摘要： A shape measurement method for a tire includes: detecting an outer surface shape data and an inner surface shape of the tire from image data of the outer surface and the inner surface; subjecting irregularities along the tire circumferential direction around the tire in the outer surface shape data and in the inner surface shape data to Fourier transformation to take out primary waveform components respectively; adjusting the tire circumferential positions of both of the waveform components to adjust the tire circumferential positions thereof; adjusting the tire radial direction cross section positions of the outer surface shape data and the inner surface shape data from information about the placement angles and the positions of the first camera and the second camera; and synthesizing the outer surface shape data and the inner surface shape data based on the adjusted tire circumferential positions and the tire radial direction cross section positions.

摘要： A separation filter selection device provided with an image input unit, a memory unit, a setting unit, an evaluation unit and a separation filter selection unit is disclosed. The image input unit inputs a captured image capturing a tire surface including a characteristic portion thereof. The memory unit stores plural filters for performing image processing of the captured image, stores a training image in which the characteristic portion is separated from the captured image, and a weighted image in which a weighting is set to a predetermined region of the captured image. The setting unit combines two or more filters out of the plural filters and sets a separation filter. The evaluation unit derives an evaluation value of the separation filter on the basis of an image in which a differential between the processed image that has been processed by each of the filters of the separation filter, and the training image, and to which a weighting based on the weighted image is applied. The separation filter selection unit repeats the setting of the setting unit and the evaluation value computation of the evaluation unit until the evaluation value is within a specific range, and selects the separation filter corresponding to the evaluation value resulting from the repeated processing as a separation filter for separating the characteristic portion from the captured image.
