Definitions

• This invention relates to systems of various angles video filming of occurrence and development of road accidents for subsequent objective examination of video records by bodies engaged in the examination or investigation of road accidents and their aftermaths.
• the most similar to the applied technical solution is the method and device for collecting, analyzing and storing information from board of a car for the road accident reconstruction with an aim of its subsequent examination by courts, insurance companies, etc. (Application PCT/US 99/12024, WO 99/62741).
• the ignition is on, two wide-angle digital video cameras installed in the car front and rear begin operating.
• the video information recorded in a digital form is ciphered and saved on a hard disk that implies that it can be accessed only with the help of an appropriate key.
• the video image can be synchronized with readings of velocity, deceleration (overloads), safety belts sensors, as well as with the current time.
• the road accident therefore, is registered in the form of video records from board of a car involved in an accident, for their subsequent examination by courts, insurance companies, police, etc.
• This solution's drawbacks are its limited capabilities, as the system of road accident registration is installed on one particular car and video filming is possible only from this car certain angles. This is frequently inadequate in the all-round examination of a road accident with the purpose of finding out who was the party at fault and the extent of guilt of that party. Apart from that, a fragile media can be damaged or totally destroyed during the road accident.
• the advantage of the applied solution may be formulated as a possibility of conducting research and comparison of video fragments immediately before and after the road accident, and to obtain them not only from a given car but also from nearby cars, which came into the zone of coverage of the applied system, or from traffic lights, road posts, etc.
• we acquire a possibility based on various-angles video shooting to reveal with a maximum objectivity and in full detail reasons and development of a road accident so that to objectivity and in full detail reasons and development of a road accident so that to subsequently establish all the accompanying circumstances and the persons at fault, as well as the extent of guilt of all the participants.
• the applied method of road accidents registration consisting in the reception of signals from the emergency situation sensors by a device for recording and storage, including video information about traffic situation.
• signals from such sensors are transmitted to a radio transmitter-receiver, and further on - to similar transmitter-receivers of other vehicles or to the stationary road transmitter-receivers which are within the zone of radio signal coverage; simultaneously with that, a controlling alarm signal switches over a video camera, which is constantly working during the movement or stops of a transport vehicle, while the transmitted radio signal switches over similar video cameras installed on nearby transport vehicles or stationary video cameras to transfer and storage of the most immediate video fragments before and after the road accident from RAM to the volatile video information storage device; then, the above video information fragments are sequentially read from all the system of road accidents registration which have come into the zone covered by the radio signal and displayed on the monitor in competent structures authorized to access the saved information.
• the system of road accidents registration consisting of an optical recording device with a recorded information storage unit and emergency situation sensors.
• the system contains at least by one video camera with RAM and non-volatile video information storage device installed at least on two moving transport vehicles, wherein each video camera is connected to emergency sensors' outputs and linked to a radio transmitter-receiver, which is also connected to emergency sensors'
• the system of road accidents registration consisting of an optical recording device with a recorded information storage unit and emergency situation sensors.
• the system contains at least one video camera with RAM and non-volatile video information storage device installed on at least one moving transport vehicle and connected to accident sensors' outputs and linked to a radio transmitter-receiver, which is also connected to accident sensors' outputs, as well as at least one video camera installed on stationary road objects and connected to a radio transmitter- receiver.
• a digital wide-angle camera can be installed in the front part of a moving transport vehicle.
• an impulse radio signal transmitter-receiver can be used as a radio transmitter-receiver.
• two-dimensional accelerometers with an assigned threshold value of acceleration can be used as accident sensors.
• impact-sensitive sensors can be used as accident sensors.
• traffic lights, road posts and barriers can be used as stationary road objects.
• the applied technical solution therefore, implements a system of road accidents registration which allows by way of various-angles video recording of emergence and development of a road accident to reestablish that road accident in full objectivity and with maximum details, and thus to be positive in establishing the persons to blame, and, in particular, to collect the insurance compensation from persons to blame, or to render impossible receiving of such insurance compensation from an insurance company in a fraudulent way in case of damage or total loss of a transport vehicle.
• the applied solution enables frame-by-frame scanning of the available video fragments.
• the system does not require any costs-involving ciphering of video records, since due to multiplicity of video fragments they are virtually impossible to falsify.
• Figure 1 shows a flow-chart of the equipment intended for the system of road accidents registration.
• Fig. 2 shows a variant of positional stationing of the equipment on a transport vehicle.
• the system of road accidents registration intended for a transport vehicle contains emergency sensors 1 , in particular, a two-positional accelerometer activated when an assigned acceleration threshold has been exceeded, and an impact- sensitive sensor, which, in particular, is capable of signaling of a rear-end collision during stops near traffic lights.
• the emergency sensors' 1 outputs are connected to a system controlling a digital black-and-white wide-angle video camera 2 encompassing RAM of no less than 20 seconds of video information retrieved from a digital video camera, and a volatile video information storage device intended, for example, for storage of no less than three 20-sec video fragments.
• the outputs of emergency sensors 1 are connected to a radio transmitter-receiver 3 with a coverage range of no less than 50 m.
• a video camera 2 installed on a car or stationary road objects for example, traffic lights, posts, barriers

• the system may include stationary road video cameras if the latter are within the radio signal zone.
• video cameras 2 can be positioned not only on the windshield but also on the rear window, and along the entire perimeter of a transport vehicle.
• a Sony or, for example, Canon video camera 2 is continuously filming everything that is in its field of vision, results of filming are recorded in RAM, for example, in the form of a memory microchip of the Texas Instruments company.
• the RAM information is regularly updated.
• a sensor-accelerometer 1 manufactured, for instance, by Motorola, and preferably a two-positional one, i.e., working in two directions - along and across the car movement - is activated in cases the emergency breaking threshold is exceeded.
• An impact-sensitive emergency sensor 1 is activated in case another car bumps into a given parked car so the system takes into account a possibility of a parked car becoming a part of a road accident.
• the video information contained in RAM i.e., the most immediate information prior to the road accident
• a volatile storage device in the same way as, for example, a 20-sec interval following the signal, i.e., the most immediate information after the occurrence of a road accident.
• the same emergency signal from the sensor 1 activates the transmitter-receiver 3, its signal is received by similar transmitter-receivers 3 installed on nearby cars and stationary road objects within the range no less than 50 m.
• Each radio transmitter- receivers 3 which has received a radio signal, commands its own video camera 2 to start the video information re-recording procedure from RAM to a volatile video information storage device.
