Abstract
An attitude determining device outputs a notification signal if, in an image that an imaging device has captured of a predetermined attitude determining pattern formed by a light distribution variable lamp that illuminates a region ahead of a vehicle with light, a position of the attitude determining pattern in a direction about an optical axis of the imaging device deviates from a normal position by no less than a predetermined amount.
Claims6
An attitude determining method, comprising:
- forming an attitude determining pattern by a light distribution variable lamp that illuminates a with light whereby the attitude determining pattern is formed on a screen disposed at a certain distance from the light distribution variable lamp;
- capturing an image of the attitude determining pattern by an imaging device;
- and
- outputting a notification signal if, in the image captured by the imaging device, a position of the attitude determining pattern in a direction of rotation with an optical axis of the imaging device deviates from a normal position by no less than a predetermined amount.
