Abstract

An embodiment of the present application provides a depth-of-field imaging module, comprising an imaging lens, a TOF sensor, an RGB sensor, a laser emitter, and an optical path conversion structure. The laser emitter is used to emit an infrared laser to that camera lens. The camera lens is used for transmitting infrared laser light to the target object. The reflected light beam reflected by the target object is received and transmitted to the optical path conversion structure. Reflected light includes infrared laser and ambient light reflected by the object. The optical path conversion structure is used for dividing at least part of the reflected light ray into a first target light ray and a second target light ray. A first target light is emitted to the TOF sensor and a second target light is emitted to the RGB sensor. The TOF sensor is used for obtaining depth information of a target object from an infrared laser in a first target light. The RGB sensor is configured to obtain RGB information of the target object from ambient light of the second target light. The present application can avoid the problem of low accuracy of the depth-of-field imaging module due to the use of a dualimaging structure.

Description

technical field [0001] The embodiments of the present application relate to the field of camera lens technology, and in particular to a depth-of-field camera module. Background technique [0002] With the rapid development of Internet of Things technology, users have higher and higher demands for intelligent interaction. The depth-of-field camera module is widely used in biometrics, VR (Virtual Reality, virtual Reality) / AR (Augmented Reality, Augmented Reality), autonomous driving, drones, 3D (three-dimensional) projection and other fields. [0003] The existing depth-of-field camera module adopts a dual-camera lens structure, one of which is an RGB (red, green, blue) camera equipped with an RGB sensor for generating an RGB image of a target object, and the other camera lens is a TOF (Time offlight, flight Time ranging method) The camera is equipped with a TOF sensor for collecting the depth information of the target object in three-dimensional space. In addition, a laser...
