| 中文摘要: |
| 通过线激光及三角电荷耦合器件摄像技术对轮胎不圆度数据进行采集，并通过三角测距原理对数据进行计算，用特征图谱在二维上对三维不圆度数据进行直观显示，用傅里叶函数对测得的不圆度谐波数据进行分析，开发了谐波数据界面显示，满足了配套轮胎审核的要求，也对改进轮胎制作过程有指导作用。 |
| 英文摘要: |
| 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. |
