AUTOMATED BIM CONSTRUCTION SYSTEM AND METHOD OF RAILWAY BRIDGE

摘要

The present invention relates to an automated BIM construction system and method of a railway bridge, and the automated BIM construction system of a railway bridge according to an embodiment of the present invention performs 3D measurement of lidar on an existing railway bridge, which is a target structure. A lidar measurement unit that acquires 3D point cloud data, the 3D point cloud data, which is shape information obtained from the lidar measurement unit, is recognized as each object constituting a railway bridge through a deep learning algorithm When the deep learning object recognition unit, when the shape information obtained from the lidar measurement unit is recognized and classified as a unit object to be modeled by the deep learning object recognition unit, an object parameter extraction unit that extracts parameters for each object constituting the railway bridge, the It includes a modeling unit that performs BIM (Building Information Modeling) modeling based on the parameters extracted from the object parameter extraction unit, and a BIM construction unit that builds the BIM of the railway bridge modeled by the modeling unit.
