Vehicle imaging system, vehicle imaging method and device, program, and recording medium
First Claim
1. A vehicle imaging device that detects a window of a vehicle utilizing a laser displacement sensor which emits a laser beam which scans a side of the vehicle in a height direction of the vehicle, receives a beam reflected by the vehicle, and measures a distance from the laser displacement sensor to a reflection point on the vehicle, at which the laser beam was reflected, wherein:
- the vehicle imaging device is configured to;
detect a change in the distance from the laser displacement sensor to the reflection point on the vehicle; and
when the change in the distance from the laser displacement sensor to the reflection point on the vehicle being detected, send a trigger for imaging the vehicle from the side of the vehicle.

Abstract
A system includes a laser displacement sensor which is provided on a shoulder of a roadway, emits a laser beam which scans a roadway space in a height direction thereof, receives a beam reflected by an object which is present in the roadway space, and measures a distance up to a reflection point on the object, at which the laser beam was reflected; and a vehicle window detection device that detects a window of the vehicle based on the distance measured by the laser displacement sensor. The vehicle window detection device detects the window of the vehicle based on a change in a distance in a horizontal direction from the laser displacement sensor to the reflection point after the vehicle in the roadway space was detected.
