Laser scanning is one of the latest technology, which had been used in surveying since the 1990s. It soon became a standard in surveying with its capability to make the most accurate measurements in complicated environments. The accuracy and quality of laser surveying had also increased day by day, and now 3D laser scanning is the latest technology, which is in general practice, offering optimum quality output.
Now, 3D laser is precisely used as the best solution in measuring the as-built conditions outside and inside buildings. The latest 3D laser scanning can collect the survey data points at the fastest rate of 50000 points / second. The same method can be now used to create 2D drawings and 3D computer models with the help of CAD software and further used to prepare the final survey documents.
High definition 3D laser scanning
This technology is called in various names as 3D laser imaging, 3D laser surveying, 3D laser scanning, as well as high-definition (HD) surveying. This mode of surveying is expected to become a norm in the future when it comes to land surveying. There are many benefits of high definition surveying, which we will discuss as below.
High-definition surveying are the best solution for the measurement professionals as land surveyors in order to gather the most accurate spatial information. Professionals who use 3D laser scanning methods now are the;
q Civil engineers
q Plant designers
q CAD professionals
q Civil work contractors
q Forensic investigators
q Archaeologists etc.
Benefits of HD laser scanning
The primary advantage of using 3D laser scanning is he cost benefit when compared to the conventional surveying methods. Significant cost savings offered by a typical HDS system is in many ways as;
q It can lower the cost in typical topographic and as-built surveys.
q Cost involved in the need for return visits can be significantly reduced or completely eradicated with this mode of surveying.
q High definition 3D laser scanning can offer the m most accurate and complete as-builts for the retrofit design projects.
q There is only lesser or no need for construction reworks due to any interference at the 3D laser scanned sites.
q This can also help reduce the facility downtime as this mode of scanning is must faster and unobtrusive in terms of scene capture.
q It can also help minimise field fit-up and field fabrication needs.
Other value additions comes packed with high definition 3D laser scanning also include.
q Better / faster results
q Shorter time and reduced project cycle timings
q More complete output with less ambiguity
q An eye on detail made enabled.
q Safer and comfortable data capture
q Unobtrusive capturing of data.
q Much efficient project management as point clouds can be easily and conveniently reviewed by others.
High definition 3D laser canning is also now used in cross-functional settings like surveying of the hard-to-reach terrain, assess construction progress at work sites, capturing digital 3D photos, video surveys etc. There are plenty of providers offering this service and when it comes to choosing one the primary aspects one should check is the experience and expertise level of the provider as well as the quality and relevance of the 3D laser scanning equipment they use.
