Abstract: Provided are a structured light projection module and a depth camera. The structured light projection module comprises: a light source array, comprising multiple sub-light sources arranged in the form of a two-dimensional pattern and used for transmitting array beams corresponding to the two-dimensional pattern; a lens for receiving and converging the array beams; and a diffractive optical element for receiving the array beams emitted after being converged by the lens and projecting structured light speckle pattern beams, wherein a structured light speckle pattern is formed through staggered superposition of at least two secondary structured light speckle patterns; each of the secondary structured light speckle patterns is formed by arranging multiple speckle blocks in a tiled manner; and each of the speckle blocks is composed of speckles, formed after at least several sub-light sources from among the multiple sub-light sources are diffracted by the diffractive optical element, of the same diffraction order. On the basis of ensuring the uniform distribution of structured light patterns, the solution improves the density distribution of structured light speckle patterns, and also has very high non-correlation.
