And a non-contact measurement method that analyzes and measures the image before and after deformation through image analysis using a camera and a camera.

그러나 종래 상기와 같은 타이어 형상변화 측정방식들은 측정시 기준 축과 타이어 간의 좌표계를 일치시키는 작업이 선행되어야 하는 번거로움과 이동이 용이하지 않은 문제점 등이 있었다.However, the conventional tire shape change measurement methods as described above have a problem that the operation of matching the coordinate system between the reference axis and the tire has to be preceded and the movement is not easy.

이에 본 발명은 상기와 같은 문제점을 감안하여 발명된 것으로, 중하중용 타이어의 형상 측정시 효율적으로 측정할 수 있으면서 초기에 선행되어야 하는 좌표축 설정없이 손쉽게 측정할 수 있는 차량에 장착된 타이어의 형상 이동식 측정장치를 제공함에 그 목적이 있다.Therefore, the present invention has been invented in view of the above-mentioned problems, and the shape-movable measurement of a tire mounted on a vehicle that can be measured efficiently without setting a coordinate axis to be measured at the beginning while efficiently measuring the shape of a heavy-load tire The object is to provide a device.
