project due in 3 days, pls help - Raspberry Pi Forums

we have code capture 1 image, , perform image processing techniques.
however, need capture image every 10 seconds. since noobs don't know how it. can pls us.

enclosed whole program inside while loop. program runs fine in first iteration. throws error next time.

code: select all

from picamera.array import pirgbarray picamera import picamera import time import cv2 import numpy np import rpi.gpio gpio while true: # initialize camera , grab reference raw camera capture     camera = picamera()     camera.resolution = (320, 240)     rawcapture = pirgbarray(camera)   # allow camera warmup     time.sleep(0.1) # grab image camera           camera.capture(rawcapture, format="bgr")     image = rawcapture.array     cv2.imshow("image",image)     cv2.imwrite("captured.jpeg",image)     image = cv2.imread('captured.jpeg',0)     ret,thresh1 = cv2.threshold(image,127,255,cv2.thresh_binary)     cv2.imwrite("captured_thresh.jpeg",thresh1)     img = cv2.imread("captured_thresh.jpeg")     blue_min = np.array([0, 0, 0], np.uint8)     blue_max = np.array([50, 50, 50], np.uint8)     dst = cv2.inrange(img, blue_min, blue_max)     no_blue = cv2.countnonzero(dst)     if no_blue>1000000:         gpio.setmode(gpio.bcm)         gpio.setup(14,gpio.out)         gpio.output(14,gpio.high)     print('the number of blue pixels is: ' + str(no_blue))     time.sleep(10)      

getting following error

code: select all

the number of blue pixels is: 66978 mmal: mmal_vc_component_enable: failed enable component: enospc traceback (most recent call last):   file "count1.py", line 9, in <module>     camera = picamera()   file "/home/pi/.virtualenvs/cv/local/lib/python3.4/site-packages/picamera/camera.py", line 488, in __init__     self.stereo_modes[stereo_mode], stereo_decimate)   file "/home/pi/.virtualenvs/cv/local/lib/python3.4/site-packages/picamera/camera.py", line 620, in _init_camera     prefix="camera component couldn't enabled")   file "/home/pi/.virtualenvs/cv/local/lib/python3.4/site-packages/picamera/exc.py", line 191, in mmal_check     raise picamerammalerror(status, prefix) picamera.exc.picamerammalerror: camera component couldn't enabled: out of resources (other memory) 

try moving code

code: select all

camera = picamera() camera.resolution = (320, 240) rawcapture = pirgbarray(camera) 

before while loop

suspect camera doesn't being initialized twice.
