3D characterization of rain by means of static image processing with projected shadows

In ultrasonic outdoor applications, the propagation of the ultrasonic wave could be affected by the rain, so that, it is necessary to develop a system for characterization of the most significant rain's parameters, such as the three-dimensional Cartesian location of the raindrops respect an origin point, as well as their size and rain's density. Thus, a relationship between the characteristics of the ultrasonic wave and the conditions of the rain could be established.
