机器视觉自动检测系统的稳定性将直接影响产品检测的质量。本文根据随机过程的理论,利 用SAS软件对研究开发的集成用路芯片管脚尺寸检测系统的工作状态进行了分析测试。测试 结果表明,整个系统的测量结果是一个具有各态历经性的平稳随机过程,因此,我们利用一段 样本值就能估计整个过程的均值和标准差,从而获得整个过程的性质。 The stability of the machine vision automatic inspection system will directly affect the quality of product inspection. In this paper, according to the theory of stochastic process, SAS software is used to analyze and test the working status of integrated chip size detection system. The test results show that the measurement of the whole system is a stationary and stochastic process with various ergodicity. Therefore, we can estimate the mean and standard deviation of the whole process by using a sample of samples to obtain the whole process.
