A vehicular stereoscopic imaging system provides a calculation of a distance between one or more sensors on a vehicle and a light source or object in a target scene remote from the vehicle. The imaging system may be useful in a headlamp dimmer control system, such that the headlamps, are modulated between their low and high beams in response to the calculated distance and intensities and/or colors of the light sources sensed by the sensors. The stereoscopic imaging system determines the distance to the object by comparing similarly classified signals received by each of two imaging array sensors in order to determine a relative position of an image representing the light source on each sensor. The distance to the object or light source may then be calculated as a function of the respective positions on the sensors, the focal lengths of focusing optics associated with each sensor and a predetermined separation distance between the axes of the two sensors. An associated accessory, such as a display, headlamps, windshield wipers, a warning indicator or signaling device and/or the brake system of the vehicle may be adjusted or activated in response to an output of the imaging system.

1. A vehicular imaging system comprising: at least one imaging array sensor mounted at a vehicle and directed outwardly from the vehicle, said at least one imaging array sensor sensing images of at least one object exterior of the vehicle, said at least one imaging array sensor including a first portion for receiving a first image of the at least one object and a second portion for receiving a second image of the at least one object, said first portion and second portion defining a separation distance; a first optic element positioned between said first portion and the at least one object and a second optic element positioned between said second portion and the at least one object, said first optic element having a first focal length and said second optic element having a second focal length; a control that is responsive to an output of said at least one imaging array sensor in order to capture an image of at least one object external to the vehicle and determine a distance between said at least one imaging array sensor and the at least one object external to the vehicle according to the following equation: [EQU6] where D is said distance, .DELTA. is said separation distance, f1 is said first focal length, f2 is said second focal length, xD1 is a directed distance from said first reference point to said first image and xD2 is a directed distance from said second reference point to said second image.
