中文摘要: |
在总结印痕分析方法的基础上对轮胎静负荷印痕轮廓的提取和筛选方法进行改进,以提升轮胎静负荷印痕数据分析的准确性。通过对轮胎静负荷印痕图像噪声因素处理、二值化阈值选择以及轮廓提取后对轮胎静负荷印痕接地轮廓边界点集进行重构和使用Alpha-shape算法对轮胎静负荷印痕整体外轮廓形状进行重构等,将轮胎静负荷印痕长度分析值与实测值的相关因数从0.81提高至0.99。 |
英文摘要: |
Based on the summary of imprint analysis methods,the extraction and screening methods of static load imprint contours were improved in order to improve the accuracy of tire static load imprint data analysis. By processing noise factors in tire static load imprint images,selecting binarization thresholds,and reconstructing the boundary point set of tire static load imprint grounding contours after contour extraction,and using the Alpha-shape algorithm to reconstruct the overall outer contour shape of static load imprints,etc,the correlation factor between tire static load imprint length analysis value and the measured value was increased from 0.81 to above 0.99. |
