search and find it in /opencv-3.4.5/opencv_contrib-3.4.5/modules/xfeatures2d/include/opencv2/xfeatures2d. Change
the address.

If you want to use OPENCV3 instead of the default 4, you need to add FIND_PACKAGE (OpenCV REQUIRED) in CMakeLists.txt, add a sentence before set (OpenCV_DIR "/ usr / local / opencv3 / share / OpenCV"), refer to this
CMAKE_MINIMUM_REQUIRED( VERSION 2.8)
PROJECT(useOpenCV)
set(OpenCV_DIR "/usr/local/opencv3/share/OpenCV")
FIND_PACKAGE(OpenCV REQUIRED)
INCLUDE_DIRECTORIES(${OpenCV_INCLUDE_DIRS})
add_executable(useOpenCV useOpenCV.cpp)
TARGET_LINK_LIBRARIES(useOpenCV ${OpenCV_LIBRARIES})
