1. A vehicle monitoring apparatus comprising:
- an imager that comprises a first imager that images an image of a front of a vehicle approaching a predefined location, a second imager that images an image of a top of a vehicle passing through the predefined location and a third imager that images an image of a rear of a vehicle moving away from the predefined location,a determiner that determines whether or not a specific site of a vehicle exists at least in an area of the image imaged by the imager, the area being one of multiple areas into which the image is divided by one or more dividing lines that are substantially orthogonal to a direction of travel of the vehicle;
a reader that reads information on a license plate mounted to the vehicle from the area in case that the determiner determines the specific site of the vehicle exists in the area;
a vehicle location estimator that identifies a location of the vehicle in vicinity of the area at each time measurement based on the image imaged by the second imager, the vehicle being detected from the image imaged by the first imager; and
a vehicle type allocator that allocates information at the location of the vehicle, the information read from the image imaged by the first imager.

Abstract
An embodiment of a vehicle monitoring apparatus has a determiner and a reader. The determiner determines whether or not a specific site of a vehicle exists at least in an area of an image, the image imaged by an imager, the area being one of multiple areas into which the image is divided by dividing line that are substantially orthogonal to a direction of travel of the vehicle. The reader reads information on a license plate mounted to the vehicle from the area in case that the determiner determines the specific site of the vehicle is determined to exist in the area.

7. A method of monitoring a vehicle comprising:
-
imaging an image of a front of a vehicle approaching a predefined location, an image of a top of a vehicle passing through the predefined location and an image of a rear of a vehicle moving away from the predefined location; determining whether or not a specific site of a vehicle exists at least in an area of the image, the area being one of multiple areas into which the image is divided by one or more dividing lines that are substantially orthogonal to a direction of travel of the vehicle; reading information on a license plate mounted to the vehicle from the area in case it is determined that the specific site of the vehicle is exists in the area; identifying a location of the vehicle in vicinity of the area at each time measurement based on the image of the top of the vehicle, the vehicle being detected from the image of the front of the vehicle; and allocating information at the location of the vehicle, the information read from the front image of the vehicle.
