Hello, I'm trying to counting vehicle, but I can't increasing it, I use
python 2.7.6 and opencv 2.4.9
I don;t understand what you mean.
There is no vehicle in your code?
The code is overly complex for me to read through and it uses a module
that I don't have so I'm not even attempting to run it... And it looks
like it has a syntax error too - an if block missing.
Can you provide more details about what is happening?
Also try inserting some print statements so that you can
see what your code is doing.
That way you might see the problem yourself.
import cv2
bgsMOG = cv2.BackgroundSubtractorMOG2(500,30,True)
cap = cv2.VideoCapture("d:\MOV_5680.avi")
counter =0
if cap:
while True:
ret, frame = cap.read()
if ret:
fgmask = bgsMOG.apply(frame, None, 0.01)
cv2.line(frame,(20,170),(320,170),(175,175,0),1)
contours, hierarchy = cv2.findContours(fgmask,
cv2.RETR_EXTERNAL,cv2.CHAIN_APPROX_SIMPLE)
ax1=20 #coordinate of line where vehicle will be count
if intersect
ay1=170
ax2=320
ay2=170
try: hierarchy = hierarchy[0]
except: hierarchy = []
for contour, hier in zip(contours, hierarchy):
(x,y,w,h) = cv2.boundingRect(contour)
if w > 10 and h > 15:
cv2.rectangle(frame, (x,y), (x+w,y+h), (180, 0, 0), 1)
x1=w/2 #to find centroid
y1=h/2
cx=x+x1
cy=y+y1
centroid=(cx,cy)
cv2.circle(frame,(int(cx),int(cy)),1,(0,255,0),-1)
dy=cy-170 #my first code to increase counter
if dy==0:
if (cx<=320)and(cx>=70):
counter=counter+1
if cy==170:
cv2.putText(frame, str(counter),(10,150),
cv2.FONT_HERSHEY_SIMPLEX,2, (255, 0, 0), 1, True)
#cv2.namedWindow('Output',cv2.cv.CV_WINDOW_NORMAL)
#cv2.resizeWindow('Output',320,180)
cv2.imshow('Output', frame)
cv2.imshow('FGMASK', fgmask)

if key == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
