To provide a tire type learning device, a tire type estimating device, a method for generating a learned model, a tire type estimating method, and a program, capable of improving estimation accuracy of a type of a tire based on an image of the tire.SOLUTION: A learning data acquisition part 34 acquires a learning image in which a tread surface of a tire is photographed. A learning area extracting part 36 extracts an area circumscribing a portion where the tire is photographed from the learning image. A learning deformation image generation part 38 transforms an image of an extracted area into a learning deformation image which is a predetermined number of vertical and horizontal pixels. A learning part 40 executes learning of a machine learning model 30 using output when the learning deformation image is inputted into the machine learning model 30.SELECTED DRAWING: Figure 2

    【課題】タイヤの画像に基づく当該タイヤの種類の推定精度を向上させることができるタイヤ種類学習装置、タイヤ種類推定装置、学習済モデルの生成方法、タイヤ種類推定方法及びプログラムを提供する。【解決手段】学習データ取得部34は、タイヤのトレッド面が写る学習画像を取得する。学習領域抽出部36は、学習画像からタイヤが写る部分に外接する領域を抽出する。学習変形画像生成部38は、抽出される領域の画像を所定の縦横画素数である学習変形画像に変形する。学習部40は、学習変形画像を機械学習モデル30に入力した際の出力を用いて、機械学習モデル30の学習を実行する。【選択図】図2
