Turbulent flow height measurement with stereo vision

Jašarević, Ajdin (author), Hočevar, Marko (author), Rak, Gašper (author)

This paper describes the process of 3D analysis of two water currents with method of photogrammetry. Photogrammetry is used in fields such as architecture, engineering, police investigation, preserving cultural heritage, military and geology. This method can be used in military to reconstruct a site with traces of shrapnel or various projectiles. In our case we tried to measure height of turbulent flow, where two currents collided at the angle of 90°. In first section we introduce our problem and method. Second section describes method of photogrammetry and basics of torrential flows. In third section we describe our experiment. Fourth section describes the course of getting 3D model. In fifth section we analyze results and in sixth section, a conclusion is given.
