Abstract: A method for depth measurement with a time-of-flight camera using amplitude-modulated continuous light by acquiring for each of a plurality of pixels of a sensor array of the camera at least one sample sequence having at least four amplitude samples (A0, A1, A2, A3) at a sampling frequency higher than a modulation frequency of the amplitude-modulated continuous light. The method further includes: determining for each sample sequence of each pixel a confidence value (C) indicating a degree of correspondence of the amplitude samples (A0, A1, A2, A3) with a sinusoidal time evolution of the amplitude; and determining for each of a plurality of binning areas, each of which comprises a plurality of pixels, a binned depth value (Db) based on the amplitude samples (A0, A1, A2, A3) of sample sequence of pixels from the binning area, wherein the contribution of a sample sequence to the binned depth value (Db) depends on its confidence value (C).

Abstract: A method for corrected depth measurement with a time-of-flight camera using amplitude-modulated continuous light. In order to enable an accurate and efficient depth measurement with a time-of-flight camera, the method includes, for each of a plurality of pixels of a sensor array of the camera: acquiring with the camera a raw depth value rm for the pixel; and automatically calculating a ground truth value rt according to: rt=g(rm?cm)+ct, to correct a systematic depth error of the raw depth value rm, wherein cm is a pixel-dependent first offset, g is a pixel-independent first function and ct is a pixel-independent second offset.
