Metrology is the science of measurement. Measurements is an important part of human history particularly for science and trade. Measurements can be taken in many ways for different purposes and applications. One such way is 3D scanning which is done by using HDR Laser Scanners for large and long-range applications, ultra-precise handheld 3D Scanners for short-range applications, and Aerial Drones and high-resolution cameras for applications in the heritage, agriculture, and mining industries. Data from different 3D scanning equipment is used separately or combined to get measurements for complex models and geometries that would otherwise not be possible.
