Document Type and Number:
Japanese Patent JP7428870
Kind Code:
B2
Abstract:
To provide a tire wear degree estimating device capable of accurately estimating the wear degree of various kinds of tires even if data amount used for learning is small, a tire wear degree learning device, a tire wear degree estimating method, and a learned model producing method and a program.SOLUTION: A tread surface image obtaining portion 64 obtains a tread surface image showing a tread surface of a tire. A tread surface interest region specifying portion 66 specifies a tread surface interest region showing a tread surface slip sign in the tread surface image. A target input image generating portion 68 generates a target input image that is an image of the tread surface interest region of predetermined pixels. An estimating portion 70 estimates a wear degree of a tire, on the basis of output when the target input image is inputted in a mechanical learning model 50 that has been learned.SELECTED DRAWING: Figure 7
