Intersection position model construction method for three-dimensional highway or railway route selection
A railway and intersection technology, applied in the field of three-dimensional automatic line selection, can solve the problems that design parameters cannot change with terrain changes, there is no absolute relationship, and automatic line selection is difficult to apply in practice

[0069] The present invention will be further described below in conjunction with examples and accompanying drawings.
[0070] A method for constructing intersection positions for three-dimensional route selection of highways or railways, comprising the following steps:
[0071] Step 1: Build a plane cutting line model, such as figure 1 shown;
[0072] 1.1) Set the starting point of the plane cutting line S(x S ,y S ) and end point E(x E ,y E ), get the connection S(x S ,y S ) and E(x E ,y E ) segment
[0073] 1.2) Set the initial number of intersection points of the plane to n P , n P root perpendicular to plane cutting line Will divided into n P +1 segment, O 1 ,O 2 ,...,O np Respectively, the intersection point of the plane cutting line and the line segment SE, and the intersection point of the horizontal curve are located on the plane cutting line Q 1 ,Q 2 ,...,Q np On, the intersection point O of the plane cutting line and the line segment SE i...
