Abstract
In this paper is presented the research carried out for developed laser detection principle the road vehicles. The aim of this research is to identify the vehicles by scanning it through the vertical axe and to display the shape resulted on PC, using a graphics interface. The basic vehicle dimensions are measured with the laser sensor. Using an LT-3 Banner programmable transducer and an electronic interface designed in this purpose, experimental equipment was developed in the Road Traffic laboratory. The tests carried out with toy car and with automobiles were recorded in Lab View program. For describe the vehicle shape (at real dimensions) a matrix equation system was proposed.
The tests carried out shows the fact that the vehicles can be identified in real time, for obtain a vehicles classification used to developed traffic management systems.
As a conclusion of the research carried out is the fact that the possibilities of the real time vehicle scanning using laser sensors represent a real opportunity and an efficient method for traffic monitoring.
