摘要	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.
其他摘要	根据所公开的实施例，提供了用于使用具有空间和时间交织图案的VCSEL投影仪来实现立体深度相机的系统，方法和装置。例如，描述了一种深度相机，其中具有垂直腔面发射激光投影仪（VCSEL投影仪）;其中VCSEL投影仪包含VCSEL阵列，VCSEL包括多个VCSEL元件，这些VCSEL元件被分成多个VCSEL元件的多个可单独寻址的子集;处理电路，用于激活多个VCSEL元件中的一个或多个可单独寻址的子集，以使VCSEL投影仪通过投影透镜发射多个红外光束，以形成投影到场景上的投影图案;立体图像捕获装置，用于从具有投影在其上的投影图案的场景中捕获立体图像;和处理电路，用于基于从VCSEL投影仪投影的具有其中表示的投影图案的场景捕获的立体图像来确定场景中对象的深度。公开了其他相关实施例。
