    • Geometric errors vision inspection and error evaluation method of rudder structural parts

    • “针对接触式测量方法装夹定位后只能测量一种或两种参数、检测效率低等问题，有专家提出了一种创新的舵类结构件几何量误差和装配误差视觉检测方法。该研究通过计算机视觉系统获取舵轴和舵面区域图像，并利用图像预处理技术去除图像畸变和噪声。在边缘检测方面，研究团队对比了多种算子，最终选用Scharr算子提取舵轴图像边缘，Canny算子提取摇臂图像边缘，确保了边缘提取的清晰度和连续性。此外，该研究还采用霍夫直线和霍夫圆检测方法提取舵面边缘线特征、舵轴母线特征、摇臂圆轮廓特征，构建了几何量误差检测目标函数，并运用自适应遗传算法计算最优解。值得一提的是，该研究还结合了相机标定的内外参矩阵，实现了舵芯对称度、舵轴垂直度、摇臂夹角的快速检测。经过多次重复测量实验，对称度检测精度达到0.055 mm，垂直度检测精度达到0.225 mm，装配角度检测精度达到0.772°，完成单次检测耗时7 s。这一方法不仅提高了几何量误差检测精度和效率，还有助于推动舵类结构件成型、制造、在机检测的自动化和智能化水平提升。该研究成果为舵类结构件的质量控制和生产效率提升提供了新的解决方案，具有重要的工程应用价值和行业推广前景。”
