PROJECT DATA:

DESCRIPTION: This project will develop a novel framework that automatically converts 3D dense point clouds, obtained from 2D digital images collected using an UAS, into 3D BrIM.

The framework will make it much more convenient and faster to implement 3D BrIM, thus improve the current bridge inspection and management practice in terms of efficiency and safety. Computer vision algorithms will be used to segment and label bridge components automatically using deep learning techniques.

The anticipated outcomes of this research will be to a) provide a trained model that enables to automatically identify and label bridge elements from their 3D point clouds; b) speed up the transition from 2D to 3D format in bridge inspection and management practices; c) increase the adoption of 3D BrIM for maintenance phase of infrastructure projects. All of these factors should help assist in maintaining U.S. bridges in a state of good repair, thus help ensure public mobility.
