Abstract
A method for multipath error compensation comprises an unstructured light source () illuminating a scene during a plurality of consecutive time frames. A structured light source () illuminates the scene concurrently, the illumination by the structured source () occurring during predetermined frames of the plurality of consecutive time frames. An array of photodetectors () each generate a set of signals in response to irradiation with light reflected from the scene according to an indirect time of flight calculation technique to yield a plurality of sets of signals. An error estimate is derived () from the plurality of sets of signals generated during a selected time frame of the plurality of consecutive time frames when structured illumination takes place and another time frame temporally about the selected time frame when both structured and unstructured illumination takes place. The error estimate is applied in a range calculation with respect to the scene.
