i am trying to run this face recognition code from here!

i successfully installed OpenCV on the raspberry, and i used the code before on windows.

but here i have the problem with the raspberry camera module device ID, i tried the values 0-9 values for the ID , The Capture Device ID 0 cannot be opened. is all i get.

any help would be great. thank you

  • Have you enabled support for the camera module in raspi-config? – You'reAGitForNotUsingGit Apr 8 '16 at 19:07

Abdullah,

make sure you enable the camera module in raspi-config as Android Dev has suggested.

But also, in my experience, you need to run this in cmd line before the Raspi Camera can be used:

sudo modprobe bcm2835-v4l2

Run that line in cmd line and then try your application again. :)

  • it worked !!! :D that is awesome !! thank you very much , i have no idea how or why , but for that i thank you , been searching for hours now – Abdullah Ibdah Apr 8 '16 at 21:00
  • Any time. I too am working on an OpenCV project using the RPi & it's camera. Took me a while to find this answer myself. :) – Myg0t Apr 9 '16 at 17:59
  • can i ask you something . i think you to faced the long delay and small fps i assume , did you overcome that ? and how ? thank you again :D – Abdullah Ibdah Apr 10 '16 at 16:10
  • Are you trying to view the video live? I did face low FPS when I was streaming the video. If you record the video to a file and then view the file your FPS should be fine. – Myg0t Apr 12 '16 at 16:15
  • Actually I want it in real time , I am thinking the reason for the delay is the v4l2 because it runs on the processor unlike raspivid which runs on the GPU !! I am trying to stream a video into opencv ! Any thoughts ?! Thank you for your time – Abdullah Ibdah Apr 12 '16 at 16:20
