Understanding Point Clouds Laser Scanning
What is Point Cloud Data?
Point Cloud Data is a digital representation of a physical space or object. It is a collection of millions of data points in a three-dimensional coordinate system. These points are generated using a 3D laser scanner, capturing the exact spatial position of objects within the surveyed area. This data forms the basis for creating accurate 2D and 3D models of existing structures.
Principles of Laser Scanning Technology
Laser Scanning Technology, specifically Terrestrial Laser Scanning (TLS), is a revolutionary method of data acquisition. It utilizes a laser rangefinder to rapidly measure distances to objects, creating a dense cloud of points. This technology is capable of performing an astounding number of scans per second, making traditional methods seem glacial in comparison. The precision achieved is within an impressive range of 1-2 mm, virtually eliminating the possibility of error.
