3D laser scanning is a technology that captures the physical shape of objects and environments by using laser beams. A laser scanner emits thousands of laser pulses per second, measuring the distance to surfaces and creating a detailed 3D representation, known as a point cloud. This data can be used in various fields, including architecture, engineering, and construction. The resulting 3D models can help professionals visualize and analyze structures more effectively. 3D laser scanning is particularly useful for documenting historical sites, creating digital twins of buildings, and improving design accuracy in manufacturing and construction projects.
