VERIFY 3D GLOSSARY
A measurement that includes three values, one each for the X, Y, and Z directions. The values are the distances from an arbitrary 0,0,0 point.
A surveying instrument that emits pulses of laser light and calculates distances based on differences between the emitted pulse and the light that was reflected back from some object.
The set of 3D measurements with X, Y, Z, coordinates collected by a laser scanner. When the measurement points are displayed on a computer screen, the image resembles a cloud or a late 19th. Century Pointillist painting.
Combining multiple scan positions into a single conglomerate point cloud. Scans are mathematically aligned using millions of overlapping points between stations. Methods include scan-to-scan and scan to target registration. Targets may be placed on survey control points allowing registration to global or site survey coordinates.
