| contents | The growing prevalence of intelligent manufacturing and autonomous vehicles has intensified the demand for three-dimensional (3D) reconstruction under complex reflection and transmission conditions. Traditional structured light techniques rely on inherent point-to-point triangulation, which limits accurate 3D measurements in these challenging scenarios. Parallel single-pixel imaging (PSI) has demonstrated unprecedented superiority under extreme conditions and has emerged as a promising approach of accurate 3D measurements. However, a complete theoretical model has not been reported in existing work to well explain its underlying mechanisms and quantitatively characterize its performance. In this study, a comprehensive theoretical model for the PSI method is proposed, including imaging and noise models. The proposed imaging model describes light transport coefficients under complex illumination, elucidating the intrinsic mechanisms of successful 3D imaging using PSI. The developed noise model quantitatively analyzes the impact of environmental noise on measurement accuracy, offering a framework to guide the error analysis of a PSI system. Numerical simulations and experimental results validate the proposed models, revealing the generality and robustness of PSI. Finally, potential research directions are highlighted to guide and inspire future investigations. The established theoretical models lay a solid foundation of PSI and brings new insights and opportunities for future application in more demanding 3D reconstruction tasks. |
