Abstract
In a method for determining an installation position of a portable information terminal on a vehicle, a present camera image showing a camera image at a present position of the camera of the portable information terminal installed on the vehicle is acquired. It is determined, based on a position of a predetermined vehicle component of the vehicle in the present camera image, whether or not the portable information terminal is installed at a predetermined installation position on the vehicle. It is notified from the portable information terminal that the portable information terminal is not installed at the predetermined installation position if it is determined that the portable information terminal is not installed at the predetermined installation position.
Claims20
A method for determining an installation position of a portable information terminal on a vehicle, the method comprising:
- acquiring a present camera image showing a camera image at a present position of a camera of the portable information terminal installed on the vehicle;
- determining, based on a position of a predetermined vehicle component of the vehicle in the present camera image, whether or not the portable information terminal is installed at a predetermined installation position on the vehicle;
- and
- notifying from the portable information terminal that the portable information terminal is not installed at the predetermined installation position if it is determined that the portable information terminal is not installed at the predetermined installation position, wherein
- the portable information terminal has a communication function,
- the method is executed as a controller of the portable information terminal reads a program, and
- the program is downloaded to the portable information terminal from a server of a website via a communication line.
A method for determining an installation position of a portable information terminal on a vehicle, the method comprising:
- acquiring a present camera image showing a camera image at a present position of a camera of the portable information terminal installed on the vehicle;
- determining, based on a position of a predetermined vehicle component of the vehicle in the present camera image, whether or not the portable information terminal is installed at a predetermined installation position on the vehicle;
- and
- notifying from the portable information terminal that the portable information terminal is not installed at the predetermined installation position if it is determined that the portable information terminal is not installed at the predetermined installation position, wherein
- the determining of the predetermined installation position further includes
- extracting plural feature points set on the predetermined vehicle component from the present camera image acquired by the camera of the portable information terminal,
- calculating present position coordinates expressing three-dimensional coordinates of a present position of the portable information terminal from two-dimensional coordinates of each of the feature points that are extracted in the extracting of the plural feature points, and
- determining whether or not the present position coordinates of the portable information terminal that are calculated in the calculating of the present position coordinates coincide with reference position coordinates expressing three-dimensional coordinates of the predetermined installation position.
