摘要： PROBLEM TO BE SOLVED: To provide a vehicle inspection device including a reference mark detection technique for, in the detection of the feature amount of a scratch on the side face of a wheel or the like, specifying the position of the scratch, or the like, based on the relationship to the absolute position. SOLUTION: The vehicle inspection device detects a feature amount on a wheel from an input image of a side face of a wheel for railway vehicles, detects the coordinate of the center of the wheel from the input image of the side face of the wheel for railway vehicles; detects a reference mark from the input image of the side face of the wheel for railway vehicles, determines the coordinate thereof; and stores the position of the feature amount determined using the coordinate of the wheel center and the coordinate of the reference mark as references. Since the reference mark which is the absolute position for specifying the position of the feature amount can be detected, it is possible to automatically inspect a vehicle.

摘要： PROBLEM TO BE SOLVED: To achieve a vehicle color determination device and a vehicle retrieval system, capable of improving data transfer efficiency and vehicle color determination accuracy in spite of an easy method independent from high-level image processing, and accurately performing vehicle color determination of a vehicle painted in a plurality of colors and vehicle color determination in a case changed in illuminance, which are problematic in use in the actual environment. SOLUTION: A vehicle color recognition part 112 receives a color image 4 from an image data receiving part 113, and acquires a license plate coordinate 242 from the file name of the color image 4. Taking the license plate coordinate 242 as a reference position, a vehicle color determination area 241 with a predetermined distance from the reference position is set, and a vehicle color is determined from color information of the vehicle color determination area 241.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle inspection apparatus performing inspection by taking a photograph of the side face of a vehicle, in particular, a vehicle inspection device forming an inspection image of the entire circumference of each wheel suitable for inspection, from among a plurality of partial images by correction, based on the rotation angles of the wheels among a plurality of cameras through measurement of the amount of abrasion that differs for each wheel, and the radius of the wheels. SOLUTION: The vehicle inspection apparatus includes an image acquisition device disposed along a railway track to photograph a wheel image of the side face of a wheel of a vehicle traveling along the railway track; an image-storing device for storing the image photographed by the image-photographing device; and an image-processing device for performing image processing. The image storing device preliminarily stores a facing image of a reference wheel without abrasion. The image-processing device generates a facing image that faces the wheel, by applying planar projective transformation to the wheel image obtained by the image acquisition device; estimates the position of an axle of the wheel in the facing image; and stores, in the image storage device, an image in which the estimated axle position is corrected to coincide with the axle position of the facing image of the reference wheel, without abrasion stored in the image storage means.
