Abstract
In angle grid based 2D-position measurement system, building up an accurate correspondence between the angle and the coordinates for the angle grid is very important to ensure the final accuracy of the measurement system. This paper introduces a calibration method for the angle function so as to realize the software datum. After introduce the iteration calibration algorithm, the convergence of the algorithm is discussed in detail and is proved analytically. Digital simulation has confirmed the calibration algorithm.
