A tire shape measuring system measures a surface shape on the basis of an image of a line of light (a light section line) emitted to a surface of a relatively rotating tire using a light-section method. The shape measuring system includes a light projector for emitting a plurality of lines of light onto a tire surface in directions different from a direction in which the height of the surface is detected so as to form a plurality of separate light section lines and a camera for capturing images of the light section lines in directions in which chief rays of the lines of light are specularly reflected by the tire surface. The shape measuring system individually detects the coordinates of the light section lines from images of pre-defined independent image processing target areas for each captured image and calculates the distribution of the surface height using the detected coordinates.

A tire shape measuring system measures a surface shape on the basis of an image of a line of light (a light section line) emitted to a surface of a relatively rotating tire using a light-section method. The shape measuring system includes a light projector (10) for emitting a plurality of lines of light onto a tire surface in directions different from a direction in which the height of the surface is detected so as to form a plurality of separate light section lines and a camera (20) for capturing images of the light section lines in directions in which chief rays of the lines of light are specularly reflected by the tire surface. The shape measuring system individually detects the coordinates of the light section lines from images of pre-defined independent image processing target areas for each captured image and calculates the distribution of the surface height using the detected coordinates. Thereby, clear images of light section lines can be obtained at high image of the light section lines capturing speed without reinforcing the strength of lines of light, and calculating load of image processing needed by light section lines detection is reduced.

Disclosed is a tire shape inspection method that can reliably and without misidentification perform accurate shape defect inspection in a short period of time by excluding measurement values in a range in which embossed marks are formed from distribution information for surface height measurement values on the sidewall surface of a tire. In the method, a processor automatically detects the positions of the embossed marks based on sample surface shape information obtained from a sample of the tire, and automatically sets coordinate information for a mask range surrounding the area where said marks are present (S2-S15).
