Targets and Scanning

Targets are physical objects that you set up on site that scanning software uses to tie together multiple scans. The process of tying together scans is called “registration.” If you have set up your targets correctly, the software will be

Calibration

Selective sections from GSA BIM Guide Series 03 – BIM Guide For 3D Imaging Calibration Errors from an improperly calibrated instrument are systematic errors and result in an offset or bias in the measurements. This offset may be constant, linear,

3D Imaging (laser scanning) vs. Traditional As-Built Documentation Methods

Selective sections from GSA BIM Guide Series 03 – BIM Guide For 3D Imaging   The economic decision to use 3D imaging systems versus other methods depends on several factors…. Important factors affecting the decision include project requirements (e.g., measurement

What is 3D Imaging (Laser Scanning)

Selective sections from GSA BIM Guide Series 03 – BIM Guide For 3D Imaging The benefits of determining the spatial environment and as-built conditions have played a key role in reducing costs and delivering a higher quality engineering effort. 3D

Accuracy of Measurement

Selective sections from GSA BIM Guide Series 03 – BIM Guide For 3D Imaging 3.1.1. Sources of Error All measurements contain errors. Even measurements from a calibrated instrument are subject to random fluctuations or “noise”. Besides random errors, systematic errors
