Non-contact method and system for tire analysis
First Claim
1. A method for determining a condition of a tire having a rotational axis and a treaded surface disposed between two sidewalls, the method comprising the steps of:
- obtaining height information of a plurality points on the tire, wherein the plurality of points are selected from the treaded surface;
comparing height information of a designated portion of the plurality of points, with height information of at least one other portion of the plurality of points;
determining a condition of the tire based on a result of the comparing step; and
generating a result indicating the condition.

Abstract
A non-contact method and system for analyzing tire conditions. The system includes an emitter source for emitting radiation signals towards a tire having a treaded surface between two sidewalls. A detector is provided to receive signals reflected by the tire in response to the emitted radiation signals. A data processing system, coupled to the emitter source and the detector, obtains geometrical information, such as height, of a plurality points on the tire based on the signals received from the detector. The data processing system determines a condition of the tire by comparing geometrical information for a designated portion of the plurality points with other portion points on the tire. A color-coded surface profile showing a height distribution of the tire is also generated to assist diagnosis of the tire.
