openCV:如何将视频分割成图像序列？

import cv2

def video_to_images(video_path, output_path):
    # 打开视频文件
    cap = cv2.VideoCapture(video_path)
    
    # 检查视频文件是否成功打开
    if not cap.isOpened():
        print("无法打开视频文件")
        return
    
    frame_count = 0
    
    while True:
        # 读取视频帧
        ret, frame = cap.read()
        
        # 检查是否成功读取帧
        if not ret:
            break
        
        # 保存帧为图像文件
        image_path = output_path + "/frame_" + str(frame_count) + ".jpg"
        cv2.imwrite(image_path, frame)
        
        frame_count += 1
    
    # 释放资源
    cap.release()

# 调用函数将视频分割成图像序列
video_to_images("path/to/video.mp4", "path/to/output_folder")
