摘要： An apparatus for acquiring images of an interior surface of a tire includes at least one image acquisition module. Each image acquisition module is provided with a lighting source, an image acquisition device, and a reflector. The lighting source is arranged to project a beam of light onto a predetermined zone of the interior surface of the tire. The image acquisition device is arranged to acquire a reflected beam of light, which corresponds to light from the beam of light from the lighting source that is reflected off the predetermined zone of the tire. The reflector is positioned optically between the lighting source and the predetermined zone of the tire. Each image acquisition module may be provided with a plurality of lighting sources, image acquisition devices, and reflectors.

摘要： A candidate extraction unit (322) executes candidate extraction processing wherein a fixed number of consecutive height data items are extracted from one line of height data using a certain sample point as the starting point, the median for the extracted height data items and the difference therefrom for each extracted height data item are calculated, and sample points with a difference that is at least a height threshold are extracted as singular point candidates. An interpolation unit (323) determines, to be a singular point, a singular point candidate having a number of consecutive repetitions that is less than a width threshold, deletes the height data for the determined singular point, interpolates the deleted height data using height data for sample points which are adjacent to and other than such singular point, and generates shape data for evaluating runout and bulge/dent.

摘要： A tire shape inspection method executes the following steps: first, as a teaching operation step, boundary lines of the bulge and dent marks are detected in a sample source image of a sample tire, a mask image is generated which denotes the boundary lines, regions are removed from the sample source image which correspond to the boundary lines which are denoted in the mask image, and a height offset image is generated which represents the heights of the remaining regions with one or more offset values. Next, as an inspection operation step, the height offset image is subtracted from an inspection image of the inspection tire, the boundary regions which the mask image represents are removed, and, on the basis of the obtained bulge/dent removal image, shape defects of the sidewall surfaces of the inspection tire are inspected.

摘要： A method of determining relief elements on a tyre surface includes capturing a three-dimensional image of the surface and assigning to each pixel (i, j) of the image a grey-level value proportional to a topographic elevation of a point corresponding to the pixel, so as to obtain a starting image (f). The method also includes transforming the starting image (f) by a first top-hat operation, with aid of a first structuring element, so as to obtain an image (f1) flattened by differencing, (f1=f−γ31,150(f)). The method further includes performing a thresholding operation on the image flattened by differencing, so as to obtain a segmented image, (T (f1)=seg1) in which relief elements appear white on a black background.
