基于光照复用的变光照采集系统设计与控制

The Design and Control of Relighting System Based on Multiplexed Illumination

针对当前变光照采集系统的局限和不足,设计了一种光源密集分布的大范围全景变光照采集系统,可对多个运动目标进行密集光照采集。为解决单一光源成像时曝光不足、信噪比低的问题,提出一种基于光照复用的变光照采集控制策略,并通过解复用估计出采集对象在单一光照下表面反射属场的图像表示。模拟实验结果验证了所提方法的可行性,真实光照场景实验结果给出了所提方法的估计效果。通过比较分析单一光源成像和解光照复用估计结果,表明所提方法具有更好的性能和更高的信噪比。

After introducing the deficiencies and problems of several existing 3 D capture and relighting systems（CRS）, this paper designed a relighting system which has sufficient light number and is large enough to provide multi-objective light research .In order to solve the single source underexposure when imaging and the problem of low SNR , a variable illumination acquisition control strategy based on illumination reuse has been used .The single light source images can be obtained by de-multiplexing the multiplexed illumination images .Furthermore , simulation results have verified the feasibility of the proposed method , and the real light scene experiment result shows the estimated effect of the proposed method .Through the comparative analysis of the single light source imaging and illumination reuse estimation , results show that the proposed method has better performance and higher signal-to-noise ratio .
