1. A method for assessing a flow of a sprayed coating, comprising the steps of:
providing a coating with a plurality of tracer particles;
spraying the provided coating onto a surface;
capturing a plurality of images of the sprayed surface at a predetermined frequency within a predetermined interval of time;
processing each captured image; and
deriving at least one flow parameter of the sprayed coating from tracer particles imaged by the plurality of processed images.
