CONVERSION METHOD AND CONVERSION SYSTEM FOR CONVERSION OF BRIDGE COMPLETION DRAWING INTO 3D DATA
To provide a conversion method that easily and accurately generates 3D data of a bridge from a completion drawing left on a microfilm.SOLUTION: A conversion system comprises: a step of acquiring digital image data, by reading a microfilm on which a completion drawing is recorded by reading means, and recording the digital image data in association with a structure name; a step of detecting a grade from the line drawing converted into digital image data, reading the coordinate data written on the grade, and recording these in association with each other; a step of giving the coordinate data for each detected grade and projecting this on a spatial coordinate system; and a step of arranging a line connecting the grades whose coordinate data are adjacent positions in the spatial coordinate system.SELECTED DRAWING: Figure 5
【課題】マイクロフィルムで残された竣工図から、容易かつ正確に橋梁の３次元データを起こす変換方法。【解決手段】竣工図が記録されたマイクロフィルムを読取手段で読み取ることでデジタル画像データを取得し、当該デジタル画像データを構造名に関連付けて記録する工程と、デジタル画像データ化された線形図から格点を検出すると共に、格点に記された座標データを読み取り、これらを関連付けて記録する工程と、検出した格点毎に前記座標データを与えて空間座標系に投影する工程と、座標データが隣接位置となる格点同士を結ぶラインを空間座標系に配置する工程と、を有することを特徴とする。【選択図】図５
