Evaluating the Structure from Motion Technique for Measurement of Bed Morphology in Physical Model Studies

The selection of instrumentation for data acquisition in physical model studies depends on type and resolution to be recorded, time frame the study, available alternatives, availability skilled personnel overall budget study. recording bed levels or three-dimensional information geometry a range from simple manual gauges sophisticated laser acoustic sensors. In this Structure Motion (SfM) technique was applied, three different scales study objectives, as cheap, quicker, easy use satisfactorily precise alternative 3D point form colour coded dense cloud representing especially river model. accuracy generated with SfM were also assessed by comparing obtained measurement using conventional surveying models results found very promising.
