- Abstract
A real-time system based on three-dimensional marker to estimate the positions of the light source in reality scene is presented. And the real-time and highly credible shadow for augmented reality using a shadow algorithm is generated. In order to obtain accurate real-time lighting information, 2D ARToolKit marker is changed to 3D marker, eliminating the need for large number of pre-calculations of the previous algorithm, and then according to the obtained information of the light source, the real-time shadow is generated. The experiment results show that this system could detect the positions and number of the indoor light sources at a high rate of speed. And the generated real-time shadow is highly credible. The virtual lights and shadow estimated by this method can generate consistent effect in the real environment
