3D Laser Scanning - also known as 3D Scanning, is a non-destructive, non-contact method of capturing floor surface regularity using laser imaging technology.
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
- State-of-the-art surveying technology
- Applications for quick on-site analysis
- High density of readings
- Easy to view and share
- 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.
