Resolving multipath interference in time-of-flight imaging via modulation frequency diversity and sparse regularization

Resolving multipath interference in time-of-flight imaging via modulation frequency diversity and sparse regularization

Time-of-flight (ToF) cameras calculate depth maps by reconstructing phase shifts of amplitude-modulated signals. For broad illumination of transparent objects, reflections from multiple scene points can illuminate a given pixel, giving rise to an erroneous depth map. We report here a sparsity-regula...
