目的:为了实现对微小尺寸零件复杂边缘的识别,根据微小尺寸零件加工特性,提出一种微小尺寸零件复杂边缘显微图像识别算法。方法:该算法通过对不同工件的边缘过渡区进行提取,建立不同工件边缘过渡区的数学模型,再从数学模型中根据加工特性确定边缘点精确位置。结果:实验结果表明:精研磨工艺的零级1mm标准量块的测量误差为0.395μm。结论:通过对精研磨、冲压、线切割三种常见微细加工方法建模分析得出:加工特性对微小型结构件边缘区域影响较大,边缘精确识别时应考虑加工特性的影响。该算法思想上考虑了实际加工特性的影响,算法上加入统计学方法,通过建立过渡区数学模型使边缘检测结果达到亚象素级。 相似文献

模态分析的动画显示技术给结构动态特性的分析评价提供了有效的参考。目前,国外是采用专门的模态分析仪来实现这项技术。本文则介绍利用微计算机进行模态分析中,如何在微机上实现结构复模态振型的动画显示。文中推导了结构复模态振型的表达式,论述了结构图形与显示幕图形的坐标变换,并给出了在APPLE-Ⅱ微机上实现二维和三维结构动画图的实例。 相似文献
