摘要
This paper introduces a novel real-time high dynamic range 3D scanning method with RGB camera, which utilizes the cameras varying color sensitivity and the projector's dark time to alleviate saturation-induced measurement error. The varying color responses in R, G, and B channels creates three different intensity levels, and an additional capture at the projectors bright to dark transition state doubles the total intensity levels to six. Finally, saturation-induced errors can be alleviated by choosing the unsaturated pixel of best quality among the images with six intensity levels. Experimental results will be presented to demonstrate the success of such method.
