在opencv中使用video.write从图像创建mp4文件

import cv2
import os

# 设置视频编码格式和输出文件名
fourcc = cv2.VideoWriter_fourcc(*'mp4v')
output_file = 'output.mp4'

# 设置视频分辨率和帧率
frame_width = 640
frame_height = 480
fps = 30

# 创建 VideoWriter 对象
video_writer = cv2.VideoWriter(output_file, fourcc, fps, (frame_width, frame_height))

# 假设图像序列存储在 images 文件夹中
image_folder = 'images'
image_files = sorted([os.path.join(image_folder, img) for img in os.listdir(image_folder) if img.endswith('.jpg')])

for image_file in image_files:
    # 读取图像
    frame = cv2.imread(image_file)
    if frame is not None:
        # 写入视频
        video_writer.write(frame)

# 释放 VideoWriter 对象
video_writer.release()
