Problems solved by technology

[0007] It can be understood that the scope of the identifiable area formed by projecting the structured light onto the surface of the space target object within this range meets the user's requirements, and when the target object exceeds this range, due to the formed identifiable area, such as a spot Too large to be received and recognized by the receiving module, as a result, it will affect the imaging effect of the depth camera

Abstract

The invention discloses a structure light projection device. The structure light projection device comprises a laser emitter, a collimating system and a diffractive optical component, wherein the collimating system is arranged on a light path of a light beam emitted from the laser emitter so as to collimate the emitted light beam, the diffractive optical component is arranged at one side, far awayfrom the laser emitter, of the collimating system so that the light beam passing through the collimating system is projected onto a surface of a space target, and the collimating system comprises atleast one adjustable lens for changing a focus point of the collimating system. The structure light projection device disclosed by the invention has the advantages that the optical parameters such asthe focus point and focus distance are changed by the collimating system with the adjustable lens according to an external driving force, so that the identifiable range of the projected light beam isadjusted.

Description

Technical field [0001] The present application relates to a variable focus structured light projection device, and more specifically, to a variable focus structured light projection device capable of changing the optical parameters of the collimation system, and a depth camera and electronic equipment including the variable focus structured light projection device. Background technique [0002] With the development of science and technology, depth camera technology, such as imaging effects, has become more and more perfect, making depth cameras gradually applied to various electronic devices. [0003] As an important component of the depth camera, the structured light projection device will directly affect the function of the entire depth camera. For example, the poor projection effect of the structured light projection module will make the image quality of the entire depth camera poor. [0004] In the current technology, due to technical limitations, the projection distance of the s...
