摘要： A hand-held device for obtaining a three-dimensional topological surface profile of a tyre, the device comprising: a base comprising an aperture; a light source arranged in use to generate an elongate pattern of light, and to project said pattern through the aperture onto a rolling surface of the tyre; a detector arranged to image a region of the rolling surface of the tyre; a plurality of pairs of guide wheels mounted on respective axles mounted on the base, wherein the guide wheels on adjacent axles are linked by gears; and a rotary encoder arranged to generate a signal corresponding to rotation of an axle.

摘要： A method of obtaining a three-dimensional topological surface profile of a tyre using a device (100), the method comprising:
projecting an elongate pattern of light onto a surface of the tyre;
imaging, by a detector (130), at least of portion of the projected pattern reflected from the surface of the tyre;
using a rotary encoder (110) to determine relative movement between the device (100) and the tyre; and
using a wireless transceiver to communicate with an external device (400) to provide measurement data to the external device (400), wherein the measurement data comprises imaging data obtained by the detector (130) and signal data generated by the rotary encoder (110).
