Raster to vector conversion refers to scanning the paper - based engineering drawings into computer by using the technologies of computer graphics , computer image processing , pattern recognition , etc , and then transferring them into the vector files which can be used by cad software 光柵圖形矢量化技術就是利用計算機圖形學、計算機圖像處理、模式識別等技術,將原有的紙質工程圖紙,通過掃描輸入計算機,識別成計算機輔助設計軟件可以利用的矢量格式文件。
Concentrating on the technology of raster to vector conversion , the paper begins with an analysis of the process of raster to vector conversion , followed by the analysis , comparison , and realization of the algorithms in all stages of raster to vector conversion , including scanning , image binarizing , noise - reducing , separation of text from graphics , line vectoring , arc vectoring , as well as an improvement of several algorithms 本文對光柵圖形矢量化技術進行了探討,首先分析了光柵圖形矢量化的過程,然后分別對工程圖紙的掃描輸入、二值化、噪聲消除、圖文分離、直線矢量化、圓矢量化等各個階段的算法進行了分析、比較和實現(xiàn),并對部分算法進行了改進。
