Abstract

An apparatus for vehicle-mounted camera calibration includes a floor and a display. An automobile is to be stopped in a predetermined stopping area on the floor. The display is disposed outside the predetermined stopping area on the floor. The display is configured to present a display pattern for calibration of a vehicle-mounted camera mounted in the automobile. The display is configured to change the display pattern in accordance with specifications of the automobile and specifications of the vehicle-mounted camera.

First claim

The invention claimed is:

1. An apparatus for vehicle-mounted camera calibration, the apparatus comprising:
a floor on which a vehicle is to be stopped in a predetermined stopping area,
a display controller configured to:
receive first specification information of the vehicle from the vehicle;
determine a display pattern for calibration of a vehicle-mounted camera mounted in the vehicle based on second specification information of the vehicle-mounted camera and the first specification information, the second specification information including information relating to at least one of (i) kind of the vehicle-mounted camera and (ii) mounting position of the vehicle-mounted camera; and
instruct a display to display the display pattern,

wherein the display is disposed outside the predetermined stopping area on the floor, and the display is configured to present the display pattern for calibration of the vehicle-mounted camera mounted in the vehicle.

2. The apparatus for vehicle-mounted camera calibration according to claim 1 , wherein
at least one of a space in front of the predetermined stopping area on the floor or a space behind the predetermined stopping area on the floor constitutes an entry path and an exit path of the vehicle, and
the display is disposed in a space that does not include the entry path or the exit path on the floor.

3. The apparatus for vehicle-mounted camera calibration according to claim 2 , wherein
the space behind the predetermined stopping area on the floor constitutes the entry path and the space in front of the predetermined stopping area on the floor constitutes the exit path, and
the display is disposed outside the predetermined stopping area on the left and right sides of the predetermined stopping area on the floor.

4. The apparatus for vehicle-mounted camera calibration according to claim 1 , further comprising a detecting unit configured to detect a stopping position of the vehicle in the predetermined stopping area and transmit positional information relating to the stopping position to the display controller, wherein
the display controller adjusts a display position of the display pattern on the display in accordance with the positional information.

5. The apparatus for vehicle-mounted camera calibration according to claim 2 , further comprising a detecting unit configured to detect a stopping position of the vehicle in the predetermined stopping area and transmit positional information relating to the stopping position to the display controller, wherein
the display controller adjusts a display position of the display pattern on the display in accordance with the positional information.

6. The apparatus for vehicle-mounted camera calibration according to claim 3 , further comprising a detecting unit configured to detect a stopping position of the vehicle in the predetermined stopping area and transmit positional information relating to the stopping position to the display controller, wherein
the display controller adjusts a display position of the display pattern on the display in accordance with the positional information.

7. A method for vehicle-mounted camera calibration using the apparatus for vehicle-mounted camera calibration according to claim 1 , the method comprising:
acquiring the first specification information and the second specification information and the specifications of the vehicle-mounted camera; and
presenting the display pattern corresponding to the acquired specification information on the display.

8. The method for vehicle-mounted camera calibration according to claim 7 , further comprising:
detecting a stopping position of the vehicle in the predetermined stopping area; and
adjusting a display position of the display pattern on the display in accordance with the detected stopping position.

9. The apparatus for vehicle-mounted camera calibration according to claim 1 , wherein the display includes a plurality of light emitting diode panels.

10. The apparatus for vehicle-mounted camera calibration according to claim 1 ,
wherein the display controller is configured to determine the display pattern further based on third specification information of the vehicle, the third specification information including information relating to model of the vehicle.

11. The apparatus for vehicle-mounted camera calibration according to claim 1 ,
wherein the display controller is configured to receive the first specification information from an integrated circuit tag attached to the vehicle.

12. The apparatus for vehicle-mounted camera calibration according to claim 1 ,
wherein the first specification information indicates information for identifying the vehicle.

13. The apparatus for vehicle-mounted camera calibration according to claim 1 , wherein the display controller stores a plurality of pieces of pattern information relating to the display patterns, and wherein each of the plurality of pieces of pattern information is associated with specification information relating to the specifications of the vehicle and the specifications of the vehicle-mounted camera.

14. The apparatus for vehicle-mounted camera calibration according to claim 13 , wherein the display controller determines the display pattern by selecting one or more pieces of pattern information that corresponds to the specification of the vehicle and the specification of the vehicle-mounted camera.

15. The apparatus for vehicle-mounted camera calibration according to claim 1 , wherein the first specification of the vehicle includes information relating to model of the vehicle.

16. The apparatus for vehicle-mounted camera calibration according to claim 1 , wherein the second specification information includes information relating to kind of the vehicle-mounted camera.
