We propose an augmented reality platform to help workers with fabrication and inspection of offshore structures. The platform is designed to work under various constraints that are commonly encountered in an industrial environment and often make the existing AR methods fail to work properly. It consists of modules for tracking, registration, and augmentation. The tracking module estimates the worker’s position in real time. The registration module aligns the actual objects with 3D computer-aided design models to estimate an accurate pose of the worker’s mobile device. The augmentation module correctly augments information on the target objects on the device screen using the pose data. We test several application scenarios to demonstrate the feasibility of the proposed platform for the fabrication and inspection processes of an offshore plant.

用于辅助海上工厂建设和检查的基于位置的增强现实平台

我们提出了一个增强现实平台，以帮助工人制造和检查海上结构。该平台旨在在工业环境中常见的各种约束下工作，并且经常使现有的 AR 方法无法正常工作。它由用于跟踪、注册和增强的模块组成。跟踪模块实时估计工人的位置。注册模块将实际物体与 3D 计算机辅助设计模型对齐，以估计工人移动设备的准确姿势。增强模块使用姿势数据正确增强设备屏幕上目标对象的信息。我们测试了几个应用场景，以证明所提议的平台在海上工厂的制造和检查过程中的可行性。
