如何将yolov8的图像通过 uvc-gadget输出

from ultralytics import YOLOimport cv2# 加载模型model = YOLO('yolov8n.pt')# 预测（不自动保存）results = model('input.jpg', save=False)# 获取带标注的图片（numpy数组）annotated_frame = results[0].plot()  # 绘制所有检测框# 保存为JPGcv2.imwrite('output.jpg', annotated_frame)# 或转换为RGB后保存（OpenCV默认BGR）from PIL import Imagergb_frame = cv2.cvtColor(annotated_frame, cv2.COLOR_BGR2RGB)Image.fromarray(rgb_frame).save('output_rgb.jpg', quality=95)
