摘要： An objective of the present invention is to subtract only the difference between bulge and dent mark heights and compute and acquire only the heights of bulges and dents even when bulges and dents are present so as to overlap in the bulge and dent marks. Provided is a tire shape inspection method for inspecting sidewall surface shape defects in inspection tires using an image of a sample tire having sidewall surfaces on which bulge and dent marks are formed. The 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 measuring unit (301) acquires measurement data for a plurality of lines by repeatedly executing, on a reference tire, a measurement process to acquire measurement data for one line. A first acquisition unit (311) generates height data for one line for each of the plurality of sets of measurement data measured by the measuring unit (301), arranges the generated plurality of values of one-dimensional height data into a matrix form, generates two-dimensional height data for the measured face, and generates reference shape data. A second acquisition unit (314) acquires object one-dimensional height data from one-line shape data measured by the measuring unit (301) for the object tire. The measuring method and measuring device are characterized in that a removal unit (315) compares the object one-dimensional height data and the one-dimensional height data of the reference shape data at the same position in the sub-scan direction for the object one-dimensional height data, and removes, from the object one-dimensional height data, the height component of the projection.

摘要： A position detection unit (302) detects the position of an optical cutting line, each time original image data of one horizontal line which intersects with the optical cutting line is input from an imaging section (103). An image synthesis unit (303) generates one-dimensional sequence data by arranging, in one dimension, the positions of the optical cutting line in each horizontal line detected by the position detection unit (302), and embeds the one-dimensional sequence data in the original image data to generate synthesized image data. A communication unit (304) transmits the synthesized image data generated by the image synthesis unit (303), to a processing device (105).

摘要： A first determination unit performs a process (first process) of sequentially dividing an intensity value constituting first data by a reference intensity value to calculate an intensity ratio and determining whether the intensity ratio exceeds a first threshold (steps S3 and S4). When a predetermined period has elapsed, a second determination unit calculates an average change rate of the first data in the predetermined period to determine whether the average change rate is within a predetermined range (steps S9 and S10). When it is determined that the average change rate is within the range, the reference intensity value is updated and lowered (step S11). When the reference intensity value is updated, the first determination unit performs the first process by using the updated reference intensity value in the next predetermined period.
