We offer 3D Laser Scanning services for a great variety of applications, ranging anywhere from creating as-built data for industrial plants, to preserving some of worlds most unique historical sites.
What is Laser Scanning?
3D Laser Scanners use a (low power) laser to obtain millions of three-dimensional measurements very rapidly.These measurements provide point clouds from which surfaces can be modeled. Point cloud data collected from the scan can be viewed through various softwares programs. Measurements needed for the particular project can then be extracted and used to make accurate calculations.
What is Laser Scanning used for?
We have developed a sophisticated scanning process which gives our clients a very accurate point cloud. The point cloud may be used for many applications, including modeling, kinematic simulations, engineering design, construction as-built documentation, asset management, and historical preservation.
How we use Laser Scanning?
Our laser scanning workflow combines conventional horizontal and vertical survey control with laser scanning on most jobs. This ensures that the scan data is correctly located and oriented in a standard real-world coordinate system, which is critical for many applications, and always desirable for greatest utilization of the scan database.
What are the Advantages?
- Speed – The fastest scanners record up to one million data points per second. “Virtual Surveying” from the resulting point cloud is often much faster and more economical than conventional surveying “on the ground.”
- Extensiveness – Three-dimensional coordinates are captured from all surfaces within the scanner’s range and field of view at a high level of detail, including poorly illuminated areas; scanners can operate in total darkness.
- Accuracy – Because typically millions of points are collected, statistical “best fit” positions and dimensions can be computed to locate features and determine feature sizes and shapes with very high accuracy.
- Non-Intrusiveness – Laser scanners are essentially active remote sensing devices that can “see” up to 300 yards. Work interruptions or facility downtime to accommodate surveying is virtually eliminated.
- Safety – Entering roadways, climbing scaffolds, and dodging heavy equipment is largely eliminated. Scanner positions are typically located in non-hazardous area.
- Permanence – Scan data and derivative models can be re-used for later unanticipated inquiries, or even totally new projects. Return trips to the site are practically eliminated.
- Versatility – Laser scanning can support land surveying, 3-D modeling, Facility Information Management, Building Information Modeling (BIM), forensics, and much more.
