3D Laser Scanning

3D Laser Scanning Technology. A common misconception about 3D laser scanning I think you’ll agree with me when I say 3D laser scanning, all that comes to mind is barcode scanning or x-ray body scan at the airport. The best part is when people go as far as to say that laser scanning is radioactive and it is best to stay a mile away from the scanner.I agree it does look like alien technology, but in fact the laser scanner is a combination of electronics and precision optics plus and years of experience all built into a robust, portable unit. 3D laser scanning creates a digital representation of a physical object in the form of a point cloud which can later be converted into a 3D model.   What is 3D laser scanning? In simple terms, 3D laser scanning is a non-invasive and non-destructive method to collect measurement data. It captures the shape of physical objects, buildings, infrastructure, etc. using pulses of laser light. As the scanning is in progress, it stores the measured points in files called point clouds. The laser light is able to capture any free-form shape within its range, to a surprising level of fine detail.

They can also be used to audit material inventories. How is this useful for auditing? Let me explain in an example. Dirt and loose materials are hard to measure due to their free-form shape. In the past, measurements were usually done with estimations using height, width and length. Using 3D laser scanning however, we are able to accurately capture the shape of the dirt pile in a 3D model and calculate the volume to a more precise degree. The accuracy of this process makes it suitable for volume calculation of stockpile inventory and auditing purposes. Dirt pile in 3D. Why do 3D laser scanning? Here’s the deal: Low costLow time of data acquisition.Saves time and money.Full and accurate 3D representation of the objects which can be used for measurement.Point clouds that can be used for CAD modelling.2D plans and 3D models that are compatible with standard CAD software such as AutoCAD.Easy 2D and 3D documentation for engineers, B.I.M coordinators and architects.Scanning allows reconstruction of complex structural elements.Easy conversion of laser scanning into ORTHOPHOTOS.Volume calculation for materials that do not have a regular geometric shape.Point clouds can be converted into the appropriate format to be used for inspection or reverse engineering.

Another One Bites The Dust

0000Nothing lasts forever, and unfortunately for our power generation customer near Dallas, Texas, that includes wind turbines. When a wind turbine has a catastrophic event, it can raise the question: was the tower damaged? Sometimes tower damage is obvious, but other times there can be very sutle dents, twists or bends that are not obvious to the naked eye. This is where 3D laser scanning comes in. From a safe distance, the 3D scanner can capture the geometry of the tower into an accurate …

Create As-Built Drawings of Power Plant

0000Our client needed as-built drawings of the exhaust section portion of a power plant using 3D scanning in Alexandria, LA. The CAD model was needed to plan for scrubber installation at this plant. We approached the problem like any power plant, deploying our 3D scanners to capture an accurate point cloud. The scanning took 3 days. We then used the point cloud as a reference to extract a 3D CAD model. This was done in two phases; an initial phase where we captured major duct, structures and …
