来自飞行时间相机的3D图像可能遭受由光散射引起的错误深度读数。为了减少这种散射伪影，提出了一种散射补偿方法。首先，散射进行了分析，并表示为一个复杂的图像的线性变换。然后，一个简单的散射模型制定。假设一个空间不变的点扩散函数作为散射模型，导致一个解的形式的反卷积计划，其计算的可行性和实用性，本文进一步讨论。
3D images from time-of-flight cameras may suffer from false depth readings caused by light scattering. In order to reduce such scattering artifacts, a scattering compensation procedure is proposed. First, scattering is analysed and expressed as a linear transform of a complex image. Then, a simple scattering model is formulated. Assuming a space invariant point spread function as a model for the scattering leads to a solution in a form of a deconvolution scheme whose computational feasibility and practical applicability are further discussed in this paper.
