Vehicular surveillance system
View Patent ↗The invention is a vehicular surveillance system that captures images of road and vehicles in front of a vehicle as well as position and gaze of a driver. The images are captured and stored so as to enable someone to access image data captured prior to and at the time of an accident.
1. A system comprising:
a vehicle ceiling-mounted enclosure operative to enclose at least one digital camera, and a wireless transmission subsystem;
said at least one digital camera is operative to capture, simultaneously, driver images as reflected from a rear-view mirror and images outside a windshield;
said wireless transmission subsystem is operative to accept said driver images and windshield images data conveyed to it by said at least one digital camera;
said wireless transmission subsystem is operative to transmit, wirelessly, said driver images and windshield images data to a nearby wireless receiving subsystem;
said wireless receiving subsystem is operative to convey via an input/output subsystem said driver images and said windshield images data to a processing subsystem;
said processing subsystem is operative to process said driver images and said windshield images data, conveyed to it by said wireless receiving subsystem;
said processing subsystem is operative to convey processed driver images and windshield images data to a dynamic-memory subsystem; and
said dynamic memory subsystem is operative to convey said processed driver images and windshield images to a mass-storage subsystem for non-volatile storage of said processed driver images and windshield images.
2. A system as in claim 1 further comprising:
a wide-angle lens on a second digital camera is aimed at a rear window and rear cabin area.
3. A system as in claim 1 further comprising:
said at least one digital camera captures continuous video whenever a vehicle's engine is started;
said processing subsystem manages capture and storage of said driver images as reflected from a rear-view mirror and images outside a windshield;
said dynamic memory subsystem can accommodate at least some predetermined quantity of said processed driver images and windshield images data; and
said processing subsystem transfers captured and stored said processed driver images and windshield images data to said mass storage subsystem in increments of said predetermined quantity of said processed driver images and windshield images data.
4. A system as in claim 2 further comprising:
said second digital camera captures continuous rear-window video whenever a vehicle's engine is started;
said processing subsystem manages capture and storage of said second digital camera's said rear-window video output;
said dynamic memory subsystem can accommodate at least some predetermined quantity of said rear-window video output data; and
said processing subsystem transfers captured and stored said digital rear-window video output data to said mass storage subsystem in increments of said predetermined quantity of said rear window video output data.
5. A method comprising:
starting a vehicle engine;
starting one or more digital video cameras upon said vehicle engine startup;
capturing as video content images reflected by a rear-view mirror;
capturing as said video content images in front of said vehicle as detected through a windshield;
conveying by a wireless transmission subsystem data representing said video content images;
receiving by a wireless reception subsystem said data representing said video content images;
managing of said data received by a processor;
storing, dynamically, by said processor said data representing said video content images;
transferring by said processor said data to a mass-storage subsystem when quantity of data reaches some predetermined value; and
continuing capturing, storing dynamically, and transferring data to said mass storage for full duration of time said vehicle engine is running.
