主要参考博客：Ubuntu16.04下安装OpenCV3.2.0
主要问题：
libjasper-dev 找不到：https://blog.csdn.net/weixin_41053564/article/details/81254410
cmake报错参考博客：https://blog.csdn.net/u014613745/article/details/78310916
make时ffmpeg模块报错：https://stackoverflow.com/questions/46884682/error-in-building-opencv-with-ffmpeg
如果要用cuda则使用下面的cmake参数:
cmake -D CMAKE_INSTALL_PREFIX=/usr/local -D CUDA_GENERATION=Kepler -D WITH_LAPACK=OFF -D WITH_BLAS=OFF ..
如果用扩展模块 ：
cmake -D CMAKE_INSTALL_PREFIX=/usr/local -D CUDA_GENERATION=Kepler -D WITH_LAPACK=OFF -D WITH_BLAS=OFF -D CMAKE_BUILD_TYPE=Release -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules -D WITH_LIBV4L=ON -D WITH_GTK=ON -D WITH_OPENGL=ON ..
参数说明:
| 参数 | 意义 |
|---|---|
| WITH_LIBV4L | 是与usb摄像头有关的参数 |
| WITH_CUDA | 看看你有没有装cuda |
如果有make时有报以下错误：
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
CUDA_nppi_LIBRARY (ADVANCED)
linked by target "opencv_cudev" in directory D:/Cproject/opencv/opencv/sources/modules/cudev
linked by target "opencv_cudev" in directory D:/Cproject/opencv/opencv/sources/modules/cudev
linked by target "opencv_test_cudev" in directory D:/Cproject/opencv/opencv/sources/modules/cudev/test
.......
