摘 要:本文基于AR(增強現實)空間測量方法,通過對現實世界真實物體圖像信息進行實時計算,虛擬構造三維空間系統,完成非接觸式空間尺寸測量。并在現實世界真實場景適當的位置疊加顯示適當的虛擬信息,將數字標尺信息與周圍的環境融合。這種AR(增強現實)空間測量方法,不需要接觸物體即可測量物體的空間位置,并與三維設計BIM數據進行實時比較,將誤差點實時反饋給竣工驗收人員。達到節省大量的人工測量,保證驗收質量,提高變電工程驗收智能化水平的目的。

Abstract:Based on an AR (augmented reality) space measurement method,the real-time calculation of real-world object image information,virtual construction of three-dimensional space system,the completion of non-contact space size measurement. And in the real world scene appropriate location overlay display appropriate virtual information,the digital ruler information and the surrounding environment integration. This AR space measurement method can measure the spatial position of the object without touching the object. Compared with the 3D design BIM data,the error points are fed back to the completion acceptance personnel in real time. It can save a lot of manual measurement,ensure the quality of acceptance,and improve the intelligent level of acceptance of substation engineering.
Keywords:augmented reality;space measurement;substation engineering;completion acceptance
0 引 言
增強現實(Augmented Reality,簡稱AR)[1],是指透過攝影機影像的位置及角度精算并加上圖像分析技術,讓虛擬世界與現實世界進行互動的技術。增強現實的三大特點:三維注冊、實時交互和虛實融合。
建筑信息化模型簡稱BIM,是一個完備的信息模型,通過三維技術對變電站工程進行設計[2],BIM設計的意圖,在變電工程建造完成后需要在進行逐項核查。將BIM變電站BIM三維模型作為工程驗收基準數據,并借助AR空間測量技術將變電站實物與變電站三維設計方案融合,實現變電站實物與工程設計方案的精準核對,提高變電工程驗收智能化水平。
1 背景介紹
變電站施工建造,分為階段性驗收和整體工程驗收。驗收過程中需對實際建筑物及變電站設備進行安裝尺寸及位置的測量。由于變電站系統設備多,室內外空間結構復雜,人工測量耗人力。……
