What is a LIDAR (3D) Scanner?
A LIDAR 3D scanner is a rotating laser that defines all object in its field of vision with millimeter accuracy.
Using an infrared light to determine the distance between itself and an object, the scanner monitors how long it takes the lasers’ pulse to bounce back. Based on the differences in laser return times, and by varying laser wavelengths, the 3D scanner produces a digital 3D image that looks very similar to a photo, but data rich. This resulting 3D representation is called a point cloud. LIDAR 3D scanners are commonly used to collect as-built conditions in construction, facilities, and manufacturing to name a few.
- LIDAR 3D scanners produce a true to scale digital representation of a built space.
- LIDAR 3D scanners bring the field to the office, allowing you to identify and solve existing condition issues before ever breaking ground on a project.
- LIDAR 3D scanners can quickly compare existing conditions against design drawings or a 3D model in-situ.
- LIDAR 3D scanners are non-contact measurement tools, reducing the need to put contractors in high-risk areas/situations.
- LIDAR 3D scans are the first step in any pre-construction simulation.
- Capture as-built conditions, model existing spaces for prefabrication and QA/QC installs.
- Capture images and point clouds in relation to survey control for documentation and/or digital twinning.
- Determine FF/FL based on the ASTM Standard.
- Calculate volumes of dirt or shotcrete and concrete.
- Accurately verify location and rotation of anchor bolts.
Trimble Field Technology
Imagine starting a refit and renovation project with precise and accurate details of the as-built conditions already in hand? With Trimble’s 3D laser scanners, having no original drawings is not a problem. Knowing exactly what to expect before work starts, reduces design errors and costly field rework. You can also reap the rewards of having accurate as-built conditions for new construction projects and QA/QC it. This information is invaluable to owners and allows for reducing costs on future work. Scan the physical environment and capture accurate measurements for use in your design and detailing process.
The registered point cloud data is invaluable in overcoming the usual challenges posed by refit and renovation projects. The built-in camera means the point cloud will be in full, photo-realistic, color. Trimble’s 3D Laser Scanners are the ultimate answer for contractors looking to tackle complex retrofit projects while meeting tight deadlines and maintaining profitability.
