Calibration of optical see-through head-mounted displays(OSTHMD)is a key issue in augmented reality domain. In the paper, several common technologies about calibration of OSTHMD are researched; their advantages and disadvantages, discussed in detail the current most commonly used OSTHMD calibration method: SPAAM, and raise a fast method about calibration of OSTHMD based on image, compared the two calibration method from algorithm complexity, with user self-assessment method, the fast method about calibration of OSTHMD based on image is considered more rapid and precise.
