METHOD FOR DETERMINING A CONFIDENCE INDEX ASSOCIATED WITH AN OBJECT DETECTED BY A SENSOR IN THE ENVIRONMENT OF A MOTOR VEHICLE

摘要

The invention relates to a method for determining a confidence index associated with an object (i) detected by a sensor, comprising steps of approximating the zone of detection by a polygon two sides of which are defined by the lateral borders bounding the angular sector of detection of this sensor, determining the centre of gravity (G) of said polygon, dividing said polygon into a plurality of triangular sub-zones each defined by two adjacent vertices of this polygon and said centre of gravity, identifying, when said sensor detects an object, the triangular sub-zone in which this object is located, determining the equation of the straight line passing through said object and being parallel to the exterior border of this triangular sub-zone, and computing a confidence index associated with said object using a decreasing function (F) of the homothetic ratio (k) with respect to said centre of gravity between said straight line and that defined by said exterior border.
