Definitions

  • the present invention relates to an apparatus for video- recording fortuitous events related to moving means of any nature.
  • the present invention can apply to any motor vehicle travelling on the road, on railways, in the air or in the sea, for recording events such as accidents or damages that, obviously, have a fortuitous occurrence and therefore cannot be established a priori.
  • the video-signal sequence from telecamera to the memory could be stopped upon intervention of a sensor capable of recognizing anomalies in driving due to sudden decelerations, impacts or still other events, for e.xample.
  • a sensor capable of recognizing anomalies in driving due to sudden decelerations, impacts or still other events, for e.xample.
  • a sequence of images was stored that corresponded to a time interval immediately preceding the anomaly in driving and/or simultaneous therewith. This sequence of images could then be transferred to a data recording medium and then displayed on a monitor.
  • the above described devices have shown poor reliability due to the presence of many movable mechanical parts (transducers, tape recorders) that inevitably can be damaged during an accident, thereby preventing the device from performing its task.
  • Another object of the invention is to provide an apparatus in which the operating parameters, and in particular the recording interval can be personalized in order to meet the different requirements that may occur each time, depending on the transport means on which the apparatus is installed (cars, boats, aircraft or still other vehicles).
  • a further object of the invention is to provide an apparatus that while being very flexible from an operating point of view, does not show negative repercussions in terms of operating costs.
  • FIG. 1 is a block diagram of the apparatus being the object of the present invention
  • - Fig. 2 diagra matically shows, still in the form of a block diagram, the essential operating steps of the apparatus in question.
  • an apparatus for video-recording fortuitous events related to moving means of any nature in accordance with the present invention has been generally identified by reference numeral 1.
  • Apparatus 1 comprises acquisition means 2 arranged to detect images surrounding the vehicle on which the apparatus is installed and to convert these images into corresponding electric output signals.
  • the acquisition means 2 can be made of a given number of detector members 3, such as telecameras, suitably distributed on the vehicle, so that they can offer a complete picture of the situation around the vehicle.
  • detector members 3 such as telecameras
  • the acquisition means 2 is to be installed on a car, a pair of telecameras could be provided, one of which is directed to the front and the other to the rear of the vehicle.
  • telecameras 3 preferably are microcameras of the CCD type and they are provided with wide-angle lenses 4 so that the number of cameras required for substantially viewing the whole area surrounding the vehicle may be reduced to the minimum.
  • the electric signals emitted from the image-detecting members 3 are sent to an analog-to-digital conversion block 5 arranged to input signals corresponding to the image of each detector member and generate corresponding coded output sequences.
  • Said output sequences can be stored in storing means 6 of the volatile type consisting of conventional random access memories (RAMs), for example.
  • the apparatus is also provided with sensor means 7 which is arranged to detect any sudden anomaly in driving, such as abrupt decelerations, sudden steering, impacts or still other anomalies and to generate a predetermined output control signal.
  • the processing unit 8 comprises a data compressing block operatively active on the coded output sequences from the analog-to-digital conversion block to reduce the required memory amount for storage of images in means 6.
  • the processing unit 8 is also provided with a memory management block arranged to give the storing means 6 a virtual loop structure so that sequential storage of a predetermined number of images is enabled which corresponds to a predetermined useful time interval beyond which the new coming images become superimposed on the previously stored (older) images.
  • the storing means 6 will e.xclusively retain a predetermined sequence of the events occurring in the vehicle neighbourhood, while gradually "forgetting" the earlier or older images.
  • timing means to define an interval of time following and preceding the instant at which the control signal is received by the sensor means 7.
  • the useful time interval i.e. the image recording interval in the storing means 6 is divided into a time interval preceding the fortuitous event that causes starting of said predetermined control time, and a time interval following or subsequent to the occurrence of such a fortuitous event.
  • processing unit advantageously comprises an adjustment block, by which it is possible to vary the duration of each of said time intervals preceding and following the events, in order to conform them to requirements that may occur each time.
  • the data compressing block, memory management block, timing means and adjustment block can consist of true dedicated chips or program routines to be executed by unit 8.
  • the apparatus in accordance with the invention also comprises a bulk storage unit 9, preferably consisting of at least a static hard disc in which the processing unit carries out transferring of the images contained in the storing means 6 as soon as storage of images in the storing means is inhibited.
  • a bulk storage unit 9 preferably consisting of at least a static hard disc in which the processing unit carries out transferring of the images contained in the storing means 6 as soon as storage of images in the storing means is inhibited.
  • said unit can be such organized, by virtue of appropriate software means, that a plurality of events can be managed and stored.
  • recording of each event can be disposed sequentially or organized in random access directories, and overwriting can be excluded for particular events that are judged of importance.
  • the sensor means too may comprise a predetermined number of transducers both of the force and displacement type as well as of still other nature.
  • these transducers can be responsive both to speed variations and, if suitably positioned, to deformations of parts of the vehicle structure on which they are installed.
  • the apparatus in accordance with the invention comprises a power supply unit 10 connected in circuit with the vehicle's power supply network and provided with a filtering and adjustment block for ensuring an appropriate protection from discontinuity in power supply.
  • the power supply unit 10 is provided with an emergency power supply 11 substantially representing a power supply storage capable of ensuring correct operation of apparatus ' 1 even if power supply from the network of the vehicle on which the apparatus is installed is stopped, which may frequently occur in case of accidents.
  • a manual drive element 12 is also provided for operation of the processing unit 8 so that image storage into the storing means 6 is stopped and subsequent transferring of said images to the bulk storage unit 9 is caused. This enables the recording cycle to be carried out also by intervention of an operator, both when operating tests are to be carried out and when one wishes to voluntarily store a predetermined event.
  • sensor 7 and the manual drive element or push-button 12 are connected to unit 8 upon interposition of a serial port 12 X
  • apparatus 1 can be provided with a keyboard 13 or other input means, suitably connected with unit 8, as well as with video cards and/or printer cards 14, 15 for output on a monitor 16 or an appropriate hardcopy 17.
  • apparatus 1 Under operating conditions, apparatus 1 carries out recording in the storing means 6 of the images that are progressively caught by telecameras 3. Since the storing means has a virtual-loop configuration, images stored in the memory will correspond to a given time interval.
  • sensor means 7 signals anomalies in driving or impacts and sends the corresponding signal to the processing unit 8
  • the latter intervenes in order to stop recording after a certain time interval (subsequent interval) has elapsed from occurrence of the event. In this manner recording of images relating to a time interval before and after detection of the anomaly in running is obtained.
  • the processing unit 8 transfers images to the bulk storage unit 9 thereby enabling sure data storage and the possibility of sending information relating to said images to output members such as printers or monitors.
  • the cycle is shown in a schematic manner in fig. 2 where block A identifies beginning of the procedure, block 2 the cyclic reading step of the image until stopping, due to detection of anomalies in running, block C identifies data saving in the bulk storage unit and block D end of the procedure.
  • both the overall duration of the image recording interval (useful time interval) and the duration of the recording interval following detection of the anomaly in running (subsequent or following time interval) can be adjusted at will and with great ease.
  • static hard discs are not adversely affected by vibrations and ensure a practically timeless residence of the stored data therein.
  • the apparatus can be activated even when the car engine is switched off (when the car is parked, for example) so that possible accidents (car bumping into one another or others) that may take place in the absence of witnesses, can be recorded as well.
