Embodiment Construction

[0032] The present invention will be further described below with reference to the accompanying drawings and in combination with preferred embodiments.

[0033] The present invention proposes a laser array for 3D imaging, and proposes a corresponding laser projection device and 3D imaging device based on the laser array. The 3D imaging device here is also called a depth camera, and the image of the object captured by the depth camera is The value on each pixel in represents the depth value between the corresponding point in space and the depth camera. In the following description, the laser array, laser projection device and depth camera will be described as examples, but it does not mean that this laser array can only be applied in the depth camera, any other device that uses this solution directly or indirectly should be included in the protection scope of the present invention.

Abstract

The invention discloses a laser array for 3D imaging, a pattern design method for the laser array for 3D imaging, a laser projection apparatus, and 3D imaging equipment. The laser array comprises a plurality of VCSEL light sources which are arranged in a two-dimensional array on a semiconductor substrate; The arrangement mode of the two-dimensional array is formed in a mode of the rotation copying of at least one subarray, and subareas comprising any other quadrant in the arrangement mode of the two-dimensional array obtained in the simple mode of rotation copying of the subarray have irrelevance in any direction. The two-dimensional array is corresponding to the distribution condition of the VCSEL light sources, so the VCSEL light sources distributed on the surface of the semiconductor surface are very high in irrelevance. The laser array solves a problem that the irrelevance of a VCSEL light source for 3D imaging in the prior art is low. The laser array is mainly used in a depth camera.

Description

technical field [0001] The invention relates to the fields of optics and electronics technology, in particular to a laser array for 3D imaging. Background technique [0002] 3D imaging, especially the 3D imaging technology used in the consumer field, will continue to impact or even replace the traditional 2D imaging technology. In addition to the 2D imaging capability of the target object, the 3D imaging technology can also obtain the depth information of the target object. According to the depth information 3D scanning, scene modeling, gesture interaction and other functions can be further realized. Depth cameras, especially structured light depth cameras or TOF (time-of-flight) depth cameras, are currently hardware devices commonly used for 3D imaging. [0003] The core component of the depth camera is the laser projection module. According to the different types of depth cameras, the structure and function of the laser projection module are also different. For example, t...
