When photogrammetry is used to research the moving target in water, one can encounter with two conditions. One of them is underwater photogrammetry, another is the photogrammetry through the big water-pot made from transmitting glass. In both cases, there is a sight glass between the taken target and camera. This glass will have an effect on the results of photogrammetry. The problems of the quality and accuracy of photogrammetry under this condition are discussed.
