python调用opencv实现读取摄像头逐帧转为图片
import cv2
import os
def register_face(filepath):
cap =cv2.VideoCapture(0)
i=1
while(i<51):#读取50张图片
ret , frame =cap.read()
cv2.imshow('frame',frame)
cv2.imwrite(filepath+"\\"+os.path.split(filepath)[1]+"_"+str(i)+".jpg",frame)
print(filepath+"\\"+os.path.split(filepath)[1]+"_"+str(i)+".jpg")
i = i+1
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
