摘要： A inspection apparatus arranged with a plurality of cameras located at relatively displaced circumferential positions and set for the respective shooting positions different from each other in the axial direction of the tire. Thus the images of the inner circumferential surface of the tire are shot by the plurality of cameras as the tire is rotated circumferentially relative to the plurality of cameras. During this operation, markers are inserted at the same time in the images shot by all of the cameras. The images are synthesized using these markers as reference positions in aligning the shot images in accordance with the relative displacements of the cameras in the circumferential direction.

摘要： There are provided an inspection method of tire uneven marks capable of judging defect of three-dimensional form of the mark in a higher reliability without depending on a brightness distribution image of unevenness, and an inspection apparatus of tire uneven marks. The inspection method of tire uneven marks comprises a step of measuring heights of unevenness inclusive of marks to be inspected with respect to each area element in a predetermined tire surface region to acquire unevenness distribution data, a step of specifying a tire surface portion corresponding to a mark model in the tire surface region from data of three-dimensional form of a mark model previously prepared as a template of the each mark and the above acquired unevenness distribution data, and a step of determining a coincidence between the unevenness distribution data of the specified tire surface portion with respect to the each mark and data of three-dimensional form of the mark model to judge an acceptance of the three-dimensional form of the mark based on the coincidence.

摘要： A tire inspection device generates an analyzing wavelet for wavelet transformation correlating time, corresponding to tire surface position, and frequency, based on a frequency representing a characteristic portion of a predetermined tire surface structure. After this, the tire inspection device generates and stores an integer numeric filter from the created analyzing wavelet, detects the tire surface structure, carries out wavelet transformation on a signal obtained by the detection by using the numeric filter as the analyzing wavelet, and outputs the transformation result as the characteristic information representing the characteristic portion.

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.
