To provide a tire groove measuring device and a tire groove measuring method that can improve the accuracy in measuring the depth of a tire groove.SOLUTION: A tire groove measuring device 100 comprises: a camera 1; a facing calculation unit 63a as a calculation unit; and a determination unit 63b. The camera 1 has a light projection unit 2 that projects pattern light for measurement on the tire, and two imaging units 3 that are arranged in the same direction as a direction in which the tire groove extends. The facing calculation unit 63a calculates the facing relationship between an outer surface of the tire and the camera 1 based on the images photographed by the imaging units 3. The determination unit 63b determines whether the outer surface of the tire and the camera 1 face each other based on a result of calculation made by the facing calculation unit 63a.SELECTED DRAWING: Figure 3

    【課題】タイヤ溝の深さの計測精度を向上することができるタイヤ溝計測装置およびタイヤ溝計測方法を提供する。【解決手段】タイヤ溝計測装置100は、カメラ1、算出部としての正対算出部63aおよび判定部63bを備える。カメラ1は、タイヤに対して計測用の模様を投光する投光部2、およびタイヤ溝が延びる方向と同じ方向に並べられた2つの撮像部3を有する。正対算出部63aは、撮像部3によって撮影された映像に基づいてタイヤの外表面とカメラ1との正対関係を算出する。判定部63bは、正対算出部63aによる算出結果に基づいてタイヤの外表面とカメラ1が正対しているか否かを判定する。【選択図】図3
