Fast picamera image analysis

[14henderson]

Does anyone know how to capture images from the picamera at fast speeds and convert it into a format that PIL can interpret? At the moment I'm using their suggested code (from http://picamera.readthedocs.org/en/latest/recipes1.html), but I can only get it to take an image every second - which is at least 10 times too slow for my needs. I'm sort of new to all this, so if you explain your answers as much as possible that would be much appreciated.

The code I'm currently using:
stream = io.BytesIO()
with picamera.PiCamera() as camera:
camera.start_preview()
camera.capture(stream, format='jpeg')
stream.seek(0)
image = Image.open(stream)

Maybe using the raspberry pi camera to stream a video recording and then taking frames from the stream would work? Someone help!

Have a look here http://picamera.readthedocs.org/en/rele ... ipes2.html and scroll down to "Rapid capture and processing".
Maybe set up a RAM disk to make things quicker. Don't know about processing on-the-fly but this is a start.

Can you do the processing (or some of it) in numpy/scipy?
