摘要
高精度非接触在线视觉检测系统在当前工业生产中已有广泛应甩,但都是针对具体问题研制相应的系统,系统研制周期长、费用高.提出模块化的高精度非接触在线视觉检测系统,系统的硬件部分(照明系统、光学系统、探测器件、处理器和显示器)和软件部分(图像预处理、图像分割、边缘检测、边缘拟合和参数测量)均实现模块化.根据工业现场的实际测量要求,只需简单组合这些功能模块,即可完成系统的研制,系统开发周期短、费用低、该模块化高精度非接触在线视觉检测系统已成功应用于挠性接头、机床刀具等工件的在线检测,挠性接头测量不确定度优于1.4μm,刀头半径测量不确定度优于2.4μm.
High-precision non-contact online vision measurement system has been widely applied to industry production at present,but each system is developed just for specific measurement task leading to long development time and high cost.A modularized high-precision non-contact online vision measurement system is presented in this paper.Both the hardware and software of the system have been modularized.The hardware includes illumination, optical system,detector,processor and displayer,and the software includes image preprocessing,image segmentation, edge extraction,edge fitting and parameter measurement.An online measurement system can be developed by simply assembling these functional module according to the measurement request of industry production,which has short development time and low cost.The modularized high-precision non-contact online vision measurement system has been applied to the online measurement of flexible connector and machine tool,and measurement result shows that the uncertainty of tendon thickness of flexible connector is 1.4 μm and the uncertainty of radius of tool bit is 2.4 μm.
