Camera Calibration Device And Method, And Vehicle
First Claim
1. A camera calibration device that performs camera calibration for projecting on a predetermined plane and synthesizing a plurality of camera images from a plurality of cameras based on results of shooting, by the plurality of cameras, of a calibration pattern to be arranged in a common shooting region between the plurality of cameras, the camera calibration device comprising:
- a checker which, based on the results of shooting, checks arrangement condition of the calibration pattern in the common shooting region; and
an indication signal outputter which outputs an indication signal for indicating information according to a result of checking by the checker to outside.

Abstract
A camera calibration device performs camera calibration for projecting a plurality of camera images from a plurality of cameras onto a predetermined surface to combine them on the basis of the results after calibration patterns to be arranged in a common photographing area of the cameras are photographed by each of the cameras. The camera calibration device judges where or not the calibration patterns are observed by the cameras on the basis of the photographed results. If judging that the calibration patterns are not observed, the camera calibration device creates the content of an instruction to contain the calibration patterns in the common photographing area to allow the cameras to observe the contained calibration patterns on the basis of the photographed results and notifies the instruction content to an operator who is in charge of the arrangement operation of the calibration patterns.
