自动光学检测系统采用周期性比较和逻辑运算的方法获取缺陷点的信息。但由于其最小周期比较Pitch存在小数
会造成比较对象的非正确选取。利用两点一线原理
可以构建一次线性方程使原来断点模拟成连续的点
达到无论比较距离是会否为整数
都能找到相对应的灰度值的效果。利用此方法可以提高异常点检出的准确度
同时会避免对产品产量、品质及成本的不利影响
具有重要意义。
Method for automatic optical inspection system with periodic comparison and logic operation can obtain defect point information. Because of the existence of minimal cycle comparison of Pitch decimal
we cannot get the correct comparison. The use of two points formed one line
we can construct a linear equation to simulate the original breakpoints into continuous points. Just then
whether the comparative distance is an integer
the corresponding effect is found in the gray value. Using this method to improve the accuracy of anomaly check
the adverse effect is avoided on the yield
quality and cost of the product
which has the vital significance.
