A METHOD AND APPARATUS FOR DE-NOISING DATA FROM A DISTANCE SENSING CAMERA |
摘要 |
It is inter alia disclosed to determine a phase difference between a light signal transmitted by a time of flight camera system and a reflected light signal received by at least one pixel sensor of an array of pixel sensors in an image sensor of the time of flight camera system, wherein the reflected light signal received by the at least one pixel sensor is reflected from an object illuminated by the transmitted light signal (301); determine an amplitude of the reflected light signal received by the at least one pixel sensor (301); combine the amplitude and phase difference for the at least one pixel sensor into a combined signal parameter for the at least one pixel sensor (307); and de-noise the combined signal parameter for the at least one pixel sensor by filtering with a filter the combined parameter for the at least one pixel sensor (309). |
