提及的YOLO坐标的格式为：x_center，y_center，width_box，height_box，标准化wrt图像高度和宽度。您可以使用以下命令将其转换为绘制矩形的标准/常用格式：

x = x_center * image_width
y = y_center * image_height
w = width_box * image_width
h = height_box * image_height

如果您希望边框格式为：x最小值、y最小值、x最大值、y最大值，然后：

xmin = int(x - width_box/2)
ymin = int(y - height_box/2)
xmax = int(x + width_box/2)
ymax = int(y + height_box/2)

你可以这样做〉〉

import cv2, os

image = cv2.imread('/file/path.ext')
lh,lw,_ = image.shape

# now take your coordinates
x,y,w,h = 0.514583, 0.716204, 0.136458, 0.102778
x,y,w,h = int(x*lw), int(y*lh), int(w*lw), int(h*lh) ## to match the bounding box coordinates with actual width, height

boxedImage = image[y:y+h, x:x+w]
cv2.imshow(boxedImage)

希望这有帮助!
