python+opencv 图像序列转视频

import cv2
import glob 
import os 
img_root = "home/png/" # 是图片序列的位置
fps = 30  # 可以随意调整视频的帧速率

#可以用(*'DVIX')或(*'X264'),如果都不行先装ffmepg
fourcc = cv2.VideoWriter_fourcc(*'XVID')
videoWriter = cv2.VideoWriter('Video.avi',fourcc,fps,(1280,720),True)#(1280,720)是图像序列的尺寸，True指保存为彩色视频，false为灰度视频
j = 0
for i in sorted(glob.glob(os.path.join(img_root, '*.png'))):
    j = j+1
    frame = cv2.imread(i)
    print('-> load {} picture'.format(j))
    videoWriter.write(frame)
videoWriter.release()
cv2.destroyAllWindows()
