摘要:
A depth-sensing method for a time-of-flight depth camera includes irradiating a subject with pulsed light of spatially alternating bright and dark features, and receiving the pulsed light reflected back from the subject onto an array of pixels. At each pixel of the array, a signal is presented that depends on distance from the depth camera to the subject locus imaged onto that pixel. In this method, the subject is mapped based on the signal from pixels that image subject loci directly irradiated by the bright features, while omitting or weighting negatively the signal from pixels that image subject loci under the dark features.
