US Patent 9151692 Asset monitoring system using multiple imagers

Asset including an arrangement for monitoring objects in an interior of the asset includes at least first and second optical imagers for obtaining images of a common area of the interior and which are spaced apart from one another, and processing circuitry coupled to the first and second imagers and arranged to derive information about objects in the interior from images obtained by the first and second imagers. A communication system may be arranged on the asset and coupled to the processing circuitry. The communication system wirelessly transmits the information about the objects to a remote facility. A location determining system may be arranged on the asset to monitor the location of the asset so that the communication system also transmits the location of the asset to the remote facility.
