摘要： A repair patch (70) is a repair patch to be attached to a tire and includes an indicator portion (31a) having color components to be extracted by a degradation state determination apparatus that includes a degradation state model and a color change database for determining a degradation state of the tire. The repair patch also includes a reinforcement portion (71) to be bonded to the tire to reinforce the tire. The indicator portion includes a medium layer having printed thereon an identifier and a color pattern having a plurality of colors applied to different positions, the plurality of colors having different sensitivities to a degradation factor.

摘要： A degradation state determination method for determining a degradation state of a target object based on a color of an indicator attached to the target object includes generating a color change database including data indicating a relationship between a change in color of the indicator and an amount of a degradation factor that causes the target object to degrade, selecting a color to be used for the indicator so that the amount of the degradation factor can be identified, acquiring an image of the indicator attached to the target object and extracting a color component from the image (S27), and determining, based on the color change database and the extracted color component, the degradation state of the target object using a degradation determination model that takes the amount of the degradation factor as an input and outputs an index of the degradation state of the target object (S30).

摘要： An indicator (31) is to be attached to a target object that is the target of determination of a degradation state, the indicator having color components to be extracted by a degradation state determination apparatus that includes a degradation state model and a color change database for determining the degradation state of the target object. The indicator includes a medium layer having printed thereon an identifier (32) and a color pattern (33) having a plurality of colors applied to different positions, the plurality of colors having different sensitivities to a degradation factor.

摘要： A degradation state determination method is for a degradation state determination apparatus to determine a degradation state of a tire mounted on a vehicle based on a color of an indicator attached to the tire. The method includes determining the degradation state of the tire, using a degradation determination model that takes an amount of a degradation factor that causes the tire to degrade as input and outputs an index of the degradation state, based on a color change database, including data indicating a relationship between a change in color of the indicator and the amount of the degradation factor, and a color component extracted from an image of the indicator attached to the tire, and proposing, based on the determined degradation state of the tire, an option that is at least one of a method and a product that are selectable when retreading the tire (S44 to S48).
