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. Oklahoma State Capitol State Capitol in Point Clouds. 3D laser scanning is an ideal alternative for capturing the exact shape and size of an object as compared to the traditional method of hand measurements and CAD drawing. 3D laser scanning is able to improve the engineering and design process by speeding up measurement tasks and reducing or eliminating data collection errors. 3D laser scanners are commonly used for on-site surveying of topography, internal and external building structure, piping, conduit and equipment. 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. Inspection Scan Rev. Engineering Once 3D laser scanning produces 3D model, what can I do with a 3D model I would assume that…

Scanning UTMB League City, Texas

Scanning UTMB League City Campus Hospital A year old UTMB League City Campus Hospital was up again for infrastructure advancement to sustain the growing number of patients and visitors. A new block was already on its way and our client was short listed to build the covered parking lot for the hospital and a bridge leading from the parking lot to the main block. UTMB Arrival3D was called in to scan the perimeter around the campus to provide our client the current view and newer development for the hospital. The client was going to use the scan as part of their presentation for visual references and future proposed construction for the parking lot. The area to scan. Area scanned includes an open area with field, perimeter around the main building and the roof of the hospital. Each scan took about 5 minutes. 2 full working days were required to cover the 3 areas mentioned above. Point cloud of the Campus Then entire project was registered and aligned using Autodesk Recap. The file was unified to 50mm point spacing to speed up the delivery process to the client as the client required it A.S.A.P. The complete file (30 gb) was delivered a few days later for references with greater detail and point density.

Porsche Rear End Scanning: Corona, CA

PerformancE automotive scanningMore and more, the automotive performance aftermarket industry is utilizing 3D technology to deliver extremely precise and innovative designs. We recently had the pleasure of scanning a Porsche GT3RS hatch and rear end. Our client was looking to create custom fabricated parts for the rear end of this extremely sleek and powerful vehicle.Equipped with our new EviXscan HD Optima structured light scanner, we simply needed to apply targets to the rear end of the GT3RS and apply some light talcum powder spray for preparation. After that, it was just a matter of positioning the scanner across various scanning points along the rear end. In no time, we had a completed and aligned model of the rear end of the GT3RS. The versatility of the HD Optima allowed us to capture the vehicle’s sleek geometry on-location within a matter of hours3D Scanning: The Design Process SolutionWith the completed and precise model of the rear end, our client is able to now design their own custom fabricated parts for manufacturing. It really goes to show how fast the industry is changing in terms of design, manufacturing, and inspection. With more and more aftermarket and racing shops looking to gain an edge, 3D scanning technologies are truly the way to go. For more information regarding our 3D scanning services, click here.

Trolley Rail Spacing and Elevation Measurement Using 3D Scanning Near Dallas

0000Our customer needed to replace a section of trolley rails on the Granbury dam southwest of Dallas. They needed to ensure that the new replacement rail was within spec (distance between the rails and flatness). They had used Arrival 3D in the past to scan an interior wall within another dam, so they decided to utilize our 3D scanning services for this project as well. Getting there is half the battle sometimes, as the scanning itself was rather quick. With a handful of scans, we captured the …

3D Scanning Golf Green in Dallas, TX

0000Arrival 3D performed 3D scanning for our esteemed customer in Dallas Texas. The customer needed to map the slope of the green. 3D scanning golf courses is a great way to capture and preserve the shape of the course. In the event that the course was destroyed by a natural disaster or other cause, the course could be rebuilt with precision using the 3D mapping information from the scan. Here is an example of a slope map applied to a golf green. Slope maps can very nicely depict the subtle …
