5.3.3
Choose a desired resolution
Desired resolution is analogous to a ± dimension tolerance in a technical drawing.
Choosing a smaller tolerance will result in a more accurate scan but also results in longer scan times and
larger file sizes. For example, you may choose ±0.001” resolution for a precision mechanical
connection; however, ±0.005” might be okay for recreating a cast surface and ±0.015” might be just fine
for purely aesthetic recreation.
5.3.4
Choose Units
You can choose either Inches or Millimeters. This information will be embedded in the .tsi image.
5.3.5
Pixels / Resolution
This is the minimum number of pixels needed to determine the presence of a feature – for example an
edge. This is used by CNC Scanner during mosaic assembly. The default value is 3.5.
You can experiment with adjusting this value. Increasing this value allows you to increase the working
distance of the camera; however, it will also start to blur edges and reduce the accuracy you can achieve
from measurements in the scan.
