我想拍2张照片,但结果我先看了两张照片。我已经尝试将两个变量用于帧并将它们保存为文件。我该如何解决这个问题?
#!/usr/bin/python
import cv2
import time
cap = cv2.VideoCapture(0)
time.sleep(0.25)
ret1, t1 = cap.read()
print 'ret1:', ret1
cv2.imshow('test',t1)
cv2.waitKey(0)
ret1, t1 = cap.read()
print 'ret1:', ret1
cv2.imshow('test1',t1)
cap.release()
while True:
time.sleep(1)
if cv2.waitKey(1) == 27:
break
cv2.destroyAllWindows()
