An Automatic System for the Definition of the Setting Rules for Speeds Diagrams

In order to find speed diagrams composition rules, the autors took some observations through a portable videocamera on some suitable geometric design elements. The large amount of examinde observation and the need to extend the experiments to long recording and different environmental situations have brought to the automatica data collection system for the flow parameters. In this paper, after a description of used hardware and algoritms, are reported the result obtained with a sequence of about 320 frames from the movie carried out on the S.S. 223.
