摘要:

立体深度估计依赖于左图像和右图像中的核线上的像素之间的最佳对应匹配来推断深度。在这项工作中,我们重新审视这个问题,从序列到序列对应的角度来取代成本量建设密集像素匹配使用位置信息和注意。这种方法称为STTR(STEreo Transformer),具有以下几个优点:1)放宽了固定视差范围的限制,2)识别遮挡区域并提供置信度估计,以及3)在匹配过程中施加唯一性约束。我们在合成和真实世界的数据集上报告了有希望的结果,并证明STTR即使没有微调也能在不同的领域中推广。

英文摘要:

Stereo depth estimation relies on optimal correspondence matching between pixels on epipolar lines in the left and right images to infer depth. In this work, we revisit the problem from a sequence-to-sequence correspondence perspective to replace cost volume construction with dense pixel matching using position information and attention. This approach, named STereo TRansformer (STTR), has several advantages: It 1) relaxes the limitation of a fixed disparity range, 2) identifies occluded regions and provides confidence estimates, and 3) imposes uniqueness constraints during the matching process. We report promising results on both synthetic and real-world datasets and demonstrate that STTR generalizes across different domains, even without fine-tuning.
