I am working on a project that can display phone cam display on pc. For this task I am using the infamous python module Cv2 and numpy. But for some reason Cv2 functions aint working. Any kind of help would be welcome. Regards, Odysseus
My code:
import urllib.request
import numpy as np
# import time
from cv2 import __all__
cv2 = __all__
URL = "http://myip/shot.jpg"
while True:
img_arr = np.array(bytearray(urllib.request.urlopen(URL).read()), dtype=np.uint8)
img = cv2.imdecode(img_arr, -1)
cv2.imshow('IPWebcam', img)
q = cv2.waitKey(1)
if q == ord("q"):
break
cv2.destroyAllWindows()
The error:
Traceback (most recent call last):
File "C:\Users\name\PycharmProjects\cam\df.py", line 10, in <module>
img = cv2.imdecode(img_arr, -1)
AttributeError: 'list' object has no attribute 'imdecode'
You tried to import OpenCV using this:
from cv2 import __all__
cv2 = __all__
That is entirely wrong . __all__
is nothing but a list of all the names of all the defined functions and whatnot. That in itself is useless if you want to use the library.
Simply do this:
import cv2 as cv
And then use like so: cv.imdecode(...)
Change your img to:
img = cv2.imdecode(np.frombuffer(img_arr, dtype=np.uint8), cv2.IMREAD_COLOR)
