The Cutting Edge of Capture: An Insight into Laser 3D Scanning

Laser 3D scanning is a transformative technology that captures the physical characteristics of objects or environments and converts them into detailed digital 3D models. By utilizing laser beams to measure distances with remarkable precision, this process creates a comprehensive representation of the scanned subject. One notable advancement in this field is the Eagle LiDAR Scanner, which integrates cutting-edge features to enhance the laser scanning experience. In this blog, we will delve deeper into the mechanics of laser 3D scanning, its diverse applications, its advantages, and how the Eagle LiDAR Scanner stands out.

 

How Does Laser 3D Scanning Work?

"Within the field of 3D object scanning, laser scanning (also known as lidar) combines controlled steering of laser beams with a laser rangefinder. By taking a distance measurement in every direction the scanner rapidly captures the surface shape of objects, buildings, and landscapes. Construction of a full 3D model involves combining multiple surface models obtained from different viewing angles, or the admixing of other known constraints. Small objects can be placed on a revolving pedestal, in a technique akin to photogrammetry." -- From Wikipedia
