Time-of-flight imaging of indoor scenes with scattering compensation

Mure-Dubois, James ; Hügli, Heinz

In: Proceedings. Conference Optical 3-D Measurement Techniques, 2007, p. 1-8

3D 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. Assuming a space invariant point spread function as a model for the scattering leads to a solution in a form of a deconvolution scheme.The improvemen tbrought by scattering compensation, as well as the...

    Summary
    3D 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. Assuming a space invariant point spread function as a model for the scattering leads to a solution in a form of a deconvolution scheme.The improvemen tbrought by scattering compensation, as well as the computational cost involved are further discussed in this paper.
