Our solution offers a grand relief for this - automated video recorders that get activated, when the car feels a bump.<br />Concept of CarRec 9000<br />Often youcan get an unwanted bump in a random parking lot.<br />
A car is equipped with 2 panorama cameras located inside the car, one located at the front windshield and one at the back. <br />Cameras<br />
Recording starts only when the car is under an alarm.<br />Recording<br />Recording is made from all angles creating a 360° view. Panorama cameras are located at the ends of the cars.<br />Cameras are equipped with night vision.<br />
The vehicle has to have a balance-aware alarm. <br />In our prototype project we used a touch and an infrared sensors to detect the bump.<br />Technical details<br />
If a sudden hit is felt by a car (another vehicle bumps the object), <br />Technical details<br />the alarm (balance or touch sensor) emits an electro-magnetic impulse to the alarm center. <br />
The impulse triggers the start of the operation:<br />the computer program activates the cameras which will be set on recording mode <br />Technical details<br />
The local data collecting device (car computer system) starts importing visual input from the cameras, saving it.<br />Technical details<br />
The recording of the visual image continues for a preconfigured time since the initiation of the alert.<br />Technical details<br /><ul><li>When the owner enters the car, he hears a continuous beep from the data collecting device. This is a sign that the system has recorded something.
The information record now can be then obtained from the system (e.g. via USB stick).</li></li></ul><li>PHIDGET SENSORS for the car to determine the bump<br />Tools used for prototype<br /><ul><li>COMPUTER for software programs to connect the Phidgets and camera
