Claim One:
1. A multisensor processing system for surveillance, comprising: an enclosure for enclosing and mounting components of the system in a unified package mountable to survey a surveillance environment; a sensor mounting surface provided within the enclosure, for geometrically arranging sensors before deployment of the system into the surveillance environment; a pair of spaced-apart first sensors mounted to the mounting surface arranged to sense within a first field of view, each of the first sensors having a predetermined first resolution and a first frame rate; a second sensor mounted to the mounting surface arranged to sense within a second field of view, the second sensor having a second frame rate and a predetermined second resolution higher than the first resolution, wherein the first sensors and the second sensor are spatially positioned on the mounting surface prior to being deployed into the surveillance environment such that the second field of view of the second sensor is coextensive with at least a portion of the first field of view of the pair of spaced-apart first sensors; a signal processing subsystem within the enclosure coupled to receive signals from the first sensors and the second sensor, the signal processing subsystem including a programmed processor and memory for storing data and instructions for the processor, the processor operative to execute instructions to: (i) receive and store one or more calibration parameters containing data defining the spatial positioning of the first sensors and second sensor on the mounting surface, the respective first field of view and the second field of view, and the first frame rate and second frame rate of the first sensor and second sensor; (ii) receive sensor signals from the first sensors and the second sensor after the system is deployed into the surveillance environment; (iii) synchronize the first frame rate and second frame rate of the first sensors and the second sensor; (iv) rectify the sensor signals from the first sensors and the second sensor to determine an area of coincidence of the first field of view and the second field of view by mapping a particular portion of the first field of view captured by the first sensors and a particular portion of the second field of view captured by the second sensor to a common plane based on the one or more calibration parameters, wherein the common plane defines the area of coincidence corresponding to the particular portion of the first field of view coextensive with the particular portion of the second field of view of the second imaging sensor; (v) process the first sensor signals to determine the appearance of an object within the area of coincidence; (vi) assign an object identifier to the object appearing within the area of coincidence; (vii) generate object metadata corresponding to the persistence of the object having the particular object identifier within the area of coincidence; and (viii) provide an output comprising signals from the second sensor, the object identifier, and the object metadata for use by an external processing and data storage system, whereby the signals from the second sensor may be searched and accessed by reference to object identifiers, synchronized frames of the first and second sensors, and/or object metadata.
