Abstract
A method of calibrating a direct time-of-flight (dToF) sensor to compensate for crosstalk includes emitting N photonic pulses from an emitter of the dToF sensor where N is the number of photonic pulses, receiving N crosstalk signals including a first crosstalk signal and N−1 remaining crosstalk signals at a receiver of the dToF sensor, averaging the N−1 remaining crosstalk signals to generate an averaged crosstalk signal, subtracting the first crosstalk signal from the averaged crosstalk signal to generate an estimated wraparound signal, subtracting the estimated wraparound signal from each of the N−1 remaining crosstalk signals to obtain corrected crosstalk signals, and calibrating the dToF sensor using the corrected crosstalk signals.
