摘要

抽样是计算机辅助检验计划的重要步骤。提出了一种利用触觉传感器进行相似断面表面检测的新颖采样方法。该方法将高斯曲率作为表面质量密度函数，通过划分表面质量相等的曲面来生成网格。然后应用在简洁表面检测采样中广泛应用的扩展Hammersley算法确定采样点的位置。在典型的相似截面表面上进行了仿真，验证了其效果。对叶轮叶片表面进行了实例试验。实验结果表明，在相同采样点数的情况下，与等参法相比，该方法具有更高的检测精度。

Sampling Method for Similar Section Surface Inspection

Sampling is a vital step in computer aided inspection planning. This paper proposes a novel sampling method for similar section surface inspection by using tactile sensor. The method considers Gaussian curvature as surface mass density function and generates grids by dividing surface with equal surface mass. Then extended Hammersley algorithm which is extensively used in concise surface inspection sampling is applied to determine the sample point location. Simulations on typical similar section surface are performed to validate its effect. A practical case on impeller blade surface is tested. The experimental result shows that the proposed method can achieve higher inspection precise compared equaparametric method with the same sample point number.
