Pipeline models within walls and floors are constructed based on architectural drawings, combined with on-site environment capture and AR augmented reality technology to achieve perspective visualization of pipelines. Traditional pipeline detection methods, such as drilling detection, rely on historical drawings to probe and break walls, which have obvious limitations: low accuracy, damage to walls, and low efficiency. By applying AR augmented reality to overlay a virtual pipeline schematic onto real walls, construction efficiency is improved, pipelines are accurately located, safety is enhanced, accidents are avoided, and operations are standardized.
