Abstract
The authors present the results of their research into photogrammetric documents based on synchronic digital images. Examples presented
in the paper indicate the value of synchronic stereophotography in registering phenomena connected with liquids. Combining synchronic
stereophotography with photogrammetric methods has allowed the authors to develop an application useful for monitoring the flow
of a liquid in an open channel. The paper is supplemented by the scientific approach to the development of a stereo pair using a
proprietary algorithm and data elaboration. The tasks performed allow an assessment of the accuracy of the results obtained and indicate
significant usefulness of photogrammetry and synchronic photography methods in liquids measurements and monitoring.
Keywords: flow in open channels; close-range photogrammetry; SVD; essential matrix; eight-point algorithm.
