摘要: 由于空间虚拟轴没有直接的实体存在,不能对其采取传统的接触式测量方法。为此,以星载相机的虚拟视轴测量为实例展开研究,针对被测轴所具有的光学特征,借助通用仪器将其引出,并选择恰当的用于姿态关系中间传递的可测对象,基于可测数据建立各对象的数学模型,通过分析不同对象的内在关联性,推导出空间虚拟轴的准确数学表达。由于推导过程贴合现有条件,因此这一技术具备工程实用的可行性。

Abstract: Because the spatial virtual axis does not exist as a direct substantiality, the traditional technique of contact measurement can not be adopted for it. Therefore, the research on the measurement instance of virtual boresight of satelliteborne camera was carried out by using normal instrument to derive it according to its optical characteristics. Every object for transfering attitude relations was modeled based on measurable data. According to the internal relevance between every object, the precise formula of spatial virtual axis is deduced. Because of the considerate design for the existing conditions, the technique can be applied to the engineering practices.
