Abstract

The invention discloses an infrared 3D detection transmitting terminal module and a depth camera, and relates to the technical field of optics and electronics. The infrared 3D detection transmitting terminal module comprises at least two light source groups, and a collimating mirror and a beam shaper which are sequentially arranged along the light emitting direction of the light source groups, the collimating mirror is divided into at least two first optical areas, and each light source group corresponds to one first optical area; the light source groups are used for emitting light beams towards the corresponding first optical areas; the collimating lens collimates and deflects the light beams through the first optical area so as to emit parallel light beams at a preset angle; and the light beam shaper is used for shaping the light beam emitted from the first optical area and projecting the shaped light beam to the object to be measured. According to the infrared 3D detection transmitting terminal module, the integration level of the infrared 3D detection transmitting terminal module can be improved, and the overall size of the infrared 3D detection transmitting terminal module is further reduced.

Description

technical field [0001] The invention relates to the technical fields of optics and electronics, in particular to an infrared 3D detection transmitter module and a depth camera. Background technique [0002] 3D imaging technology is the core of the new generation of human-computer interaction technology. In addition to the 2D imaging capability of the target object, it can also obtain the depth information of the target object. According to the depth information, 3D scanning, scene modeling, gesture interaction, etc. can be further realized. Features. With the rigid demand of mobile terminal equipment for 3D imaging technology, depth cameras will be widely used in mobile terminal equipment. [0003] Among them, the infrared 3D detection transmitter module is based on the core equipment in the structured light depth camera. It mainly emits multiple beams of planar light with different directions after collimating the beam emitted by the light source group, and then cooperates...
