End-to-End Development, Design and Implementation of a Crack Detection System for Tunnels and Other Underground Transportation Infrastructure

Structural monitoring of the tunnel lining is of paramount importance for a multitude of reasons including (1) detection of initial defects and control of costs during construction; (2) continuous monitoring during operation to ensure integrity, safety, and control of costs via incremental repairs and timely interventions; and (3) determination of the level of safety to inform system-level risk assessment and performance analysis. The overall goals of the project are to: 1) Build a hardware platform for image and data acquisition then use this platform to explore and assess various alternative data acquisition techniques with an eye first to functionality and reliability first and second to cost; 2) Develop and build vehicle mounted data acquisition system with consideration for operational aspects; 3) Develop and build a system for geospatial localization within tunnels or other underground structures; 4) Develop and build a system for tagging data location; and 5) Develop and build a fully automated machine learning system for post-processing of the acquired image database for crack detection.
