代码一
import cv2
import os
#要提取视频的文件名，隐藏后缀
sourceFileName='../wurenji_putao/DJI_0009'
#在这里把后缀接上
video_path = os.path.join("", "", sourceFileName+'.MP4')
times=0
#提取视频的频率，每25帧提取一个
frameFrequency=25
#输出图片到当前目录vedio文件夹下
outPutDirName=''+sourceFileName+'/'
if not os.path.exists(outPutDirName):
#如果文件目录不存在则创建目录
os.makedirs(outPutDirName)
camera = cv2.VideoCapture(video_path)
while True:
times+=1
res, image = camera.read()
if not res:
print('not res , not image')
break
if times%frameFrequency==0:
cv2.imwrite(outPutDirName + str(times)+'.jpg', image)
print(outPutDirName + str(times)+'.jpg')
print('图片提取结束')
camera.release()
代码二:
import cv2
vidcap = cv2.VideoCapture('../wureji_putao/DJI_0009.MP4')
success,img = vidcap.read()
count = 0
success = True
while success :
success,image = vidcap.read()
cv2.imwrite("frame%d.jpg" % count, image)
if cv2.waitKey(10) == 27:
break
count += 1
代码三：
import cv2
vc = cv2.VideoCapture('../wurenji_putao/DJI_0010.MP4') # 读入视频文件，命名cv
n = 1 # 计数
if vc.isOpened(): # 判断是否正常打开
rval, frame = vc.read()
else:
rval = False
timeF = 10 # 视频帧计数间隔频率
i = 259
while rval: # 循环读取视频帧
rval, frame = vc.read()
if (n % timeF == 0): # 每隔timeF帧进行存储操作
i += 1
print(i)
cv2.imwrite('../wurenji_putao/DJI_0010/{}.jpg'.format(i), frame) # 存储为图像
n = n + 1
cv2.waitKey(1)
vc.release()
