Dear all,
I'm on lubuntu 16.04, using OpenCV 3.2.0, Python 2.7 and encountering this error after a brief moment of imshow() displaying a window with my camera stream.
**ASSERT: "false" in file qasciikey.cpp, line 495
Aborted (core dumped)**
My code appended below:
import numpy as np
import cv2
redcross_cascade = cv2.CascadeClassifier('rcrosscascade.xml')
cap = cv2.VideoCapture(2)
cv2.namedWindow('Haar', cv2.WINDOW_NORMAL)
while 1:
ret, img = cap.read()
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
redcross = redcross_cascade.detectMultiScale(gray, 50, 50)
for (x,y,w,h) in redcross:
cv2.rectangle(img,(x,y),(x+w,y+h),(255,255,0),2)
cv2.imshow('Haar',img)
key = cv2.waitKey(1) & 0xff
if key == 27:
break
cap.release()
cv2.destroyAllWindows()
Would appreciate any assistance on this matter, thank you!
