yolov8模型预测

使用OpenCV和YOLOv8模型在视频帧上进行推理的代码如下所示：

import cv2
from ultralytics import YOLO

# 加载YOLOv8模型
model = YOLO('yolov8n.pt')

# 打开视频文件
video_path = "path/to/your/video/file.mp4"
cap = cv2.VideoCapture(video_path)

# 循环遍历视频帧
while cap.isOpened():
    # 从视频中读取一帧
    success, frame = cap.read()
    
    if success:
        # 在帧上运行YOLOv8推理
        results = model(frame)
        
        # 在帧上可视化结果
        annotated_frame = results<span class="em">1</span><span class="em">2</span><span class="em">3</span>
