Abstract: To ensure high-quality multi-projection display and fast projection scattering compensation processing, we propose a novel inter-reflection compensation algorithm for an immersive multi-projection system. Firstly, manual adjustment of projector image content can be a complex task. Therefore, we propose a multi-projection distortion correction method using color-structured light coding, which establishes a geometric mapping relationship between the projector and the display screen. This mapping relationship is then utilized to correct the distortion of the projection display screen. Secondly, the luminescence scattering between adjacent projection screens can result in color and brightness discrepancies. To address this issue, we propose a luminescence cross-scatter compensation algorithm for immersive multi-projection systems. Furthermore, through experiments, we demonstrate the effectiveness of our approach in compensating for inter-reflection. Our results indicate that our method effectively mitigates light scattering and achieves high levels of visual fidelity and resolution. [ABSTRACT FROM AUTHOR]
