Abstract: Structured light active sensing systems transmit and receive spatial codes to generate depth maps. Spatial codes can't be repeated within a disparity range if they are to be uniquely identified. This results in large numbers of codes for single transmitter/single receiver systems, because reflected ray traces from two object locations may be focused onto the same location of the receiver sensor, making it impossible to determine which object location reflected the code. However, the original code location may be uniquely identified because ray traces from the two object locations that focus onto the same location of the first receiver sensor may focus onto different locations on the second receiver sensor. Described herein are active sensing systems and methods that use two receivers to uniquely identify original code positions and allow for greater code reuse.

Abstract translation: 结构化的光主动感测系统发送和接收空间码以生成深度图。 如果要独特地识别空间代码，则不能在差异范围内重复。 这导致单个发射器/单个接收器系统的大量代码，因为来自两个对象位置的反射光线迹可能聚焦到接收器传感器的相同位置，使得不可能确定哪个对象位置反映了代码。 然而，由于来自聚焦在第一接收器传感器的相同位置上的两个对象位置的射线轨迹可以聚焦到第二接收器传感器上的不同位置，所以可以唯一地识别原始代码位置。 这里描述的是使用两个接收器唯一地识别原始代码位置并允许更大代码重用的主动感测系统和方法。
