3D camera and light-emitting chip

The utility model discloses a 3D camera and a light-emitting chip, the 3D camera comprises a substrate, and a projection module, a light-emitting module and an imaging module which are arranged on the substrate, the projection module is used for emitting structured light image light beams; the light emitting module is used for emitting a floodlight beam, and a spectral curve of the floodlight beam comprises two wave crests after being subjected to Gaussian fitting disassembly; the imaging module is used for receiving the structured light image light beam and the floodlight light beam which are reflected by a target. The projection module and the light-emitting module cooperate to shoot the near-infrared light image of the target so as to carry out safety certification, the light-emitting module is set to emit the flood light beam with the Gaussian fitting disassembly curve comprising the two wave crests to serve as the supplementary light of the structured light, the light signal obliquely reflected by the ta
