Issue
Secondary calibration fiducial position and initial camera calibration
Solution
Move the camera over the secondary calibration fiducial and capture its position.
What This Step Does
This step records the position of the secondary fiducial on the staging plate.
By measuring two known fiducials, OpenPnP can determine the orientation and scale of the staging plate relative to the machine.
Move the Camera Over the Secondary Fiducial
Use the Machine Controls to jog the top camera over the secondary fiducial.
Use smaller jog increments as you approach the center.
Detect the Fiducial
Adjust the Feature Diameter setting.
You can either:
- Manually adjust the diameter
- Enter a specific value
- Use the automatic scan tool
During the scan:
- A dotted red circle begins small
- The circle gradually grows larger
- When a circle is detected it becomes solid green
- The system continues scanning for a better match until it completes and gives us it's best guess at the circle.
- Adjust the feature diameter up and down to confirm the circle is correct for the primary fiducial.
Good to Know
The automatic scan often finds a good starting point, but it can occasionally detect the wrong circle.
Always visually confirm the green circle matches the fiducial before continuing.
Accept the Calibration
Once the circle correctly matches the fiducial, click:
OpenPnP will briefly jog around the fiducial to calculate its position.
Complete the Calibration
Once the process finishes and the issue is marked as Solved, click:
