1. A time-of-flight camera, comprising:
a time-of-flight depth image sensor;
a logic machine;
a communication subsystem; and
a storage machine holding instructions executable by the logic machine to:
process time-of-flight image data acquired by the time-of-flight depth image sensor by, prior to denoising, performing phase unwrapping pixel-wise on the time-of-flight image data to obtain coarse depth image data comprising depth values; and
send the coarse depth image data and the active brightness image data to a remote computing system via the communication subsystem for denoising.
