Abstract: A lighting unit includes a plurality of light sources that respectively emit plural rays of illumination light. An imaging unit that simultaneously images plural rays of reflected light obtained by the plural rays of illumination light being reflected by a subject so as to obtain information about a plurality of colors, and generates a captured image including the information about the plurality of colors. A memory stores sensitivity information items that correspond to the plurality of light sources respectively. An arithmetic unit performs an arithmetic operation to generate a plurality of separated images from the captured image by using the sensitivity information items. The plurality of separated images correspond to the plurality of light sources respectively, and each of the plurality of separated images only includes information about a corresponding one of the plural rays of reflected light.

Abstract: A monitoring system includes an axle weight measurer and a state estimator. The axle weight measurer detects a surface displacement of a road from a first captured image obtained by imaging the road when a vehicle passes at a predetermined spot of a structure having the road that the vehicle passes, and calculates an axle weight of the vehicle from the surface displacement and a displacement coefficient of the road. The state estimator generates an axle weight distribution from the axle weight calculated by the axle weight measurer, and estimates a deterioration degree of the structure, using the axle weight distribution.

Abstract: An axle-load measuring apparatus measures an axle load of a vehicle by using a captured image where a road and the vehicle on the road are imaged, and the axle-load measuring apparatus includes a displacement calculator, a correction information obtaining unit, and an axle-load calculator. The displacement calculator detects a displacement of the road by using the captured image. The displacement is caused by receiving the axle load. The correction information obtaining unit obtains correction information. An axle-load calculator calculates the axle load by using the displacement and the correction information.

Abstract: An appearance inspection apparatus includes a lighting unit, an imaging unit, a memory, an operating unit, a detecting unit, and a determination unit. The lighting unit has a plurality of light sources emitting single-wavelength light with relative spectral distributions different from one another, and substantially simultaneously irradiates a photographic subject with illumination light. The imaging unit captures light discharged by the photographic subject. The memory stores information about sensitivity characteristics of the imaging unit for each color. The operating unit separates an image into a first, a second, and a third image, for each component of the single-wavelength light, using the information. The detecting detects information about a specific area of the photographic subject using the first and the second image. The determination unit extracts an amount of image characteristics corresponding to a characteristic part present in the specific area using the first and the third image.

Abstract: A double tire determination device includes an image input unit and a determination unit. The image input unit receives input of a captured image including a tire mounted on a vehicle. The determination unit determines whether the tire is a double tire, based on a ratio between a first area and a second area. The first area is an area of a first wheel region that is a part of a region of a wheel holding the tire and that is located on a side in a first direction with respect to a position of a rotation center of the tire. The second area is an area of a second wheel region that is a part of the region of the wheel holding the tire and that is located on a side in a second direction, which is opposite to the first direction, with respect to the position of the rotation center.

Abstract: A load meter includes a detector, a storage unit, and a load calculator. The detector detects, by using a captured image obtained by capturing a road and a vehicle present on the road, a displacement amount in the captured image, the displacement amount corresponding to displacement caused on the road by application of a load of the vehicle. The storage unit stores information indicating a relation between the load and the displacement amount. The load calculator calculates the load based on the displacement amount and the information.

Abstract: A displacement measuring apparatus measures a displacement of a measurement object by using a captured image where the measurement object and a load object are imaged. The displacement is caused by the load object in contact with the measurement object at a contact position. The displacement measuring apparatus includes a position detector, an area setting unit and a displacement calculator. The position detector detects a position, of the load object, in the captured image. The area setting unit sets a position and a size of a detection area in the captured image by using distance information and the position of the load object detected by the position detector, the distance information spatially indicating a distance between the measurement object when the load object is not on the measurement object and an imaging device that generates the captured image. The displacement calculator calculates the displacement by using only an image in the detection area in the captured image.

Abstract: An imaging apparatus includes an imaging unit, a detector, a calculator, and a controller. The imaging unit captures an image of a road on which a vehicle runs, and generates the captured image of the road. The detector detects a contact position at which the vehicle is in contact with the road in the captured image. The calculator calculates a first brightness range based on brightness distribution in a first road surface area on the road and the first road surface area includes the contact position. The controller determines an imaging condition for the imaging unit based on the first brightness range, and controls the imaging unit using the determined imaging condition.
