Abstract: A 3D imaging system uses a depth sensor to produce a coarse depth map, and then uses the coarse depth map as a constraint in order to correct ambiguous surface normals computed from polarization cues. The imaging system outputs an enhanced depth map that has a greater depth resolution than the coarse depth map. The enhanced depth map is also much more accurate than could be obtained from the depth sensor alone. In many cases, the imaging system extracts the polarization cues from three polarized images. Thus, in many implementations, the system takes only three extra images—in addition to data used to generate the coarse depth map—in order to dramatically enhance the coarse depth map.

Abstract translation: 3D成像系统使用深度传感器来产生粗糙深度图，然后使用粗略深度图作为约束，以便校正从偏振线索计算的不明确的表面法线。 成像系统输出比粗糙深度图具有更大深度分辨率的增强深度图。 增强的深度图也比仅从深度传感器获得的精度更准确。 在许多情况下，成像系统从三个偏振图像提取偏振线索。 因此，在许多实现中，除了用于生成粗略深度图的数据之外，系统仅需要三个额外的图像，以便显着增强粗略的深度图。
