Abstract

The invention discloses a structured light and TOF technology fused 3D imaging device, comprising: a projection module (10) which comprises a light source (101), a collimating lens (102) and a diffractive optical element (103); the projection module (10) has a structured light emission mode and a TOF emission mode; in the structured light working mode, the projection module projects a structured light pattern to a target object; and in the TOF emission mode, the projection module projects a floodlight illumination pattern to the target object. The device further comprises a receiving module (20) which is used for collecting an optical signal emitted by the target object; and a control calculation module (30) which is used for controlling the projection module (10) and the receiving module (20) and calculating the depth information of the target object according to the optical signal acquired by the receiving module (20). According to the device, two working modes of structured light and TOF technology are fused, other component structures do not need to be added, the number of integrated components is reduced, the module size is reduced, the integration degree is effectively improved, and the application scene range of the device is greatly widened.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a method for integrating structured light and time-of-flight technology and a 3D imaging device. Background technique [0002] 3D imaging devices have begun to be used in some electronic consumer products in the market, such as motion recognition for somatosensory games, and structured light 3D face recognition for the new generation of iPhones. 3D imaging devices can greatly enrich user experience and enhance product competitiveness, especially 3D face recognition. Compared with 2D face recognition, due to the addition of one-dimensional information, the latter cannot be compared in terms of experience and security. comparable. Compared with traditional biometrics, such as fingerprint recognition, 3D face recognition is a step higher in reliability and security. [0003] Different from traditional 2D imaging devices, such as cameras, which can only obtain plane 2D info...
