This article proposes a novel three-tap time of flight (ToF) modulation and demodulation scheme, which can effectively reduce the power consumption of multiple-phase data acquisition, transmission, and calculation for depth computing without losing ranging accuracy. Our three-tap rotation strategy also resolves the inconsistent gain and large residual distance calibration accuracy caused by CMOS technology. We also propose an inter-cluster pseudo-random coding design that effectively reduces the mutual interference among multiple ToF cameras working in the same scene. The proposed combination strategy can potentially advance the low-power miniaturization of ToF three-dimensional perception imaging technology.
