HARD MEDIA RECORDS DIGITIZING AND RELATIVE DATA PROCESSING
摘要
Abstract
This paper introduce a practicable method to digitalize various curves or drawin gs recorded on hard- media such as paper. The AntoCAD software and a digitizing tablet are both necessary when digitize a curve or a drawing. The curve can be s eparated by a controllable acquiring - step into a series of short lines end to end and saved in a AntoCAD drawing database file automatically. Coordinates of t he end points of the separated lines can be read out from the file by running a special computer program developed by the author. Because the course of the curv e digitizing is based upon hypothenuse step, according rules of AutoCAD, not coo rdinate -step in normal data acquisition cases, it is generally necessary to con vert the hypotenuse-step-based data to normative coordinate-step-based ones thro ugh a special transforming calculation. This convenient and credible method woul d be very helpful for those people who need to get their various hard - copy cur ves or records processed and saved by means of computer.关键词
