Abstract
An in-vehicle device comprises an image recognizer configured to acquire an image using a camera for photographing the exterior of a vehicle and execute processing for recognizing license plate information included in the image at intervals of a predetermined period; and a period determiner configured to determine the period to perform the recognition processing on the basis of a length of time in which a license plate of another vehicle stays within a field of view of the camera.
Claims11
An in-vehicle device comprising:
- an image recognizer configured to acquire an image using a camera for photographing the exterior of a vehicle and execute processing for recognizing license plate information included in the image at intervals of a predetermined period;
- and
- a period determiner configured to determine the period to perform the recognition processing on the basis of a length of time in which a license plate of another vehicle stays within a field of view of the camera.
A control method for causing an in-vehicle device installed in a vehicle to execute:
- an image recognition step for acquiring an image using a camera for photographing the exterior of the vehicle and executing processing for recognizing license plate information included in the image at intervals of a predetermined period;
- and
- a period determination step for determining the period to perform the recognition processing on the basis of a length of time in which a license plate of another vehicle stays within a field of view of the camera.
An in-vehicle device comprising:
- an image recognizer configured to acquire an image using a camera for photographing the exterior of a vehicle and executing processing for recognizing license plate information included in the image at intervals of a predetermined period;
- an information acquirer configured to acquire environment information, which is information relating to a road environment on the periphery of the vehicle;
- and
- a period determiner configured to determine the period to perform the recognition processing on the basis of the road environment.
An in-vehicle device comprising:
- a first processor configured to acquire an image using a camera for photographing the exterior of a vehicle and executing processing for recognizing license plate information included in the image;
- a second processor configured to execute processing other than recognition of the license plate information;
- and
- an allocator configured to determine an amount of resources to be allocated to the first processor and an amount of resources to be allocated to the second processor on the basis of a length of time in which a license plate of another vehicle stays within a field of view of the camera.
