Lidar Scanning & GIS ServicesDigital Surveys providing a comprehensive data capture service
3D Laser Scanning is a non-contact form of measurement and documentation using a laser. The laser will reflect off of anything visible and the laser light will return to the scanner. Typically, about 250,000 points per second are collected but the scanner can collect up to 976,000 points per second.
The laser, in conjunction with the integrated digital camera, captures precise shapes, details and geometries as well as color images. The color images can be overlaid on to the laser points creating a photo-realistic 3 dimensional image. In addition, full-dome 360 degree panoramas are created. The colorized laser points can be further manipulated, analyzed and modeled when brought into a 3D CAD package.
3D laser scanners work by sending a laser beam all over the field of view. Whenever the laser beam hits a reflective surface, it is reflected back into the direction of the scanner. To determine the position in space of the captured object, the Laser Scanner Focus3D uses polar coordinates which consist of the horizontal angle, the vertical angle and the measured distance relative to the Laser Scanner’s position.
Individual scans are later registered together using common references and the resulting point cloud made up of all the project scans is able to be viewed and manipulated.
- Very high quality measurements in three dimensions.
- An accuracy of +/- 2mm at 25m, providing you with a precise virtual copy of reality.
- Amazing color overlay with less than 1 pixel overlap error.
- Having your data processed expediently, with images and scan data accessible on Webshare within 48 hours of completion of scanning project.
- Quick turn around of scans and images onto Webshare allowing access to engineers and other professionals for planning and preliminary calculations.
- Less down time due to plant shut down – plant can be scanned while still operational most times
- Limit safety risks – reduce surveyor time in high traffic areas
- Quick data access – engineers can access scan data prior to modeling to make preliminary assessments and rough calculations
- Reduce return visits to site – entire area scanned and captured digitally allowing unlimited “visits” to the site
- Laser scan data can be exported in many different formats, enabling connection to AutoCAD Architecture and Plant3D as well as many other CAD applications such as ArchiCAD, AVEVA, GeoMagic, Intergraph, Microstation, Nemetschek, PDMS, PDS, PolyWorks, Rapidform, REVIT and Rhino.
- Point clouds can attached and indexed directly in AutoCad 2011 and 2012.
- Google Sketchup can also accept point clouds using a Pointools plugin.
- Scanned 3D images can now be put securely on the Internet through password protection, thus enabling sharing of scan information with engineers, owners, operators and clients without the need of additional software.
