| Abstract: | In this paper the design and implementation of the testing system of helmet-mounted displays are introduced. The testing principles and structure of the system are also shown in this paper. The key techniques of the practical testing system are demonstrated emphatically. The edge detection by SUSAN algorithm and the sub-pixel algorithm of the Gaussian curve fitting based on the character of CCD are applied synthetically for cross localization in the testing system. The testing system reaches the requirement of practical use. |
