If your company or organization has laser scanning needs, you have two basic options: you can purchase your own scanning equipment and do your own scanning, or you can outsource your scanning needs to a 3D scan service-also referred to as a laser surveying service. For most entities that have scanning needs, whether to buy scanning equipment or hire a 3D scan service is based on two factors: the cost of the equipment and the frequency of the scanning need. For entities that need scanning on a daily basis, purchasing their own equipment is usually the best option. But for entities that require only occasional scanning, the high price of top grade scanning equipment-the cost of a tripod scanner can easily exceed $100,000-usually makes outsourcing the better option. If you choose to outsource, the first step toward meeting your needs is understanding the range of services that 3D laser surveying services providers offer. Below, we list a range of services that are common to most full scale surveying providers.official site is an excellent resource for this.
Architectural surveys are useful for a variety of reasons, including: detecting areas of roofing that are in need of repair; developing enhanced building security measures; and developing ideas for interior decoration modeling that make sense to a building’s exact proportions. Architectural surveying is also used to scan heritage architecture so that it can be restored to its precise original form in the event of gradual or sudden damage.
Construction surveying and architectural surveying often go hand in hand, with the former being used for such purposes as: linkage of information between architects and engineers, grading volume calculations and verifications, verification of adherence to engineering specification, topographical verification after land has been cleared, building height measurements to avoid crane collision; and soil erosion measurement on and and around a building site.
Since its introduction in 1998, laser scanning has become heavily associated with engineering and reverse engineering through the following applications: quality control inspections, reproduction of heritage parts, BIM modeling, 3D topographical site scanning, early measurement and verification of foundation structure, provision of real time GPS, and clash control for piping.
One of the newer uses of laser surveying is historical surveying, which pertains to gathering the interior and/or exterior data from sculptures and other objects, buildings and historical spaces, and environments for restoration purposes in the event that they becomes damaged, as well as for producing smaller models of heritage objects, as the Eiffel Tower is a perfect example. A recent use of surveying for restoration purposes can be seen in the May 2010 scanning of the Mount Rushmore monument.
-Crime and Accident Scene Surveying
Another newer use of laser surveying is crime and accident scene surveying, where investigators use a laser scanner to gather the physical data from the setting where a crime or accident occurred. With the data collected, it can then be used to ascertain such things as bullet trajectory and accident timing, and can also be used to create 3D animations of how a crime or accident transpired based on physical data.
