量測程式自動生成技術

本文提出一套由工程圖自動生成三次元量測程式之技術。系統先以工程圖標註物件偵測技術定位尺 寸、幾何公差框與基準符號，再透過視覺語言模型解析工程語意，建立結構化標註資料。其後，整合幾 何特徵映射、跨視圖關聯、基準座標系推論及幾何尺寸與公差判讀規則，建立圖面標註與孔、平面、軸 線、距離及位置度等量測項目之對應關係，並依量測知識庫規劃探針方向、量測順序、測點配置、量測 路徑及安全檢核，最終產生可供三次元量測儀執行之量測程式。此技術可降低人工判讀與程式建置負擔， 提升量測流程之一致性、可靠性、可追溯性與整體作業效率。

This article proposes an automatic generation technology for coordinate measurement machine (CMM) measurement programs from engineering drawings. The proposed approach first applies image-based annotation detection to identify the positions of dimensions, geometric tolerance frames, and datum symbols. A vision-language model is then used to interpret the engineering semantics of these annotations and convert them into structured annotation data. The system further integrates feature mapping, cross-view correlation analysis, datum coordinate system inference, and geometric dimensioning and tolerancing (GD&T) interpretation rules to transform drawing annotations into measurable items, such as holes, planes, axes, distances, and position tolerances. Based on a measurement knowledge base, the system plans probe directions, measurement sequences, point distribution, and safety checking procedures, and finally outputs measurement programs executable on coordinate measuring machines. This technology can reduce the workload of manual drawing interpretation and improve the consistency and traceability of the conversion process from engineering drawings to measurement programs.
