Position-based augmented reality platform for aiding construction and inspection of offshore plants

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.
