<p>PROBLEM TO BE SOLVED: To provide a drive recorder that employs a single camera to monitor 360 degrees around a vehicle and, should an accident occur, provides a record of conditions surrounding the vehicle when the accident occurs to permit identification of a correct cause of the accident. SOLUTION: This drive recorder includes an all-direction vision sensor (HyperOmni Vision) 12 that is installed so that it can observe 360 degrees around the vehicle as well as the driver. The HyperOmni Vision 12 includes a hyperbolic mirror 8 which is mounted perpendicularly facing downward and a camera 4 whose visual line is aligned with the center axis of the hyperbolic mirror 8 and which is mounted perpendicularly facing upward. The drive recorder further includes an A/D converter 40 that receives analog outputs from the camera 4, a monitor 48 that displays the image pictured by the camera 4, and a recording device 42 that records image data output from the camera 4, together with vehicle speed, brake condition, yaw rate, acceleration, and steering condition and the like.</p> |
