| Abstract: | Based on the principle of uncertainty system with universal grey mathematics, an uncertainty system model USM1 to line-drawing data processing by CAD was put forward, and the means of precision inspection was introduced. The programming was compiled with Matlab 6 5 language. The results from two were compared with those from other grey models. With this model, the data needn't be preprocessed and the generations of accumulate plus and subtract needn't be made. The method can be used for model establishing on equal intervals, as well as on non-intervals, and has a high precision and is easy to use. |
