Mixed reality (MR) technology is revolutionizing the construction industry by significantly enhancing building inspection and monitoring processes, leading to improved efficiency, accuracy, and safety.

Applications of MR in construction encompass effective building inspections, construction defect management, safety enhancements, and improved design collaboration.

By blending virtual and real-world elements, MR technology allows users to interact with digital information within their physical environment, thereby streamlining inspection and monitoring tasks.

Despite its advantages, the adoption of MR technology in construction faces challenges such as high costs, technological limitations, and a lack of technical skills among users.

The construction industry is also grappling with project complexity, low productivity, cost overruns, and safety issues, all of which MR technology aims to address.

Research indicates that MR enhances visualization, communication, and collaboration among stakeholders, providing real-time data that facilitates quick decision-making.

The proposed Robot Collaboration System (ROCOS) aims to create a digital twin environment, facilitating an iterative design process between designers and robots.

ROCOS operates in three stages: Layout, Design, and Assembly, ensuring seamless integration between virtual simulations and physical construction tasks.

Recent advancements include a new algorithm for extracting feature lines from building roof point clouds, which is crucial for accurate 3D building reconstruction.

Experimental validation of point cloud registration methods in semi-finished houses has demonstrated their feasibility and effectiveness in improving construction accuracy.

The future of alignment methods in MR may see a shift towards algorithmic approaches, potentially overshadowing traditional methods.
