Abstract

The present invention relates to the field of optical technology, and provides a depth camera and a protection method for the depth camera. The depth camera includes a projection module, an imaging module, and a monitoring module. The projection module includes a light source and a diffractive optical element. The imaging module includes an image sensor and a monitoring module. The imaging lens, the monitoring module includes a first monitoring unit, a second monitoring unit and a control circuit, the first monitoring unit is set in the projection module, and is used to obtain the light source beam and the first ambient light processed by the diffractive optical element; the second The monitoring unit is set in the imaging module to obtain the second ambient light; the control circuit is connected to the first monitoring unit, the second monitoring unit and the light source, and is used to monitor the diffraction according to the data of the first monitoring unit and the second monitoring unit Integrity of optical components and control of the light source; fully considering the impact of ambient light, the judgment results are more accurate, avoiding laser safety problems caused by damage to diffractive optical components, and better protecting the depth camera.

Description

technical field [0001] The present invention relates to the field of optical technology, and more particularly, to a depth camera and a depth camera protection method. Background technique [0002] With the development of science and technology, 3D imaging technology has become more and more mature, and the depth camera using 3D imaging technology is currently a hardware device commonly used for 3D imaging. The core device in the depth camera includes a projection module. The projection module usually includes a light source and a diffractive optical element (Diffractive Optical Elements, abbreviated as DOE). The diffractive optical element is used to receive the light beam emitted by the light source, and generate a patterned light beam and then exit. . As the core component of the projection module, the performance of the diffractive optical element directly determines the quality of the patterned beam projected by the projection module and the imaging quality of the dept...
