3D Laser Scanners

FARO X330 Laser Scanners at the Lake Saxon Sinkhole.

For buildings, landscapes, and large objects the DHHC uses FARO X330 and X130 terrestrial laser scanners. The DHHC has been using FARO laser scanners for many years and generations of scanners, and Jorge González García, the TLS Project Manager, is certified for FARO laser scanners.

For smaller and more intricate items, artifacts, and surfaces, the DHHC uses Artec Eva, Artec Spider, and Konica-Minolta laser scanners.

Imaging

The Gigapan Epic motorized mount with a Nikon D750 taking a gigapixel image of Armenian Khachkars in Haghpat, Armenia.

The DHHC uses Nikon DSLR cameras in and to document our projects. Using the DSLRs the DHHC can do photogrammetry for objects and buildings, create gigapixel images with the Gigapan automated panorama mount, attach GNSS data to spatially place each photo and create photo reports, and do reflectance transformation imaging for surfaces.

The DHHC takes imaging to the skies using DJI Phantom and DJI Mavic unmanned aerial vehicles flown by the licensed UAV pilot Garrett Speed. The DHHC also hosts workshops on Unmanned Aerial Vehicles and their use at the University of South Florida, the September workshop page can be seen here

For UAV and DSLR photogrammetry the DHHC uses Agisoft Photoscan Professional.

In addition to standard RGB imaging the DHHC has a FLIR thermal infrared camera for detecting surface temperatures.

Geospatial Analysis

DHHC Co-Director Lori Collins with the Trimble Geo7x used to collect GNSS data at the Lake Saxon Sinkhole.

The DHHC uses Trimble Geo7x data loggers and antennas to georeference features and scanning and photogrammetry work.

For analyzing the data we collect, we utilize ArcGIS and its suite of software to analyze LiDAR data, GNSS data, imagery, and many more types of spatial data. Richard McKenzie in the DHHC is a site license manager for ArcGIS products, and goes to the ESRI User Conference every year to keep up with the abilities and best practices used in GIS.

The DHHC uses more than just ArcGIS, including ENVI for spectral analysis, Cloud Compare for point clouds, Trimble Pathfinder for GNSS data, and Bentley PointTools for point cloud visualization.
