Abstract: Disclosed is an image processing device including a hardware processor that: specifies a position of a plurality of tires of a moving vehicle from a captured image showing at least the plurality of tires of the vehicle; makes a determination of whether or not each of the plurality of tires is in contact with a ground on the basis of a position of the specified plurality of tires; and counts the number of axle of a tire in contact with the ground of the vehicle according to a result of the determination.

Abstract: An overload detection processing apparatus, an overload detection system and a computer-readable recording medium storing a program capable of determining overload more accurately are provided. An overload detection processing apparatus for determining a vehicle whose loading weight exceeds a predetermined reference is provided with a processor. The processor acquires a determination value relating to magnitude of deformation of a tire from image data obtained by photographing the tire of the vehicle and determines whether or not the loading weight of the vehicle exceeds a predetermined reference based on data corresponding to the determination value and a situation relating to the tire.

Abstract: A tire deformation calculator includes a processor. The processor (i) detects a contour of a side face of a tire attached to a wheel of a vehicle in a captured image; (ii) calculates load deformation of the contour of the side face, the load corresponding to a weight of the vehicle; (iii) identifies a circular or polygonal shape or pattern on a plane parallel to the contour of the side face; (iv) determines a conversion value for converting the identified shape or pattern in the captured image to a perfect circle or a regular polygon; (v) calculates a predetermined value indicating the load deformation of the tire in the captured image based on the conversion value; and (vi) calculates the load deformation based on the predetermined value.

Abstract: A road damage control system of the present invention includes a load detector that detects a load applied to a road from a vehicle on the road, and a server including a hardware processor that calculates road damage from the load obtained by the load detector, accumulates the calculated road damage to calculate accumulated road damage, estimates a road life from an allowable total road damage amount and the accumulated road damage, and outputs information about traffic regulation to be performed on the road to extend the estimated road life.
