| Summary: | The illumination coherence in augmented reality is an important means that makes virtual objects get realistic. It can make the computergenerated virtual objects blend into the real scene In order to archieve the illumination coherence of augmented reality, this paper modifies the present algorithm and proposes a algorithm based on single tag This new method collects the brightness of the identification marking in any direction to make sure which direction the light source might be; it compares the brightness of the identification marking with the brightness of the virtual objects to ensure the brightness of the light source; it determines the color of the light source by getting the color of the marker portion of no inkjet Experiments show that in meet the realtime and stability at the same time,the average angle between the virtual light source which is estimated by using the algorithm in this paper and the true source is 43 degrees,and the virtual objects can correctly cast shadows |
