SDARIT

FTL Labs’ SDARIT (Structural Damage and Repair Inferencing Tool) is a software application that ingests 3D point clouds such as those gathered via LIDAR as input and automatically detects damage and generates a repair part inventory for facilities including Navy pier assets. SDARIT will assist FTL’s Navy customer with pier damage assessment, especially in remote sites and with no prior design information. This is especially valuable in cases where sending a Subject Matter Expert (SME) to assess pier damage onsite is difficult, dangerous, and costly due to the wide range of pier locations and possible state of disrepair. With SDARIT, deployment of a LIDAR device by one or two technicians is all that is required to capture the data necessary to make a detailed report on the state of repair of any pier in any location. The software is designed to work with any point cloud data; LIDAR or even pier structures are not specifically required.

The SDARIT program’s primary objectives are to develop technology for the automatic detection of architectural elements for inventory purposes, together with damage detection and estimation based on the ingestion of 3D field survey data such as LIDAR point clouds and 360-degree videos. SDARIT utilizes both custom-trained neural networks and algorithmic solutions to meet these objectives, and the automatic pier element inventory and damage detection results are to be used by the Navy for estimation of required repair kits. The software is designed to detect and quantify certain types of damage such as scouring, breakages, spalling, section loss, and battle damage without requiring user input. The damage is visualized through a “heatmap” display and intuitive 3D fly-through of the data. In addition, 360-degree video captured along with the LIDAR data, if available, is aligned and viewed in the same interface, giving users access to both damage-highlighted 3D point cloud data and photographic verification anywhere on the structure. This data is saved and is rapidly browsable by remote subject matter experts from the safety of their offices and desktop computers.
