The present disclosure provides a VCSEL regular lattice-based laser speckle projector, comprising a VCSEL regular light-emitting lattice, a collimator, a diffractive optical element, an X-Y direction driving circuit, and a lattice display control module; multiple frames of different coded patterns are outputted by driving the light-emitting particles on the VCSEL regular light-emitting lattice to thereby implement a time-space labeling to the target object or projection space, and finally three-dimensional depth measurement of the target object is implemented through a depth decoding algorithm. Compared with the traditional structured-light space coding technology, the projector of the present disclosure facilitates implementation of time-space coding, such that a higher precision, robustness, and antijamming capability may be achieved during the process of depth decoding for the three-dimensional measurement.
