3D Laser Scanning

Summary

3D Laser Scanning - also known as 3D Scanning, is a non-destructive, non-contact method of capturing floor surface regularity using laser imaging technology.

Technical Information

Laser imaging technology uses Lidar (light detection and ranging) to capture floor surface regularity against current floor specifications, according to the usage of the facility.

How Do 3D Laser Scanners Work?

Pulsed light waves are emitted from the scanner which bounce off the floor and are directed back to the scanning sensor. The time taken for a pulse of light to return to the sensor is used to calculate the distance it has travelled. The distance and direction are recorded as a point of data. The process is carried out millions of times a second and the points from the shapes and dimensions of the floor scanned are collated and plotted in a 3D digital space.

3D Scanning Advantages and Limitations

Advantages

State-of-the-art surveying technology
Applications for quick on-site analysis
High density of readings
Easy to view and share

Limitations

Line of sight access is necessary
Dirt on the floor can cause error readings
High gloss surfaces create problems for the lasers
Processing of the point cloud data requires skilled technicians to interpret the results
Risk of false positives and false negative readings
Accuracies and uncertainties need to be investigated and accounted for. These can make up a large percentage of the property limits that compliance is being checked against.
