In recent years, 3D laser scanning has changed the way land and buildings are measured. This cutting-edge technology uses 3D laser scanners to collect accurate spatial data, which is then used to create models of physical environments.
This guide will outline how 3D laser scanning technology works, how data is delivered to clients as well as the benefits of using a 3D scanning survey for your project.
How does a 3D laser scanning survey work?
A 3D laser scanner sends out laser beams in different directions and measures distances to objects by calculating the time it takes for emitted laser pulses to bounce back.
These scanners are equipped with high-resolution cameras to capture colour and texture details, By using multiple scans from different positions, surveyors can create a comprehensive 3D point cloud to represent the scanned area.
The data capturing process
During a 3D laser scanning survey, scanners are strategically placed at different vantage points to cover the entirety of the area or building being surveyed.
The scanner collects millions of data points, creating a detailed point cloud model, which is then used to accurately depict the intricate details of the scanned space, including the textures, dimensions and minute irregularities.
How information is delivered to clients
Once the scanning process is complete, special software is used to handle the collected data. The 3D point cloud model can be sent in various forms, such as Computer Aided Design (CAD) or Building Information Modelling (BIM) files.
The end product can also be published in Trimble Realworks Viewer format. With a free plug-in, you can view, change, zoom , measure, and make notes on point cloud image data.
It’s quick and simple to use, and it provides coordinates and measured lengths Scans can be provided in several formats, like 2D and 3D AutoCAD drawings, paint clouds and rectified images.
Benefits of 3D laser scanning surveys
There are several benefits of 3D laser scanning surveys:
- Accuracy and precision: 3D laser scanning gives very exact measurements, reducing potential mistakes during the building and design process.
- Timesaving: traditional measuring methods often take a long time, whereas 3D laser scanning speeds up the data collection process, saving time and resources.
- Comprehensive data: laser-scanned models hold a lot of useful information for building engineering and architecture.
- Reduced costs: 3D laser scanning streamlines the survey process and ensures crucial details are included, decreasing project costs. Non-contact data capture: these surveys are non-contact and non-invasive, making them the best survey option for sensitive environments, such as heritage sites.
