Abstract:
Due to their parallel illumination and acquisition for all the pixels, today's state-of-the-art time-of-flight (TOF) range cameras suffer from erroneous measurements caused by multiple reflections in the scene. The invention proposes to compensate for the multi-path fusing the results obtained by applying two spatially different illumination schemes, typically one to achieve highest possible lateral resolution and for the second one structuring the emitted light and by doing so lowering the lateral resolution but limiting the impact of multiple reflections.
