Large Scale Calibration for Augmented Reality on Construction Sites

Abstract: Accurate calibration methods are a key to achieve accurate registration in AR systems. Most calibrations developed thus far represent the system accuracy as pixel errors regardless of the view distance. Examination of work tasks in construction, however, indicates that the system accuracy may not satisfy the accuracy demands of specific work tasks due to variations in the view distance. This indicates the necessity of large scale calibration for construction sites for seeing objects at longer ranges with satisfactory system accuracy. This paper proposes a new scheme for large scale AR calibration for construction sites.

Keywords: Augmented Reality, large scale calibration, construction
