我目前正在尝试让OpenCV与Linux（Ubuntu 16.04），cmake 3.5.1上的OpenCV额外模块（尤其是跟踪模块）一起使用 我从https://opencv.org/releases.html下载了3.4.5版的OpenCV，并从https://github.com/opencv/opencv_contrib/releases/tag/3.4.5下载了OpenCV contrib 3.4.5。 然后，我遵循了Linux的OpenCV官方文档中的教程：https://docs.opencv.org/3.4.5/d7/d9f/tutorial_linux_install.html
我在openCV上创建了一个构建目录，并使用了命令
cmake -DOPENCV_EXTRA_MODULES_PATH=<openCV contrib/modules> <openCV source directory>
此命令后一切正常：

我没有错误
但是当我尝试使用opencv2 / tracking.hpp从文档中获取代码时，却没有。我只有opencv2 / video / tracking。 如果我在https://docs.opencv.org/3.4.5/d2/d0a/tutorial_introduction_to_tracker.html上使用opencv2 / video / tracking运行代码，则跟踪器未定义。
我应该如何重新安装contrib模块才能获得opencv2 / tracking.hpp？我尝试了许多版本的openCV，并完成了许多教程...
谢谢

问题解决了！ 我不知道命令行出了什么问题，但是我通过本教程之后的界面下载了软件cmake：https://towardsdatascience.com/how-to-install-opencv-and-extra-modules-from-source-using-cmake-and-then-set-it-up-in-your-pycharm-7e6ae25dbac5 我删除了导致问题的opencv_features2D
然后
make
sudo make install
一切都与opencv2 / tracking.hpp配合使用
