ELECTRO-OPTICAL APPARATUS FOR PREVENTING VEHICLE COLLISION Russian patent published in 2012 - IPC G08G1/16 

FIELD: physics.

SUBSTANCE: apparatus has a first image input device (IID) and a system controller (SC). The apparatus further includes five electro-optical sensors (EOS), second, third and fourth IID, two blur compensating devices (BCD), a liquid-crystal display and an audio signalling device. The first and second EOS are installed with possibility of obtaining images of the scene in front of the vehicle, while the third and fourth EOS are installed with possibility of obtaining images of the scene behind the vehicle, and the fifth EOS - with possibility of obtaining images of the eyes of the driver. The IID are connected to outputs of the corresponding EOS and are configured to perform intermediate storage of the obtained image data. The first and second BCD are connected to outputs of the first and second IID, respectively, and are configured to increase clearness of the obtained image and detect moving objects. The SC is connected to outputs of the first and second BCD, the third and fourth IID, the fifth EOS and the speed sensor of the vehicle. The SC enables to select contours on the images, detect fixed objects thereon, determining their three-dimensional coordinates on pairs of stereo-images and the motion path from the change in three-dimensional coordinates of objects and detecting obstacles. The audio signalling unit and the liquid-crystal display are connected to corresponding outputs of the SC.

EFFECT: apparatus provides automatic notification of the driver on possible collision of the vehicle with an obstacle, possibility of analysing the condition of the driver in order to prevent sleeping behind the wheel.
