Most asked questions about 3D laser scanning
Are you in the process of conducting research about 3D laser scanning technology? 3D laser scanning technology can be used for a whole host of applications and there is a lot to learn when you are considering this technology for your own project. At Hive Virtual Plant, we are experts in 3D laser scanning and everything that surrounds it. In this article, we provide some information about some most asked questions about 3D laser scanning for your research.
What is a Point Cloud?
As the name suggests, a point cloud is a series of points in a digital 3D space. Similar to the connect-the-dot books of our childhood, a Point Cloud is a 3D series of points depicting something that has been digitally scanned in some way, minus the lines to make the picture.
What can be scanned with a laser scanner?
Almost anything can be scanned. The only limitations are highly reflective items like mirrors and highly polished surfaces, transparent items like glass and liquids, and items that refract and reflect light, like number plates and hi-vis clothing reflective panels. 3D laser scanning can be used for many different applications.
Can you scan big areas and multiple levels of buildings?
Yes, it is possible to scan large areas and even multiple levels provided there is a way to traverse around the site, doing scans in locations with common lines of sight. To be able to go up levels inside buildings, it is necessary to have at least one stairwell to traverse between levels. It is often preferred to have at least 2 stairways, one on either side of the building ideally, or a line of sight to a common point through an open door or window from each level.
How does it work?
The 3D Laser Scanner sends out a laser beam which then reflects off objects and returns to the scanner’s sensor. The scanner then uses its onboard computer to calculate where in space the return came from and creates an X, Y, Z coordinate relative to the centre of the scanner for each return.
These are just a few of the popular questions that are asked about 3D laser scanning. To learn more about 3D laser scanning technology, we encourage you to get in touch with our Hive Virtual Plant team today.
