用python写一个程序计算在三维空间求点到直线的最短距离

我可以为你提供一个简单的python程序，用来计算三维空间中点到直线之间的最短距离。代码如下：from numpy import *
def point_to_line(point, line):
point = array(point)
line_start, line_end = line
line_start = array(line_start)
line_end = array(line_end)
line_vec = line_end - line_start
point_vec = point - line_start
line_unitvec = line_vec / linalg.norm(line_vec)
point_vec_scaled = line_unitvec * dot(line_unitvec, point_vec)
nearest_point = line_start + point_vec_scaled
return linalg.norm(nearest_point - point)
