这里用的OpenCV这个库
直接看下面简单拍照demo
import cv2
cap = cv2.VideoCapture(0)
while(1):
# get a frame ret,
frame = cap.read()
# show a frame
cv2.imshow("capture", frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
cv2.imwrite("C:/Users/pc/Desktop/icon/fangjian2.jpeg", frame)
break
cap.release()cv2.destroyAllWindows()
这里是按q拍照退出。
再来个视频的demo
# coding:utf-8import cv2import sys
reload(sys)
sys.setdefaultencoding('utf8')
cap = cv2.VideoCapture(0)
cap.set(3,640)
cap.set(4,480)
cap.set(1, 10.0)
#此处fourcc的在MAC上有效，如果视频保存为空，那么可以改一下这个参数试试, 也可以是-1
fourcc = cv2.cv.CV_FOURCC('m', 'p', '4', 'v')#python2.x
# fourcc = cv2.VideoWriter_fourcc(*'MJPG') #python3.x
# 第三个参数则是镜头快慢的，10为正常，小于10为慢镜头
out = cv2.VideoWriter('/opt/code/video/output2.avi', fourcc,10,(640,480))
while True:
ret,frame = cap.read()
if ret == True:
frame = cv2.flip(frame, 1)
a = out.write(frame)
cv2.imshow("frame", frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break else:
breakcap.release()
out.release()
cv2.destroyAllWindows()
