Assessing the effectiveness of utilizing low-cost inertial measurement unit sensors for producing as-built plans

As-built mapping using terrestrial sensors is crucial for accurately documenting the final state of building structures. However, conventional methods often face limitations in urban environments, such as obstructions and the need for clear sightlines. This study evaluates the effectiveness of the low-cost Moasure ONE Inertial Measurement Unit sensor for producing as-built plans, addressing challenges associated with traditional surveying methods like total stations. The research investigates the Moasure ONE's capabilities in terms of cost, time efficiency, flexibility, and productivity, while adhering to the USA Federal Geographic Data Committee and American Society for Photogrammetry and Remote Sensing accuracy standards. The methodology includes a statistical study, data manipulation, georeferencing, and quality assessment using ground control points. Results indicate that Moasure ONE can achieve a horizontal positional accuracy (RMSEH1) of 17.7 cm, aligning with the required tolerances for detailed mapping. The findings suggest that Moasure ONE offers significant advantages over traditional methods, including reduced survey time and increased detail capture, making it a viable alternative for professional surveying tasks in construction and engineering projects.
