A method for build a database of vehicle pass height limit using ground-based laser measurement data

摘要

The present invention relates to a method for constructing a database for limiting the passage height of a vehicle using terrestrial laser surveying data, in which a position corresponding to an intersection of a road or a railroad is searched in a map database and a height of an intersection corresponding to a position searched in the terrestrial laser surveying data The present invention relates to a method of constructing a database for limiting the passage height of a vehicle using terrestrial laser surveying data for extracting a vehicle passing through the intersection and constructing a vehicle passing limit height at the intersection.A method for constructing a database for limiting the passage height of a vehicle using terrestrial laser measurement data according to the present invention includes a first step of extracting an intersection point of linear data in map data at an intersection point extracting unit and a second step of extracting an intersection point height of the intersection point extracted at the intersection point extracted by the intersection point extracting unit A second step of extracting a corresponding screen area from the laser survey data; and the intersection height extracting part extracts a screen area corresponding to one position between the first area below the intersection and the second area above the intersection, A step of generating one or more height information of the intersection lower limit area, and a step of generating height information of the smallest vertical direction among the one or more calculated height information to the vehicle passing limit height of the intersection lower end area, There is a technical significance in including 4 steps.;
