PROBLEM TO BE SOLVED: To provide an apparatus and method for analyzing a tire shape, capable of analyzing the shape with high accuracy even when the design pattern of an imaged image has a break.SOLUTION: An apparatus 4 for analyzing a tire shape comprises: a division line formation part 42 for forming a division line being a line within the region of a design pattern on the basis of an imaged image obtained by imaging a region including the design pattern formed on the surface of a tire; a design pattern region division part 43 for dividing the design pattern region of the imaged image on the basis of the formed division line; and an analysis part 44 for analyzing the divided design pattern regions to compose the analyzed results. The division line formation part 42 has the division line provided along a break when the design pattern includes the break and has one or more division lines when the design pattern does not include the break.SELECTED DRAWING: Figure 3

    【課題】撮影した画像の模様パターンに切れ目がある場合でも高い精度で形状を解析するタイヤ形状解析装置、タイヤ形状解析方法を提供する。【解決手段】タイヤ形状解析装置4は、タイヤ表面に形成された模様パターンを含む領域を撮影した撮影画像に基づいて模様パターンの領域内の線である分割線を生成する分割線生成部42と、生成した分割線に基づいて、撮影画像の模様パターンの領域を分割する模様パターン領域分割部43と、分割した模様パターンの領域をそれぞれ解析し、解析結果を合成する解析部44とを含み、分割線生成部42は、模様パターンが切れ目を含む場合、切れ目に沿って分割線を設け、模様パターンが切れ目を含まない場合、1つ以上の分割線を設ける。【選択図】図3
