This video tells the step how to install OpenCV and Python 2.7. Sorry that in this video it says show, but I just tell the steps as I already installed OpenCV and Python 2.7, uninstalling. Is there a way i can download wow for mac os x 10.9?.
Python -m pip install opencv-python also works for certain ARM platforms like the Raspberry Pi. Note: If you install on an ARMv7 Raspberry Pi (or ARMv8 running in ARMv7 e.g.
With Raspbian), you will need to pip uninstall and pip install upon inserting the SD card into an ARMv6 system, or SIGILL Illegal Instruction error will result. An example of this is setting up a Python OpenCV algorithm on a Raspberry Pi 2/3/3+, then inserting the same SD card into a Raspberry Pi 0/0W/1 will require reinstalling OpenCV–this is trivial and fast to do. OpenCV with extra contribs For those desired the latest extended functionality that hasn’t yet been incorporated into the core package, OpenCV including the may be obtained. C: anaconda3 scripts python -m pip install opencv-python Test Python OpenCV install We made several test to try out the OpenCV install. Compile source You can OpenCV for Python. Or compile OpenCV with. Compiling yourself allows customizing and optimizing OpenCV for your computer (e.g.
Using GPU, TBB, OpenCL, etc.). Conda The conda install opencv and conda install -c conda-forge opencv methods for OpenCV continue to be BROKEN for video/image reading and display.
Use pip install above instead. Tags:,, Categories: Written by Michael Hirsch, Ph.D. // 2018-08-30.
I am doing video streaming by using VideoCapture(0). There are two scripts:main.py(use for get the frame). Camera.py(use for return the frame captured by camera) The system is deployed in Flask. Here is my camera script:%camera.py import cv2 class VideoCamera(object): def __init__(self): print 'before video success!' Self.video = cv2.VideoCapture(1) *it stuck at this line! Print 'after video success!' Self.video.set(3,320) self.video.set(4,240) self.video.set(15, 0.1) def __del__(self): self.video.release() def get_frame(self): success, image = self.video.read() ret, jpeg = cv2.imencode('.jpg', image) return jpeg.tobytes() There is no error,just print 'before video success!'
And stuck at this line!
