ACTIVE 3D MONITORING SYSTEM FOR TRAFFIC DETECTION
First Claim
1. A method for detecting the presence of an object in a detection zone using a traffic detection system, the method comprising:
- providing said traffic detection system including an optical unit havingan emitter module emitting pulses within a predetermined field of emission;
a receiver module receiving a part of the pulses reflected by an object in said field of emission toward a field of view of said receiver module, said field of view including a plurality of adjacent detection channels, said receiver module acquiring and converting said 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;
providing a status overlay image for said field of view including said image and a visual indication on said image of an outline of said plurality of adjacent detection channels;
positioning the field of view of said receiver module to cover said detection zone using said status overlay image;
obtaining said plurality of digital signal waveforms using said traffic detection system;
detecting a signal echo in one of said digital signal waveforms at a position within said field of view, said signal echo being caused by said presence of said object in said field of view;
determining a location in said field of view for said object using said position;
storing said location for said object.

Abstract
The traffic detection system includes an optical unit having an emitter module emitting pulses; a receiver module having a field of view including a plurality of adjacent detection channels receiving pulses reflected by an object and acquiring and converting the received pulses into a corresponding plurality of a digital signal waveforms; an image sensing module providing an image. The method comprises providing a status overlay image 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 to cover the detection zone using the status overlay image; obtaining the plurality of digital signal waveforms; detecting a signal echo caused by an object in one of the digital signal waveforms at a position within the field of view; determining a location for the object using the position; storing the location for the object.
