Abstract

This research presents the photometric registration of a 3-Dimensional Computer Graphics (3DCG) and live video image at the time of simulating lighting design in Augmented Reality (AR). First, a color chart system with three brightness levels and a brightness measurement system were developed. Secondly, the accuracy of the 3DCG model with illumination effects was verified. Finally, the 3DCG model with illumination effects was input to an AR system in which a color chart system was installed. Consequently, the brightness of the 3DCG model and the live video image were equalized. This experiment showed that the proposed system was effective.
