Scan Process

• Capture Process

  Engineer carries the hand held LITHIC scanner while he walks across the project site

• Scanning Duration

  Typically 50K sqft is scanned within a duration of 30 minutes

• Scan Data

  RGB, Thermal, IMU, LiDAR and Multi-Spectral Data is dumped in the integrated SSD of LITHIC

• Scan Period

  These scans are conducted on periodic intervals to update the 3D model to reflect the real time work status at site

LITHIC

• LITHIC is the acronym for Lidar-Thermal-IMU-Camera. It Includes a 360 LiDAR, IMU sensors, RGB camera, Thermal Camera and a Multi Spectral Camera

The Measurable 3D Model!

• 3D Mesh

  The 3D as-built measurable engineering model is freely navigable, downloadable and viewable on Observance

• 2D Plan

  A cleaned, vectorized and scaled as-built 2D floorplan with option to export to DXF (AutoCAD)

• Measurements

  Accurate Linear, Angular, Area, Volume Measurements enabled on the outputs with imperial/metric system

• Accuracy

  All measurable outputs on Observance have an accuracy of 99.2%

Side-By-Side View

• 3D Scan vs Camera Video

  3D textured model can be viewed side-by-side with camera video and thermal video synced to the nearest best camera angle corresponding to the 3D viewpoint

• 3D Scan vs BIM Model

  Scan Model can be compared with the BIM to track differences with color coded textures representing distance between them, search range for which can be configured from 0-1 m

• RGB vs Thermal

  Compare RGB Camera and Thermal Camera videos side-by-side with synchronization

Slider View

• Old Scan vs New Scan

  Any two models or video of two different scan dates scan be loaded and "slided" across to see differences between them. All 3D View features like Section Plane, Measurement and Annotations work seamlessly with Slider View

• "Peel Off"

  View perfectly synced models and videos to reveal elements at different timelines but at the same location

• Scan History

  See historical time-lapse changes between the scans over a period of time with precise alignment

Thermal Analytics

• Processing

  Thermal Camera data is synced with the RGB Camera to the nearest milisecond to create a thermal texture to the model, which provides precise thermal readings in 3D

• Moisture Seepage

  Thermal texture color sensitivity range can be remapped to desired range that reveals various moisture patterns which enables early detection of leaks and moisture seepage

• Leak Profiling

  The data can be utilized to analyze MEP installations for integrity check and automated leak profiling

Defect Analytics & Punch Lists

• Snags AI

  Common visible snags like cracks, honeycombs, chipped surfaces, uneven surfaces, cement slurry and moisture seepage automatically recognised and notified as Punch Lists

• Annotated in 3D

  All the Snag Items are automatically mapped onto the 3D Models and converted to an annotation with Camera Images indicating the item

• AI Training

  More than 400,000 annotated images are currently used to train the AI model on 30+ defect types

Task Manager

• Annotations to Task

  3D Annotations, Snag items and PPE Violations can be assigned to someone as a task with start date, due date and task status

• Task Features

  Tasks can be assigned to multiple individuals, create sub tasks, reassign task to another individual. All of which can be visualized with a comprehensive gantt chart

• Access Controls

  Tasks are hierarchical, requiring the completion and relevant commentary of subtasks for the parent task's completion. Every task includes automatic audit trails for change documentation.

Health&Safety Analytics

• Facial Recognition

  FR is run on entry and exit cameras and live notification with images of Recognized, Unrecognised and PPE Incidents are reported in real-time to Observance Dashboard

• PPE Detection

  AI trained model on Helmet, Vest and Boots to detect PPE Violations for people working on site

• AI Reports

  Autogenerated reports for Attendance, PPE Violations, Blacklisted people and Unknown person for a given date and time range
