What is Laser Scanning?
It is a measurement technology that uses laser beams to create three-dimensional digital copies of physical objects or spaces.
Overview
Laser scanning sends millions of laser beams onto the surface of objects, calculates their reflection times, and thereby generates three-dimensional point clouds with millimeter precision. The data obtained in this way forms the basis for producing digital twins in fields such as architecture, engineering, and game development. It can be thought of as a digital and much faster version of measurements made with a traditional ruler or tape measure.
How it works
The device fires thousands of laser beams around per second and finds the distance by measuring the return time of each beam. The millions of collected points are combined in a computer environment to obtain a three-dimensional model of the object that looks just like the real thing.
Where it is used
It is used in the digital preservation of historical artifacts, checking the current status of structures in the construction industry, and enabling robotic systems to perceive their surroundings.
Commonly confused with
It is different from taking a photograph because it does not just record color and image, but also mathematically measures the depth and distance of the object.
Questions and answers
What is a point cloud obtained by laser scanning?
It is a three-dimensional draft formed by bringing together millions of coordinate points on the surface of the scanned object.
In which fields is it most needed?
It is frequently used in architectural restoration, autonomous vehicle development, and industrial design projects.
