Embodiment Construction
[0095] The invention provides a road network selection method integrating line and plane modes, comprising the following steps:
[0096] 1), the least square method (OLS, ordinary least square) is a parameter estimation model that obtains the best fitting straight line from scattered points, and this model minimizes the sum of squares of scattered points and fitting straight line as a whole. Therefore, this technical solution uses the OLS model to calculate the slope rate of the road section to be connected, and combines the angle of the connection to design a Stroke connection rule that takes into account the whole. Stroke can be regarded as a path composed of several continuous road segments. The slope rate of the path obtained by the OLS model is essentially the slope obtained by simulating the nodes on the path, which can represent the relationship between the subsequent connecting road sections and the initial road section. After the introduction of the OLS model, taking...
