For smaller to medium sized projects soley using terrestrial 3D laser scanners can often fulfill the accuracy requirements of most projects. However, for larger terrestrial 3D scan projects or projects that require the greatest accuracy possible we offer the additional use of a total station and targets to apply survey control to the data obtained from the terrestrial 3D laser scanning. Using a total station to establish survey control points allows us to much more accurately register large scan data by taking advantage of the considerably more accurate angular and range accuracy of a total station compared to a terrestrial 3D laser scanner. In turn, using a total station with terrestrial 3D laser scanners allows us to correct for any drift in measurement data that may occur in large terrestrial 3D laser scanning projects.

While terrestrial 3D laser scanners can fulfill the accuracy requirements of most projects some applications require an even greater level of accuracy that terrestrial 3D laser scanners cannot achieve. In such cases, we offer the use of handheld 3D laser scanners, which have an accuracy of 0.02 mm, for small to medium sized objects and the use of coordinate measuring machines (CMM) and total stations for larger projects.

The two main types of CMMs we employ are the Faro arm and Faro laser tracker CMM which both have micrometer accuracy. Faro Arms is used to collect probing and/or scanning data of smaller high-precision objects such as molds for applications such as inspection and reverse engineering. Faro Laser Trackers are used for larger objects to obtain point-based measurements for applications such as roller mill alignment, turbine alignment, inspection of larger machinery, reverse engineering, and dimensional measurement for retrofit. Using a combination of terrestrial 3D laser scanners, total stations, handheld 3D laser scanners, arms, and laser trackers allows us to obtain the most accurate and comprehensive measurement possible tailored to the requirements of a project.
