Laser Scanning: FAQs
Laser scanning is a method of Reality Capture using laser beams to efficiently digitize 3-dimensional data on the surface of an object or environment without touching what is being measured, much like a 360-degree photo, but with an accurate position on every individual pixel.
What Is Laser Scanning?
Laser scanning is a method of Reality Capture using laser beams (LiDAR technology) to efficiently digitize 3-dimensional data on the surface of an object or environment without touching what is being measured – much like a 360-degree photo, but with an accurate position (x, y, z) on every individual pixel. Scanning produces millions of measurement points in a scene with intricate geometric detail creating a form of raw data called a “point cloud”.
What is Laser Scanning Used for?
Common applications of laser scanning include:
- Renovation/Refurbishment current conditions
- Heritage documentation for historical preservation
- Construction projects:
- quality assurance checks (change and clash detection with BIMs)
- capture progress milestones
- perform completed work assessments
- as-builts for facilities management
- Infrastructure – roads, rail, bridges, and tunnels
- Plant & facility management – oil, gas, refineries, and pipelines
- Topographical surveys
- Calculating volumes, clearances, and deviation analysis
- Floor slab mapping and flatness reporting
- Accident scene reconstruction
- Hazardous or hard-to-reach surveys
- Prefabrication and reverse engineering
Why should I consider Laser Scanning? (aka Benefits of…)
A single laser scanner can capture millions of 3D data points per second, providing intricate detail of every aspect of your project in a fraction of the time taken by conventional methods.
Remove uncertainty and greatly reduce project liability with comprehensive spatial and visual accuracies previously unachievable.
Incorporating a laser scan into the design of your project assures more efficient and accurate communication promoting faster decision making and enlightened team collaboration.
Never miss a measurement again. A 3D laser scan will capture complete detail reducing or even eliminating the need to return to the project site to answer unanticipated questions.
Eliminate or minimize operational shut-down times and client inconvenience with rapid data acquisition.
Scanning is a touchless technology normally completed safely from the ground without the need for harnesses, lifts or cranes. Measurements can be obtained remotely in hard to reach or hazardous locations keeping workers out of harm’s way.
