Saya telah mencoba menginstal opencv dari sumber daripada pip karena saya tidak berhasil membaca VideoCapture.

Memasang opencv-3.2.0 di Ubuntu 16.04.3 LTS. Ikuti detail yang disebutkan di sini.

Saya mendapatkan kesalahan berikut di ".../opencv-3.2.0/build/CMakeFiles/CMakeError.log":

.../opencv-3.2.0/build/CMakeFiles/CMakeTmp/CheckIncludeFile.c:1:28: fatal error: linux/videodev.h: No such file or directory


.../opencv-3.2.0/build/CMakeFiles/CMakeTmp/CheckIncludeFile.c:1:25: fatal error: sys/videoio.h: No such file or directory

libv4l-dev sudah menjadi versi terbaru (1.10.0-1)

Saya juga menjalankan perintah berikut di /usr/include/linux:

sudo ln -s ../libv4l1-videodev.h videodev.h

Keluaran CMake adalah:

Jawaban Terbaik

Ini tampaknya sangat konyol dalam retrospeksi tetapi perintah cmake memiliki opsi jalur untuk -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.2.0/modules \. Jalur ini salah di sistem saya. Saya mengubahnya ke jalur yang benar dan berhasil. Terima kasih untuk semua bantuan teman-teman!

Untuk masalah Anda, Anda harus menjalankan perintah berikut

sudo apt-get install libv4l-dev

Untuk menginstal OpenCV di Ubuntu, saya selalu mengikuti beberapa langkah yang selalu berhasil.

Saya menginstal OpenCV dengan opencv_contrib (beberapa modul tambahan untuk OpenCV)

Buka terminal dan jalankan perintah berikut

Untuk menginstal ketergantungan opencv

sudo apt-get install build-essential

sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev

sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

sudo apt-get install libxvidcore-dev libx264-dev

Untuk menginstal opencv

  1. cd /opt/

  2. sudo git clone https://github.com/opencv/opencv.git

  3. sudo git clone https://github.com/opencv/opencv_contrib.git

  4. cd opencv

  5. rilis sudo mkdir

  6. rilis cd

  7. Sudo cmake -D CMAKE_INSTALL_PREFIX=/usr/local -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D OPENCV_EXTRA_MODULES_PATH=/opt/opencv_contrib/modules -D WITH_LIBV_LIBV_EXTRA_MODULES_PATH=/opt/opencv_contrib/modules -D WITH_LIBV4L=ON -Dopt

  8. sudo membuat

  9. sudo make install

  10. pkg-config --modversion opencv # periksa versi yang diinstal

Jika Anda tidak ingin menginstal opencv_contrib, Anda dapat melewati langkah ke-3 dan mengubah langkah ke-7 menjadi

sudo cmake -D CMAKE_BUILD_TYPE=RELEASE -D 
CMAKE_INSTALL_PREFIX=/usr/local -D /opt/opencv/
