  • the drive recorder of the present invention is installed, the image taken by the camera is analyzed, and the vehicle speed is controlled based on the analysis result.
  • the front, side parts and vehicle occupants of the vehicle can be clearly photographed.
  • the drive recorder includes a camera 1 and an image processing device 2, and an external memory 3 and a monitor 4 can be connected to the drive recorder.
  • the external memory 3 is a non-volatile memory such as a flash memory or a hard disk.
  • the monitor 4 is a display device such as a liquid crystal display.
  • the camera 1 has a fisheye lens 1A and an image sensor such as a CCD (Charge-Coupled Device) or a CMOS (Complementary Metal-Oxide Semiconductor), and is mounted on a vehicle to photograph the surrounding environment of the vehicle and generate an image.
  • the camera 1 continuously shoots, for example, every 1/60 second frame (60 fps) to generate an image.
  • the camera 1 outputs the captured image to the image processing device 2.
  • a stereographic fisheye lens having an angle of view of 220 ° to 250 ° can be used.
  • the peripheral image is magnified about 4 times compared to the central image.
  • the stereographic projection method resembles human vision. Further, while the other projection method deforms the image toward the periphery, the stereographic projection method does not deform the image, and is therefore suitable as a lens for the camera 1 of the drive recorder.
  • the image processing device 2 has a control unit 20 and an image memory 26.
  • the control unit 20 includes a CPU (central processing unit), a ROM in which programs and the like are stored, a RAM as a work area, and the like.
  • the CPU executes the program, the functions of the image acquisition unit 21, the image compression unit 22, the image generation unit 23, and the data transfer unit 24 are realized.
  • the image acquisition unit 21 acquires a captured image from the camera 1.
  • the acquired captured image data is written in the image memory 26.
  • the captured image data can be repeatedly overwritten and written to the image memory 26 at high speed.
  • the image compression unit 22 compresses the captured image data in a predetermined compression format, for example, a JPEG (Joint Photographic Experts Group) method, and generates compressed image data.
  • the compressed image data is transferred to and stored in the external memory 3 by the data transfer unit 24.
  • the image generation unit 23 reads captured image data from the image memory 26 (or external memory 3) and generates an image for reproduction by image conversion processing. For example, the image generation unit 23 unfolds the fisheye lens image (omnidirectional image) taken by the camera 1 in a plane, arranges and combines the image on the front side of the camera 1 at the top and the image on the rear side at the bottom. Generate an image for playback (see FIG. 3).
  • the data transfer unit 24 transfers the image data for reproduction to the monitor 4.
  • the monitor 4 displays an image for reproduction.
  • FIG. 2 shows an example of installing this drive recorder in the vehicle C of an automobile.
  • the side mirrors M1 and M2 are located in front of the windshield W (windshield).
  • vehicle C is a truck, a bus, or the like without a bonnet.
  • the camera 1 is installed on the upper part of the windshield W or the front part of the vehicle on the ceiling of the vehicle so that the fisheye lens 1A faces downward. This makes it possible to photograph the front, left and right of the vehicle, the driver's seat, the passenger's seat, and the like. In addition, a portion higher than the installation height of the camera 1, for example, a traffic light or a sign can be photographed.
  • the image processing device 2, the external memory 3, and the monitor 4 can be installed at any place.
  • the camera 1 is arranged on a straight line L connecting the driver D (driver's seat) and the side mirror M1 on the opposite side of the driver's seat.
