The most widely used scanning technology used by our team and the industry is 3D laser scanning. A laser line emitted is being watched by a camera at an angle to generate 3D data. Usually a device tracks the location of the 3D Laser Scanner in space and can even be operated within the processing software. Most of the system is self-adjusting so it can be operated with very little training.
3D object laser scanning speeds up the design process while decreasing errors. This not only saves time and money, but makes it superior to traditional data collection techniques. X and Y coordinates are measured by the deflection of a laser beam at one level. And the Z axis coordinate is measured by a specific optic that is able to move the laser's focal point in the depth-direction. They are ideal for reverse engineering and rapid prototyping.
A relativiely new application of laser scanning is mobile mapping which is a process of collecting geospatial data from a mobile vehicle. The most familiar output is the street view as seen on Google maps. The outputs of mobile mapping include GIS data, digital maps, and georeferenced images and video. Leica Geosystems mobile mapping solution uses a laser scanner (or several scanners) in combination with GNSS receivers, Inertial Measurement Unit (IMU) and a Distance Measurement Instrument (DMI) on a mobile platform (vehicle) to acquire accurate and precise spatial data.
3D laser scanning can be used in land surveying. Surveyors make precise measurements to determine property boundaries. With the advancement of laser scan equipment it is possible to do it faster and more accurately. The equipment and laser scanning software provides data relevant to the shape and contour of the Earth’s surface for engineering, mapmaking, and construction projects to determine the three-dimensional position of points, distances and angles between them, commonly practiced by surveyors.
For as-built, topographic, detail, and engineering surveys, Leica High-Definition Surveying (HDS) systems are the way to go. Leica Geosystems HDS Cyclone software modules provide point cloud users with a wide set of work process options for 3D laser scanning involving engineering, surveying, construction and related applications
Able to complete 3D scans of any large space: be it a room, landscape or entire building, our long-range scanning technologies can obtain highly accurate, extremely detailed 3D scan data.
Exact Metrology can recommend the best laser scanner equipmend for the job. For example, the Leica ScanStation P20 has excellent accuracy-at-range with fewer setups.

Ancient objects and artifacts are not only irreplaceable but often extremely fragile. Romer has a great case study of their articulated arm laser 3D scanner in use with an ancient object. When the Nelson-Atkins Museum of Art in Kansas City, MO opened its new Egyptian galleries this year, the world got its first glimpse of an elaborate and complete funerary assemblage from the tomb of a 2,300-year-old noblewoman named Meret-it-es.
Museums use 3D Laser Scanners on sculptures to create replicas as well for structural data. The information gathered can be used to preserve and study sculpture.
