摘要： A method of determining relief markings on a tire's sidewall surface includes assigning, to each pixel of a three-dimensional image of the surface, a grey-level value proportional to an elevation point corresponding to the pixel, to obtain a starting image. Using linear structuring elements of successively increasing sizes and oriented circumferentially, a series of successive morphological openings is performed iteratively on the starting surface. An image value obtained after a morphological opening using a structuring element is subtracted from an image value obtained after a morphological opening using a structuring element of an immediately lower size, to obtain a succession of images flattened by differencing. A thresholding operation is performed on the images flattened by differencing, to obtain binary images. A set-theoretic union of values of each of the binary images is performed, to obtain a final binary image in which markings appear in relief.

摘要： A method of determining relief elements on a tire 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 (ƒ). The method also includes transforming the starting image (ƒ) by a first top-hat operation, with aid of a first structuring element, so as to obtain an image (ƒ1) flattened by differencing, (ƒ1=ƒ—γ3,150(ƒ)). The method further includes performing a thresholding operation on the image flattened by differencing, so as to obtain a segmented image, (T (ƒ1)=seg1) in which relief elements appear white on a black background.
