一、如何读取视频?
示例:pandas 是基于NumPy 的一种工具,该工具是为了解决数据分析任务而创建的。
二、使用步骤
1.引入库
代码如下(示例):
import cv2
cap=cv2.VideoCapture(r"C:\Users\liewei\Desktop\pic\1.mp4")
while(1):
ret,frame=cap.read()
gray=cv2.cvtColor(frame,cv2.COLOR_BGR2GRAY)
cv2.imshow("cap",frame)
if cv2.waitKey(27)&0xFF==ord('q'):#a按q暂停
break
cap.release()
cv2.destroyAllWindows()边栏推荐
