為了自己做資料集今天學習了一項新技能！
程序極簡單直接上代碼
# 視頻分解圖片
# from PIL import Image
import cv2
cap = cv2.VideoCapture("7.mp4")# 獲取當前路徑下的視頻打開cap 1 file name
isOpened = cap.isOpened# 判斷是否打開‘
print(isOpened)
fps = cap.get(cv2.CAP_PROP_FPS)#幀率
width = int(cap.get(cv2.CAP_PROP_FRAME_WIDTH))#w h
height = int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT))
print(fps,width,height)
i = 0
while(isOpened):
if i == 200:#第200張結束，自行調節，
break
else:
i = i+1
(flag,frame) = cap.read()# 讀取每一張 flag frame
fileName = 'img//in//'+str(i+990)+'.jpg'
print(fileName)
if flag == True:
cv2.imwrite(fileName,frame,[cv2.IMWRITE_JPEG_QUALITY,100])
# 可以調整圖片大小
# path='img//in//'+'0'+str(i)+'.jpg'
# root = path
# pic = Image.open(root)
# pic = pic.resize((512, 512))
# pic.save(path)
print('finish!')
