| 中文摘要: |
| 以Matlab为开发平台、Sobel算子理论为基础，设计程序辨识并提取PGM图中的单个节距花纹信息，根据输入参数，结合轮胎整周PGM花纹图自身的特点，自动生成并优化轮胎整周PGM花纹图。与UG软件中二次开发的扫描程序生成的PGM图相比，该程序最终生成的轮胎整周PGM花纹图的噪声仿真误差在1%以内，效率提升10倍以上。 |
| 英文摘要: |
| Based on Matlab platform and Sobel operator theory，a program was designed to identify and extract the single pitch pattern information in the PGM diagram.According to the input parameters，combined with the characteristics of the tire whole-cycle PGM pattern，the tire whole-cycle PGM pattern was automatically generated and optimized.Compared with the PGM diagram generated by the scanning program developed in UG software，the noise simulation error of the PGM diagram generated by the program was less than 1%，and the efficiency was increased by more than 10 times. |
