geometrierfassung

Geometrierfassung refers to the process of acquiring and representing the geometric properties of an object or environment. This can encompass a wide range of techniques and applications, from simple measurements to complex 3D modeling. The primary goal is to capture the shape, size, and spatial relationships of physical entities in a digital format.

Common methods for geometrierfassung include traditional surveying techniques, which use instruments like theodolites and total stations to measure angles and distances. More modern approaches utilize laser scanning technologies, such as LiDAR (Light Detection and Ranging), which emit laser pulses and measure the time it takes for them to return, creating dense point clouds representing the scanned surface. Photogrammetry is another prevalent method, where multiple overlapping photographs are taken from different viewpoints, and software is used to reconstruct a 3D model based on the parallax information.

The output of geometrierfassung can vary depending on the method and intended use. This can range from 2D drawings and plans to detailed 3D point clouds, meshes, or parametric CAD models. These digital representations find applications in diverse fields, including architecture, engineering, construction, manufacturing, cultural heritage preservation, virtual reality, and autonomous systems. The accuracy and level of detail required often dictate the choice of technology and methodology employed.
