Problems solved by technology

The infrared flood illuminator is generally composed of one or more infrared lasers and a diffusion film. The setting of the infrared flood illuminator not only increases the cost and power consumption of the entire 3D camera, but is not conducive to the miniaturization of the 3D camera.

Embodiment Construction

[0048] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0049] 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. In addition, the connection can be used for both fixing and circuit communication.

[0050] It is to be understood that the terms "length", "...

Abstract

The invention relates to a three-dimensional(3D) camera which comprises a structured light projector, an infrared camera, an RGB camera and a diffuser. The diffuser is arranged on the light emitting side of the structured light projector and comprises two layers of transparent electrodes and a diffusion film clamped between the two layers of transparent electrodes, and the diffusion film is made of a liquid crystal / polymer composite material. The diffuser is in a transparent mode when the voltage is applied, and the structured light projector can emit random dot matrix light to a target objectthrough the diffuser; and the diffuser is in a diffusion mode when the voltage is not applied, and the structured light projector can emit uniform light to the target object through the diffuser. TheRGB camera is used for capturing a two-dimensional(2D) image of the surface of the target object in a bright environment. The infrared camera is used for generating a depth image according to randomdot matrix light of the surface of the target object and capturing a 2D image of the surface of the target object under uniform light in a dark environment. The 3D camera can effectively reduce cost and realize miniaturization.

Description

technical field [0001] The invention relates to the technical field of depth sensing equipment, in particular to a 3D camera. Background technique [0002] In recent years, with the continuous development of the consumer electronics industry, the 3D camera with depth sensing function has been paid more and more attention by the consumer electronics industry. At present, the relatively mature depth measurement method is the structured light scheme, which projects a specific structured light pattern on the object, and then calculates the depth of different positions of the object through the deformation or displacement of the pattern. [0003] Since infrared 2D images also need to be formed in dark environments, a general 3D camera needs to be equipped with an additional infrared flood illuminator to illuminate objects in the dark, and record infrared 2D images with an infrared camera. The infrared flood illuminator is generally composed of one or more infrared lasers and a d...
