    摘要： A moving vector calculation unit calculates a moving vector M representing a quantity and a direction of movement of a probe on basis of a stylus displacement vector, a stylus displacement vector D, and a direction change angle θ of the stylus displacement vector D that is caused by a frictional force between a stylus 32 and the measuring surface 5a during scanning of the measuring surface 5a by the stylus 32. The stylus displacement vector D is a vector including a quantity and a direction of position displacement of the stylus 32 relative to the probe 5. Movement of an XY-stage 7 is controlled so that the probe 6 moves in accordance with the moving vector M.

    摘要： The temperature of the tread surface part of a tire is increased by running the tire in contact with a drum. The increase in the temperature of the tread surface part is due to the heat of friction between the tread surface part and the drum. Because large increases in temperature indicate that the friction is causing a large amount of wear, it is possible to forecast with ease the amount of wear of the tire from the increase in temperature of the tread surface part. The temperature of the tread surface part can be measured using a thermography machine, and the wear in the tread can be determined by looking at an image that shows the temperature.
