3D Laser Scanning
3D laser scanning is a great way to create as-builts of highly ornate buildings, the interior of industrial facilities that have complex systems routed throughout them, art models, crime scenes and the list of uses goes on and on. 3D laser scanning, or high-definition surveying as it is synonymously known as, could be useful to archaeologists, architects, contractors, engineers (civil, structural, etc.), forensic investigators and plant designers.
The Equipment
There are a number of different high-definition surveying (HDS) systems on the market today. An excerpt of the product specifications of one such 3D laser scanner is as follows:
| Leica HDS6200 | |
|---|---|
| Instrument type | Compact, phase-based, dual-axis sensing, ultra high-speed laser scanner, with survey-grade accuracy and full field-of-view |
| Operating temp. | -10° C to +45° C |
| Lighting | Fully operational between bright sunlight and complete darkness |
| Humidity | Non-condensing |
| Reflectivity | No retro-reflectors |
| Accuracy of single measurement | 5mm, 0.4m to 25m range (At 127.000 pts/sec scan rate, one sigma) |
| Range | 79m ambiguity interval |
The Procedure
The procedure to create drawings from a 3D laser scan is a two-step process that consists of field work first, and CAD work second.
