I'm using raspberry pi model 3, python 2.7, opencv 3.4.0 and picamera (connected to CSI port).
I want my camera to work at 100fps and more (I don't need high resolution at all, even something like 144p will go).
I tried running raspivid -w 320 -h 240 -fps 150 from console and it worked fine, means my camera is capable of working at 150 fps. But when I try to change camera.framerate to something more than 90fps it returns me error:
File "/home/pi/Desktop/January/March/03_22_picamera_lib_testing.py", line 6, in ><module>
camera.framerate=99
File "/usr/lib/python2.7/dist-packages/picamera/camera.py", line 2106, in _set_framerate
raise PiCameraValueError("Invalid framerate: %.2ffps" % value)
PiCameraValueError: Invalid framerate: 99.00fps
How can I fix this? Should I somehow modify picamera library?
Here's a code I wrote so far:
import cv2
from picamera import PiCamera
from picamera.array import PiRGBArray
camera=PiCamera()
camera.resolution=(640,480)
camera.framerate=99
rawCapture = PiRGBArray(camera, size=(640, 480))
for frame in camera.capture_continuous(rawCapture, format="bgr", use_video_port=True):
img = frame.array
cv2.imshow ('cam',img)
key = cv2.waitKey(1) & 0xFF
rawCapture.truncate(0)
if key == ord("q"):
break
