摘要:

深度立体匹配在通过逐领域微调于基准数据集上取得卓越表现方面已取得巨大进展。然而,实现强大的零样本泛化能力——其他计算机视觉任务中基础模型的标志——对于立体匹配而言仍具挑战。我们引入了FoundationStereo,一个旨在实现强大零样本泛化的立体深度估计基础模型。为此,我们首先构建了一个包含1M立体对的大规模合成训练数据集,具有高度的多样性和高逼真度,随后采用自动自筛选流程来移除模糊样本。接着,我们设计了多个网络架构组件以增强可扩展性,包括一个侧向微调特征主干网络,它从视觉基础模型中适配丰富的单目先验知识以缓解仿真到现实的差距,以及用于有效代价卷滤波的长程上下文推理。这些组件共同带来了跨领域的强大鲁棒性和准确性,为零样本立体深度估计树立了新标准。项目页面:https://nvlabs.github.io/FoundationStereo/

英文摘要:

Tremendous progress has been made in deep stereo matching to excel on benchmark datasets through per-domain fine-tuning. However, achieving strong zero-shot generalization - a hallmark of foundation models in other computer vision tasks - remains challenging for stereo matching. We introduce FoundationStereo, a foundation model for stereo depth estimation designed to achieve strong zero-shot generalization. To this end, we first construct a large-scale (1M stereo pairs) synthetic training dataset featuring large diversity and high photorealism, followed by an automatic self-curation pipeline to remove ambiguous samples. We then design a number of network architecture components to enhance scalability, including a side-tuning feature backbone that adapts rich monocular priors from vision foundation models to mitigate the sim-to-real gap, and long-range context reasoning for effective cost volume filtering. Together, these components lead to strong robustness and accuracy across domains, establishing a new standard in zero-shot stereo depth estimation.
