Abstract
An imaging system utilizes a plurality of sensors capable of sensing objects within a field of view about a sight line. At least two sensors have different sight lines with the sight lines having known relative positions. Each sensor produces signals corresponding to positions of objects within a field of view over time. At least one sensor signal memory receives those signals and stores them in a manner enabling concurrent access to signals received from any selected combination of sensors. The processing unit and associated memory contain at least one program for selecting sensor signals from a sensor signal memory. Preferably motion detectors are provided for determining vibration, flexure or movement of each sensor. A normalizing means is preferably provided to adjust the sensor or make an appropriate modification of the signal received from the sensor.
