摘　　要：研究了采用水上拍摄方式,对水下近景摄影测量进行精密测量的理论模型。首先对已有的两种理论模型在实际应用中存在的局限性进行了分析,推导了界面法构像方程模型,并设计了相应测量方案。对水下天线进行测量试验,获得了±0.9mm的测量精度。从而验证了界面法构像方程模型的实用效果。In order to have a high level of accuracy of measurement in underwater close-range photogrammetry, a study of two varieties of theory models was researched according to the way of imaging upon the water. First, a careful analysis was made for the two varieties of models and that there were some serious limitations in practical application was found out, a third model was advanced and an in-depth study for this model was made, Second, a special project for this measurement was designed correspondingly. Finally, the underwater antenna was tested by carrying out experiment. The result of experiment showed that the precision of 3D coor- dinates measurement was 0.9mm, which validated the availability and operability in practical application with this third model.
