| Abstract: |
| The tire ellipticity data was collected by line laser and triangular charge-coupled device camera technology， and the data was calculated by the triangulation ranging principle. The three-dimensional ellipticity data was visually displayed in two dimensions with feature map， and the measured ellipticity harmonic data was analyzed by the Fourier function. The harmonic data interface display was developed，which not only met the requirements of tire audit， but also had a guiding role in improving the tire manufacturing process. |
