yolov5摄像头问题汇总_为什么yolo调用的摄像机特别卡

view-img参数的作用

如图加入三行print

if webcam:
    print("test place 1")
    print(view_img)
    view_img = check_imshow()
    print(view_img)
    cudnn.benchmark = True  # set True to speed up constant image size inference
    dataset = LoadStreams(source, img_size=imgsz, stride=stride, auto=pt)
    bs = len(dataset)  # batch_size
else:
    dataset = LoadImages(source, img_size=imgsz, stride=stride, auto=pt)
    bs = 1  # batch_size
vid_path, vid_writer = [None] * bs, [None] * bs

输入

python detect.py --source 1 --weights yolov5s.pt --device 0
1

输入：

python detect.py --source 1 --weights yolov5s.pt --device 0 --view-img
1

可见只要webcam is True，进入这个if后不管view-img之前是不是True，都会被check_imshow()改为True。
