Hi, I would like to use the Udoo camera with OpenCV and Python. Essentially, I'm getting the exact same problem, and looking for a solution for the exact same problem as in this thread: http://www.udoo.org/forum/threads/using-udoo-camera-with-opencvs-videocapture-class.1807/#post-11682 It looks like the solution was to use the loopback device so I can use the Udoo's camera as a normal webcam. Oh but wait... it's been deprecated in UDOObuntu 2.1: http://www.udoo.org/docs/Hardware_&_Accessories/UDOO_Camera_Module.html "Warning! This following Loopback Device section is deprecated since UDOObuntu 2.0. It is present only in UDOObuntu 1.0/1.1 versions.", and indeed I don't think the kernel module is present in my UDOObuntu build. Is there a way to access the Udoo camera in python/openCV/like a normal USB webcam in UDOObuntu 2.1? Is a rollback the only solution? -- Justyn
Hi there Justyn, the feature was under development, but we left it behind for reasons of time. If you are in the mood of trying to develop it yourself, here there may be something useful: http://trac.gateworks.com/wiki/Yocto/gstreamer/video
If anyone stumbles upon this, I got video/image capture working in OpenCV by building OpenCV from source (3.1 at this time), with the following cmake flags -D CMAKE_CXX_FLAGS="-Wa,-mimplicit-it=thumb" -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_GTK=ON -D WITH_OPENGL=ON Obviously, there's some dependencies there, such as gtk2.0. Then the following Python code works: import cv2 camera = cv2.VideoCapture(0) while True: return_value,image = camera.read() gray = cv2.cvtColor(image,cv2.COLOR_BGR2GRAY) cv2.imshow('image',gray) if cv2.waitKey(1)& 0xFF == ord('s'): cv2.imwrite('test.jpg',image) break camera.release() cv2.destroyAllWindows()
