ACTIVE 3D MONITORING SYSTEM FOR TRAFFIC DETECTION

摘要

There is provided a system and a method for detecting the presence of an object in a detection zone using a traffic detection system. The traffic detection system includes an optical unit having an emitter module emitting pulses within a predetermined field of emission; a receiver module receiving a part of the pulses reflected by an object in the field of emission toward a field of view of the receiver module, the field of view including a plurality of adjacent detection channels, the receiver module acquiring and converting the received pulses into a corresponding plurality of a digital signal waveforms; an image sensing module providing an image that encompasses the field of emission of the emitter module and the field of view of the receiver module. The method comprises providing a status overlay image for the field of view including the image and a visual indication on the image of an outline of the plurality of adjacent detection channels; positioning the field of view of the receiver module to cover the detection zone using the status overlay image; obtaining the plurality of digital signal waveforms using the traffic detection system; detecting a signal echo in one of the digital signal waveforms at a position within the field of view, the signal echo being caused by the presence of the object in the field of view; determining a location in the field of view for the object using the position; storing the location for the object.
