The DotProduct DPI-8X is a highly accurate standalone 3D scanner. However, for larger scan jobs and/or jobs with the strictest tolerances, we often recommend implementing targets for the absolute best results. This helps to reduce potential drift within the scan and provides a scale verification within the data. However, this typically means a lot of additional effort before and after the scan session. Mounting targets, taking measurements, calculating control points, preparing targeting files, and post-processing the targets into the data can be a very time-consuming and laborious process for each scan. Even worse, if one measurement or control point is even slightly off, this can create results worse than if no targets had been used at all.
Enter the AccuScale-DP from Brunson Instrument Company This revolutionary scale bar kit, paired with the intelligence of Phi.3D 2.1 & up, achieves all of the benefits of scale bar targeting, without any of the challenges and risks of traditional targeting mentioned above. This scale bar targeting workflow is impressively simple:

This scale bar targeting workflow is impressively simple:
- Set up the scale bars at maximum distances within your scene along each axis.
- Capture each target at least once during scanning (turning green, red, & blue).
- Specify the environment temperature in Phi.3D (with the included digital thermometer).
- Optimize with the target locations and exact distances automatically used a a reference.
These kits come in a set of six 1-meter bars and can be assembled in any configurations from there. For example, if you are scanning a room in all three dimensions, you would likely want to set up three 2-meter bars on on each axis. However, if you are scanning a stretch of piping along a wall, you may want to set up one 2-meter bar on the z-axis and one 4-meter bar along the pipe, or maybe even one 6-meter bar for maximum distance on one axis. You have complete flexibility here, and only need to make sure each bar has the same colored targets on each end. Please see below for the full components of the kit:
While the kit can add value to almost any scan, there are certain jobs that are a perfect fit for this technology. One such application is crime scene mapping and forensic reconstruction. With a need for highly accurate data and a hard reference to scale within the scene, the AccuScale-DP is a perfect fit. In a recent webinar from the IAFSM (International Association of Forensic and Security Metrology), we see the kit put to the test for ISO 17020 Accreditation. Tested against the results of a Leica ScanStation C10 tripod laser scanner, the measurements were within 2-3 mm of each other, with both devices achieving similar accuracies of about 99.75%. Please see below for the full webinar on use of the DPI-8X and the AccuScale-DP for forensic mapping, with the validation procedure and results starting about 23 minutes in:
