假设我有两个多边形,它们的名称和坐标为:
p:[(1,1),(2,2),(4,2),(3,1)]
q:[(1.5,2),(3,5),(5,4),(3.5,1)]
在我们的大脑中,很容易知道这两个多边形相交并计算了相交区域的坐标,但是我想让我们的机器知道如何计算相交区域的坐标。基本上,我想知道是否有一个简单明了的算法来完成这项工作,如果已经有一个python库可以做到这一点,那将是完美的。

from shapely.geometry import Polygon
p = Polygon([(1,1),(2,2),(4,2),(3,1)])
q = Polygon([(1.5,2),(3,5),(5,4),(3.5,1)])
print(p.intersects(q)) # True
print(p.intersection(q).area) # 1.0
x = p.intersection(q)
print(x) #POLYGON ((1.833333333333333 1.833333333333333, 2 2, 4 2, 3.166666666666667 1.166666666666667, 1.833333333333333 1.833333333333333))
