Abstract
A method for detecting a position of a mobile body moving on a plane includes setting X-axis and Y-axis direction reference lines on the plane, disposing a dummy mobile body on intersection points of the reference lines, detecting a position of the dummy mobile body, determining position variation amounts at the intersection points as an X-axis direction error and a Y-axis direction error based on a difference from true position data, determining X-axis and Y-axis direction error approximate formulas based on the errors to calculate errors at each position on the reference lines, detecting the position of the mobile body, correcting acquired detected X-Y coordinate data by a linear interpolation method using the X-axis and Y-axis direction error approximate formulas, and obtaining position data close to the true position of the mobile body.
