Automatic Three-Circle Calibration ​

Overview ​

Automatic three-circle calibration calibrates the pixel scale by automatically recognizing standard circles in the Vision Area. Compared to manual three-circle calibration, the automatic method reduces manual effort and improves calibration efficiency.

Important

Automatic three-circle calibration is only available on SP Fully Automatic Series machines. EV Semi-Automatic and C Manual series machines do not support this feature. Please use Manual Three-Circle Calibration instead.

Prerequisites ​

  • Verify that the machine is an SP Fully Automatic Series model
  • Prepare a standard calibration target with clearly visible circle outlines
  • Ensure the calibration target surface is clean, with no visible scratches or stains
  • Place the calibration target within the machine's measurement range

Steps ​

Step 1: Enter Automatic Three-Circle Calibration ​

  1. Click Calibration in the menu bar
  2. Select Vision Calibration - Auto Three Circles

Easson2D enter automatic three-circle calibration

Step 2: Generate Standard Circles ​

  1. Find a standard circle in the Vision Area
  2. Position the standard circle within the circle frame
  3. Click the left mouse button to generate a circle

Easson2D generate standard circle

  1. Move the stage to find a second standard circle and generate it in the same way
  2. Generate a third standard circle

Step 3: Complete Calibration ​

After generating three standard circles, click the right mouse button to confirm. The software will automatically calculate and complete the calibration.

Note

After automatic three-circle calibration completes, the software automatically updates the pixel scale, and subsequent measurements will be calculated based on the new calibration parameters.

Verification ​

After calibration, you can check the updated pixel scale values in the relevant software interface to confirm that the calibration has taken effect.

Notes ​

  • This feature is only available on SP Fully Automatic Series machines; use manual three-circle calibration for other series
  • The three circles should be distributed across different positions in the Vision Area to improve calibration accuracy
  • Make sure each circle is fully visible within the circle frame before clicking the left button to generate it
  • If a generated circle is unsatisfactory, you can regenerate it before proceeding
  • Calibration must be redone after changing magnification or camera parameters
