摘要：While the wheel (2) is attached to the vehicle (1) and while the vehicle (1) ismoving, the condition of the tire (5) on the wheel (2) is evaluated. As the vehicle (1)moves, the tire (5) rotates and moves in the longitudinal direction along the movementpath. While the tire (5) is rotating, the imaging device (3, 4) is used for a plurality ofdifferent portions (7) on the outer periphery of the tire (5) having a tread portion (10)separated by a tread gap (11). Import images. While the image is being captured, flashdevices (F1, F2, F3, F4) spaced in the longitudinal direction are activated to illuminate theouter peripheral portion (7) of the tire (5). The flash devices (F1, F2, F3, F4) are arrangedon one side of the movement path of the tire (5) and direct light at an acute angle withrespect to the movement path of the tire (5), so that the light is in the tread portion. Ashadow is projected on the tread gap (11) between (10). Each flash device (F1, F2, F3, F4)generates a series of flash lights when the flash device (F1, F2, F3, F4) is activated, andeach series of flash lights is a series of next flashes. Separated from the light at intervals.In the case of flash devices (F1, F2, F3, F4) that are activated at the same time andilluminate the overlapping part around the tire (5), each series of flash light is out of

phase, so one flash device (F1, F1, The flash light from F2, F3, F4) is emitted between theflash lights from the other or each other flash devices (F1, F2, F3, F4). The image isanalyzed by the data processor (8) to determine the extent of shadow in the tread gap(11) and provide an indication of the depth of the tread gap (11).
