The paper introduces the methods for calibrating the optical center in vision coordinate measurement-the method of varying focal length
radial alignment method and direct optical method
and compares their characteristics. It describes the principle and calibrating procedures of direct optical method in details and makes some experiments. The results show that direct optical method has the virtues of high accuracy and good repeatability. The experiments also indicate that the calibrating procedures is feasible.
