所以我试图在python 2.7.5上创建一个简单的程序,窗口就是这样 显示用户选择时间的实时视频。
import numpy as np
import cv2
import time
def Func_VideoCapture(Float_Time = 10):
Float_WantedTime = time.time() + Float_Time
Float_CurentTime = time.time()
cap = cv2.VideoCapture(0)
while Float_CurentTime <= Float_WantedTime:
#get current time
Float_CurentTime = time.time()
# Capture frame-by-frame
ret, frame = cap.read()
# Display the resulting frame
cv2.imshow('frame',frame)
# When everything done, release the capture
cap.release()
cv2.destroyAllWindows()
if __name__ == "__main__":
Float_Time = float(raw_input(">>> "))
Func_VideoCapture(Float_Time)
但是当我运行它时会出现一个对话框,要求我弹出相机(视频源 - &gt;捕获源)。 如何将其隐藏起来? 附:我也尝试过运行......
cap = cv2.VideoCapture(0)
...在主函数中但结果是相同的:
import numpy as np
import cv2
import time
def Func_VideoCapture(cap, Float_Time = 10):
Float_WantedTime = time.time() + Float_Time
Float_CurentTime = time.time()
while Float_CurentTime <= Float_WantedTime:
Float_CurentTime = time.time()
# Capture frame-by-frame
ret, frame = cap.read()
# Display the resulting frame
cv2.imshow('frame',frame)
# When everything done, release the capture
cap.release()
cv2.destroyAllWindows()
def main():
cap = cv2.VideoCapture(0)
Float_Time = float(raw_input(">>> "))
Func_VideoCapture(cap, Float_Time)
if __name__ == "__main__":
main()
P.S.#2我在Windows上,但我不一定要使用这个版本的python或OpenCV
答案 0 :(得分:-1)
试试这个:
import numpy as np
import cv2
import time
def Func_VideoCapture(Float_Time = 10):
Float_WantedTime = time.time() + Float_Time
Float_CurentTime = time.time()
cap = cv2.VideoCapture(0)
while Float_CurentTime<=Float_WantedTime:
#get current time
Float_CurentTime = time.time()
# Capture frame-by-frame
ret, frame = cap.read()
# Display the resulting frame
cv2.imshow('frame',frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
# When everything done, release the capture
cap.release()
cv2.destroyAllWindows()
if __name__ == "__main__":
Float_Time = float(raw_input(">>> "))
Func_VideoCapture(Float_Time)
