Zusammenfassung:This paper presents an interpolation method for ToF depth sensor with pseudo 4-tap pixel architecture. Pseudo 4-tap pixel architecture uses different modulation signals for different row pixels. While faster data acquisition reduces motion artifacts, depth calculation with two vertical pixels lowers depth resolution. The proposed method uses offset values for similarity weights to improve depth resolution. Experimental results show that edge artifact is improved in the vertical direction.
