Time-of-flight (ToF) range imaging cameras perform full-field distance measurement, but require multiple frames to be captured sequentially in order to construct a single range image. When motion occurs during data acquisition, artifacts appear that limit the accuracy of range estimates. Analysis of these artifacts finds that they take the form of spatial waves whose frequency encodes motion information. We therefore propose a new technique for measuring motion in Time-of-Flight range imaging based on the continuous wavelet transform (CWT). Synchrosqueezing is explored as a means of improving the accuracy of velocity estimates.
