Embodiment Construction

[0056] In order to make the technical problems, technical solutions and beneficial effects to be solved by the embodiments of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0057] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0058] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other ind...

Abstract

Embodiments of the invention relate to the photoelectric technical field, and provide a projection module and a depth camera. The projection module comprises a base, a light source, a lens supported by an internal bracket, and a pattern generator supported by an external bracket for generating structural optical patterns, wherein the internal bracket and the external bracket are independent non-integrated structures; the internal bracket and the external bracket are mounted on the base; the projection module adopts the internal bracket to support the lens, and adopts the external bracket to bear the pattern generator; the internal bracket and the external bracket are independent structures, so that installation of the lens and the pattern generator can be performed separately without causing mutual constraint; when the internal bracket equipped with the lens and the external bracket equipped with the pattern generator are mounted on the base, the relative positions of the light source, the lens and the pattern generator can be adjusted in a relative easy manner, the installation precision can be controlled easily, the installation efficiency is high and the miniaturization of the depth camera can be facilitated; and in addition, falling off of foreign matters, such as dust and chippings and the like, in the installation process can be avoided, and the lens performance can be ensured.

Description

technical field [0001] The invention belongs to the field of photoelectric technology, and more specifically relates to a projection module, a manufacturing method thereof, and a depth camera including the projection module. Background technique [0002] The structured light depth camera can obtain the depth information of the target to realize functions such as 3D scanning, scene modeling and gesture interaction. Compared with the currently widely used RGB camera, the depth camera is gradually being valued by all walks of life. For example, the use of depth cameras combined with TVs and computers can realize somatosensory games to achieve the two-in-one effect of games and fitness. Technology Co., Ltd.'s name of a depth camera) is one of the representatives. In addition, Google's Tango (Google's research and development project Project Tango) project is committed to bringing depth cameras to mobile devices, such as tablets and mobile phones, so as to bring a completely sub...
