头盔CRT显示部件互换性技术解决了显示部件差异性影响头盔组件互换性的问题,该技术以头盔实用性和互换性为标准,分析各个显示部件对头盔互换性的影响程度.通过更换各显示部件,对显示画面的中心位置、畸变、增益、亮度、聚焦等数据进行测量和分析,找出影响头盔互换性的最大因素,最终提出解决CRT互换性的方法,设计和评定CRT的一致性指标.通过实验证明实现头盔组件的互换性,进一步提高头盔显示系统的实用性和维护性.%The difference between each unit may affect the helmet module compatibility, and the interchange technique of CRT display units in Helmet-Mounted Display (HMD), Taking the practicability and interchangeability of HMD as a standard, the influence degree of each display unit on the interchangeability was analyzed. The center position of picture, distortion, gain, brightness, contrast, and focusing were measured and analysed by replacing each display unit, to find out the main factor that have effect on the interchangeability. A method for CRT replacement was put forward, which is useful for evaluating the consistency index of the CRT. The experiment proved that the interchange of HMD unit is helpful for improving the practicability and maintainability of HMD.
