4.3.3 Pre-scan points

Once the calibration is complete, you can start scanning. When scanning, first
collect and scan the mark points on the surface of the workpiece to establish the
coordinates and positioning of the workpiece. This step is called pre-scan points
(this step can be skipped and scan laser patch (dot) directly.

The role of the pre-scan markers is to establish the positional relationship of each
face of the workpiece, and to collect the positioned mark points, so that the
subsequent scanning laser patch (dot) is easier to perform, and the transition
from face to face is more convenient. Pre-scan points can use the software's point
optimization function to increase the accuracy of the scan.

Click “Mark Point” and “Start” to start to scan the mark points. After the
scanning is completed, click “Stop”-“Optimization”, as shown in Figure 4-19.

Figure4- 19 Pre-scan points

place it in the safety protection box.
