TIRE SURFACE SHAPE MEASURING DEVICE AND TIRE SURFACE SHAPE MEASURING METHOD

WIPO Patent Application WO/2012/144430

A1

The present invention detects the surface shape of each of tires having different sidewall surface thicknesses and tread surface widths with the same image resolution and high accuracy. This tire surface shape measuring device (1) captures an image of linear light applied to the surface of a tire (T), and measures the surface shape of the tire (T) on the basis of measurement signals extracted from the captured image of the linear light. The tire surface shape measuring device (1) is provided with an image capturing element (9) in which an image capturing surface for capturing the image of the linear light applied to the surface of the tire (T) is provided, an image capture area setting means (10) which sets an effective image capture area (A) provided with the length in the longitudinal direction of the image of the linear light on the image capturing surface such that all of the image formed on the image capture surface of the linear light is included, and a pixel data extracting means (11) which extracts a predetermined given number of measurement signals from the set effective image capture area (A).
