如何从轴对齐的边界框中获取矩形倾斜度？

import math

def get_rectangle_skewness(bbox):
    # 计算矩形的宽度和高度
    width = bbox[2] - bbox[0]
    height = bbox[3] - bbox[1]

    # 确定长边和短边
    if width > height:
        long_side = width
        short_side = height
    else:
        long_side = height
        short_side = width

    # 计算长宽比例
    aspect_ratio = long_side / short_side

    # 计算矩形的倾斜度
    skewness = math.atan(aspect_ratio)

    return skewness
