The issue of imagery data collection and its implementation in photogrammetric studies with the use of unmanned aerial vehicles is still valid and provides a wide field of research in the creation of new and expansion of existing solutions. It is particulary important to increase the accuracy of photogrammetric products. So far, in photogrammetric applications, low altitude unmanned aerial vehicles had been used. Compact digital cameras had acquired single, high-resolution imagery. . Data obtained from low altitudes were often (and still are) used in mapping and 3D modeling.. Due to the low costs of flights of UAVs in comparison with traditional flights, applications of such platforms  are also attractive for many remote sensing applications . However, due to the use of non-metric video cameras, one of the main problems of the automations of the video data processing, is quite poor radiometric video sequences quality. The article addresses the issue of assessing the quality of the video imagery acquired from a low altitude UAV platform.. Authors presented quality Indicators dedicated to UAV video sequences.. The method is based on the analysis of the video stream, obtained in the different weather and lighting conditions. As a result of the research, an objective quality index for video acquired  from low altitudes was  determined.
