Reducing Costs with LiDAR

Problem• Although physical LiDAR scans costs have significantly reduced over the last

few years, they have limited use without labor intensive data tagging.

Goals• Improve economic value for nuclear facilities• Open method for import into analysis tools

LiDAR Project Overview

light detection and ranging (LiDAR)

Basic• Virtual walkdown• Measurement tools

Tagged Model• Component lookup• Maintain piping and

instrumentation diagrams (P&IDs)

• Spatial relationships• Data export

Use Cases

Industry Partner – Environmental Intellect (Ei)• Web based• Photo or point cloud• Markers/Tags• P&ID features• Group or Team layers• Measurement tools• Secure Data

3D Visualization

Input Nuclear Data

• List components for current zone.• Four click process

Initial Simplified Tagging

LiDAR scan• Switchgear room• Pump room

Database import• PDMS• FRANX

Tagging process

Est. cost $50–$200K

Industry Testing

Not actual industry scan

Computer Vision• Identify label text• Sort components

Goal• Tagging reduced to < 10 sec avg.

Assisted Tagging (2022)

Model Import Example (2022)

• Use API for data retrieval • Auto generate room boundaries• Import components into FRI3D
