Active illumination 3D imaging systems based on Time-of-flight (TOF) and Structured Light (SL) projection are in rapid development, and are constantly finding new areas of application. In this paper, we present a theoretical design tool that allows prediction of 3D imaging precision. Theoretical expressions are developed for both TOF and SL imaging systems. The expressions contain only physically measurable parameters and no fitting parameters. We perform 3D measurements with both TOF and SL imaging systems, showing excellent agreement between theoretical and measured distance precision. The theoretical framework can be a powerful 3D imaging design tool, as it allows for prediction of 3D measurement precision already in the design phase.
基于飞行时间（TOF）和结构光（SL）投影的主动照明3D成像系统正在迅速发展，并不断发现新的应用领域。在本文中，我们提出了一种理论设计工具，可用于预测3D成像精度。针对TOF和SL成像系统推导了理论表达式。这些表达式仅包含物理上可测量的参数，而不包含拟合参数。我们使用TOF和SL成像系统进行了3D测量，结果表明理论距离精度与测量值之间具有出色的一致性。该理论框架可以成为一个强大的3D成像设计工具，因为它允许在设计阶段就预测3D测量精度。
