LiDAR & Reality Capture

LiDAR (Light Detection and Ranging) scanning captures millimetre-accurate 3D point clouds of any built environment. Applications include as-built documentation, change detection during construction, volumetric analysis for mining, BIM model creation, heritage preservation, and digital twin development.

Oculus uses Trimble X7, X9 and X12 terrestrial scanners achieving point accuracy of plus or minus 1.5mm at 50 metres. NavVis MLX mobile mapping achieves plus or minus 5mm for rapid indoor/outdoor capture. Accuracy specifications are confirmed for each project based on the survey control network.

Deliverables include registered point cloud data in industry-standard formats (E57, LAS, RCP), 2D plans and sections, 3D mesh models, and web-based or desktop viewer access for measurement and collaboration agreed in the scope. BIM models (Revit, IFC) and volumetric calculations are available as add-ons.

Scan time depends on the site size and required detail. A single room takes 15 to 30 minutes with the NavVis MLX. A full building floor takes 2 to 4 hours with a Trimble X7. Large industrial sites or mine pits may take multiple days. Registration and processing typically adds 2 to 5 business days.

Yes. Oculus can overlay continuous monitoring sensor data onto the 3D point cloud model, creating a spatially-referenced digital twin where movement, vibration, and environmental data are visualised in the context of the physical asset. This is particularly useful for long-term asset management.
