基于增强现实的灌浆协同决策可视化研究北大核心CSCD

灌浆工程具有隐蔽性、专业性等特点,为提升灌浆质量,需要采用会商等手段进行灌浆协同决策。然而当前会商采用二维图纸或三维虚拟场景进行协同分析,缺乏物体纵深距离的真实空间维度,存在沉浸式交互不佳且决策信息共享不及时等问题。针对上述问题,本文提出基于增强现实的灌浆协同决策可视化方法,基于灌浆三维信息模型,以视觉惯性里程计技术为基础,实现虚拟模型与真实场景的融合与沉浸式交互分析;采用基于云端通信的状态同步法、锚点转移法和Vuforia增强图像识别技术,实现灌浆协同决策信息的三维沉浸式可视化共享。工程实例分析结果表明,本文提出的方法能够实现灌浆决策信息的沉浸式交互查询与跨区域协同决策,为灌浆过程控制提供了新思路。

Study on visualization of grouting collaborative decision based on augmented reality

Grouting projects are characterized by concealment and professionalism. To improve grouting quality, consultation and other methods are often adopted for grouting collaborative decision-making. However, the current consultation approach uses 2D drawings or 3D virtual scenes for collaborative analysis and lacks the real spatial dimension for the depth distance of objects, thus suffering poor immersed interaction and untimely decision information sharing. To solve these problems, this paper develops a visualization method for grouting collaborative decision-making by applying augmented reality technology. Based on the grouting 3D information model and visual inertial odometer technology, a fusion of virtual models and real scenes together with immersive interactive analysis is realized. We realize 3D immersive visual sharing of grouting collaborative decision information via adopting a state synchronization method based on cloud communication, the anchor point transfer method, and the enhanced image recognition technology of Vuforia. The results of engineering case analysis show our method can realize immersive interactive query about grouting decision information and cross-regional collaborative decision, proving a new effective approach to grouting control.
