3D laser scanning is a great way to create as-builts of highly ornate building facades, the interior of industrial facilities that have complex piping, structural, and mechanical systems, hard to access signage, and the list of uses goes on and on. Therefore 3D laser scanning, or high-definition surveying (HDS) as it is synonymously known, could be useful to architects, contractors, engineers (e.g. civil, structural, etc.), plant designers, and others too.
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:
|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|
|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 to create drawings from a 3D laser scan is a three step process that consists of scanning first, scan data registration second, and lastly data modeling/processing. Below is an introductory video on HDS.
I've been a part of putting together a number of 3D laser scanning projects in New York City. Below are images of just a couple of the projects.
