CONVERSION METHOD TO THREE-DIMENSIONAL DATA FROM COMPLETION DRAWING OF BRIDGE
To provide a conversion method which can obtain three-dimensional data related to the latest state of a bridge easily and correctly from a completion drawing left as a micro-film.SOLUTION: A conversion method comprises the steps of: acquiring first digital image data and second digital image data from a first micro-film 20a recording a completion drawing of the new construction work and a second micro-film 20b recording a completion drawing of a repair section to record the digital image data in association with the structure name for each construction work; reading coordinate data from a linear drawing converted into digital image data to record the coordinate data in association with a panel point; forming the three-dimensional data of a bridge related to the new construction work; forming the three-dimensional data related to a repair work; and performing replacement processing of replacing an element corresponding to the three-dimensional data related to the repair work in the three-dimensional data related to the new construction work with the dimensional data related to the repair work.SELECTED DRAWING: Figure 1
【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最新の状態に係る３次元データを起こすことのできる変換方法を提供する。【解決手段】新設工事の竣工図が記録された第１のマイクロフィルム２０ａと改修部位の竣工図が記録された第２のマイクロフィルム２０ｂからそれぞれ第１のデジタル画像データと第２のデジタル画像データを取得して工事毎に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座標データを読み取り、格点と座標データとを関連付けて記録する工程と、新設工事に係る橋梁の３次元データを構成する工程と、改修工事に係る３次元データを構成する工程と、前記新設工事に係る３次元データにおいて前記改修工事に係る３次元データに対応する要素を前記改修工事に係る次元データに置き換える置換処理を行う工程と、を有することを特徴とする。【選択図】図１
