Calibration Process

After importing the PDF file, you can click to enter the calibration interface and calibrate the PDF file to the specified position on the map.

Please add at least 4 matching points, and ensure the matching points are as dispersed as possible and not aligned in a straight line to achieve the best calibration effect.

If the calibration is incorrect, you can click on a specific matching point and double-click the button to delete that matching point.
