摘　　要：阐述了头盔显示器检查仪的测量原理和系统结构。重点说明了实际检查仪中的关键技术,介绍了应用SU-SAN算子进行边缘检测和根据CCD特性进行高斯曲线拟合相结合的亚像素算法,采用该算法进行十字丝的定位,达到了实际应用的要求。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.
