Stereo depth camera using VCSEL with spatially and temporally interleaved patterns

立体深度相机使用具有空间和时间交错图案的VCSEL
著录项
摘要
根据所披露的实施例,提供了用于实施使用具有空间和时间交错图案的VCSEL投影机的立体深度摄像机的系统、方法和技术。例如, 描述了一种深度摄像头, 在其中包含垂直腔表面发射激光器投影机(VCSEL投影机), VCSEL投影机包含了VCSEL阵列, VCSEL由多个VCSEL元件组成, 这些VCSEL元件被划分为多个可单独寻址的VCSEL元件子集; 处理电路激活多个VCSEL元件的可单独寻址子集之一以使VCSEL投影机发出通过投影透镜发出的多个红外光束, 以形成投射到场景上的投影图案; 从场景捕获立体图像的设备捕捉具有投影图案投射在上面的场景中的立体图像; 和处理电路基于从具有投影图案的场景中捕获的捕获的立体图像来确定场景中物体的深度。其他相关的实施例也被揭示。
【原文】In accordance with disclosed embodiments, there are provided systems, methods, and apparatuses for implementing a stereo depth camera using a VCSEL projector with spatially and temporally interleaved patterns. For instance, a depth camera is described having therein a Vertical-Cavity Surface-Emitting Laser projector (VCSEL projector); in which the VCSEL projector embodies a VCSEL array, the VCSEL being comprised of a plurality of VCSEL elements divided into a plurality of individually addressable subsets of the plurality of VCSEL elements; processing circuitry to activate one or more of the individually addressable subsets of the plurality of VCSEL elements to cause the VCSEL projector to emit a plurality of infrared beams through a projection lens to form a projected pattern which is projected onto a scene; stereoscopic image capture devices to capture stereoscopic imagery from the scene having the projected pattern projected thereupon; and processing circuitry to determine depth to an object in the scene based on the captured stereoscopic imagery from the scene having the projected pattern represented therein as projected from the VCSEL projector. Other related embodiments are disclosed.
