python - 使用Python拍照

Question

我正在尝试使用两台相机中的一台拍照(Surface book 2) 首先，我想拍照，然后尝试使用前置和后置摄像头拍照 我找不到怎么拍照... 尝试使用pygame.camera 但出现错误

Traceback (most recent call last):
  File "C:\Program Files\Python37\lib\site-packages\pygame\_camera_vidcapture.py", line 31, in init
    import vidcap as vc
ModuleNotFoundError: No module named 'vidcap'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    pygame.camera.init()
  File "C:\Program Files\Python37\lib\site-packages\pygame\camera.py", line 69, in init
    _camera_vidcapture.init()
  File "C:\Program Files\Python37\lib\site-packages\pygame\_camera_vidcapture.py", line 33, in init
    from VideoCapture import vidcap as vc
ModuleNotFoundError: No module named 'VideoCapture'

不知道如何解决这个问题，如果您知道如何选择哪个相机来拍摄照片，那就太棒了:)

尝试一下 OpenCV 怎么样。像这样的吗？

我还没有对此进行测试，但它应该可以帮助您开始从相机中提取帧。另请记住，安装是针对 opencv-python 包的。

import cv2
import numpy as np

cap = cv2.VideoCapture(0) # I am using my internal laptop webcam

while(1):
    ret, frame = cap.read()

    # Show frame
    cv2.imshow('MyWindow', frame)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

#Destroy the capture session
cap.release()
cv2.destroyAllWindows()
