Abstract
The specification provides a depth imaging method and device and a computer-readable storage medium. The method includes: controlling an emission module comprising a light emitting device to emit at least two speckle patterns that change temporally to a target object; controlling an acquisition module comprising a light sensor to acquire reflected speckle patterns of the at least two speckle patterns reflected by the target object; and performing spatial-temporal stereo matching by using the reflected speckle patterns and the at least two reference speckle patterns, to calculate offsets of pixel points between speckles of the at least two reference speckle patterns and speckles of the reflected speckle patterns, and calculating depth values of the pixel points according to the offsets.
