Abstract

The invention discloses a VCSEL array for a 3D depth acquisition device. The VCSEL array comprises light-emitting assemblies and a semiconductor substrate, and the light-emitting assemblies are distributed on the surface of the semiconductor substrate and comprise at least two light-emitting unit groups, wherein each light-emitting unit group comprises a plurality of light-emitting units which arecommunicated with one another, the light-emitting unit groups are distributed on the semiconductor substrate in a mutually staggered manner according to the respective corresponding patterns, and thepatterns corresponding to the light-emitting assemblies formed by the patterns corresponding to the light-emitting unit groups are irregular patterns. The 3D depth acquisition device is provided withat least two groups of wires, and each group of wires is connected with and is used for driving each light-emitting unit group. The invention also discloses a processing method of the VCSEL array andthe 3D depth acquisition device. According to the present invention, the depth precision and the energy consumption obtained in specific 3D application can be well balanced.

Description

technical field [0001] The present invention relates to the field of 3D depth acquisition equipment, in particular to a VCSEL array used for 3D depth acquisition equipment and the 3D depth acquisition equipment. Background technique [0002] 3D depth technology is gradually entering the field of mass consumption. Common technologies include binocular stereo matching, ToF (time of flight) and structured light. Especially structured light technology, which can work in weak texture areas, has high precision and reasonable energy consumption, so it is more and more favored by people. The core component of structured light is the laser projection module, which projects a series of patterns onto the object, while the imaging optical module captures the patterns projected onto the object, and processes the patterns through the processor to obtain the 3D depth information of the object. [0003] As VCSEL (Vertical Cavity Surface Emitting Laser) technology is becoming more and more ...
