如何计算边界框的中心? [英] How to calculate the center of the bounding box?

问题描述

我正在尝试使用这些给定的点来计算边界框的中心

Im trying to calculate the center of the bounding box with these given points

(50.607041876988994, -1.3187316344406208, 52.40735812301099, 1.5737316344406207)

已解决编辑问题:这是我在python中完成的代码

Edit Solved : This is the code i done in python

from math import cos, sin, atan2, sqrt

    def center_geolocation(geolocations):
        """
        Provide a relatively accurate center lat, lon returned as a list pair, given
        a list of list pairs.
        ex: in: geolocations = ((lat1,lon1), (lat2,lon2),)
            out: (center_lat, center_lon)
        """
        x = 0
        y = 0
        z = 0

        for lat, lon in geolocations:
            lat = float(lat)
            lon = float(lon)
            x += cos(lat) * cos(lon)
            y += cos(lat) * sin(lon)
            z += sin(lat)

        x = float(x / len(geolocations))
        y = float(y / len(geolocations))
        z = float(z / len(geolocations))

        return (atan2(y, x), atan2(z, sqrt(x * x + y * y)))

谢谢:)

推荐答案

在您给出的示例中没有浮动错误....我不喜欢输出-但这不是问题.

There is not float error in the example you have given .... I do not like the output - but that was not the question.
