针对零重力条件下天线型面精度问题,将天线置于盛水容器中,采用近景摄影测量的方法,通过模拟零重力环境,测量得出某天线在该模拟环境下的型面精度数据.文中采用双介质摄影测量共线方程,然后设计相应的测量方案,最后通过试验对水下天线进行测量验证.试验结果表明利用文中提出的水下摄影测量方法所获得的点位精度与空气中测量所获得的精度保持一致.%With the problem of type accuracy of without the gravity condition, the article deals with the antenna in certain density water, and adopts a method of digital close-range photogrammetry. It carried out the antenna by imitating diagraph without the gravity condition. The article deduced the measured model of two-media photogrammetry collinearity equations, then designed photogrammetry project. In the end, according to the principle of that model, establishment of the diagraph project carried on an experiment to verify the underwater antenna. The result shows that it can keep consistent between the underwater photogrammetry given in the text and the need of the accuracy measured in the air in point accuracy.
