pythonpolygonpoint-in-polygon 4 我正在尝试检测一个给定的点(x,y)是否在一个n*2数组的多边形内。但是似乎一些位于多边形边界上的点会返回不包括在内的结果。 def point_inside_polygon(x,y,poly): n = len(poly) inside =False p1x,p1y = poly[0] for i in range(n+1): p2x,p2y = poly[i %...
安装必要的库导入所需的模块创建Point对象使用Point对象创建Polygon对象验证Polygon对象的正确性可视化Polygon 结论 通过上面的步骤,我们成功地使用Python的shapely库将一系列点连接成一个多边形,并通过matplotlib进行可视化。在实际开发中,这种操作在地图绘制、空间分析等领域非常常见。希望本指南能够帮助您更好地理解Python中Po...

laspy是一个基于python的读写LAS/LAZ文件的开源库。 PDAL PDAL是一个基于C++的处理点云数据的开源库,提供python接口。 Shapely Shapely是一个基于python的处理几何的工具,很强大,如能处理带洞的多边形等。 Other 这下面主要是商业软件,很多都是处理整个流程的。
