Abstract：
The invention provides a periodic graphic array extraction method. The method comprises the following steps of analyzing a layout file, and loading data of a graphic layer of the layout file; analyzing the spacing information of graphs of the graph layer, and extracting key parameters; clustering the graphs of the graph layer according to the key parameters to obtain N groups of graph arrays; screening a target graphic array from the N groups of graphic arrays; determining whether the target graphic array comprises a periodic graphic array or not; and if the target graphic array comprises a periodic graphic array, performing optical correction on the periodic graphic array. The invention further provides a computer device and a storage medium for realizing the periodic graphic array extraction method. The method is advantaged in that the calculation amount of optical correction of the flat layout can be effectively reduced.
