Abstract
A tire 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.
Claims9
An apparatus for inspecting a tire, comprising:
- a plurality of image shooting means located at positions relatively displaced in a circumferential direction so as to shoot images of the circumferential surface of the tire and set for the respective shooting positions different from each other in an axial direction of the tire;
- a marker inserting means for entering markers in the images shot by all of the image shooting means at the same time when image shooting is being performed by all of the image shooting means while the tire is rotated circumferentially relative to the plurality of image shooting means;
- and
- an image synthesizing means for synthesizing the images shot by all of the image shooting means by shifting the markers in accordance with a relative displacements in the circumferential direction of the respective image shooting means.
