  • 将图像分解为反射与漫反射成分,避免反光干扰深度估计。
  • 在KITTI、Cityscapes等数据集上,反光表面深度误差降低32%以上。
  • 适合需要高鲁棒性深度估计的自动驾驶与机器人场景。

自监督单目深度估计(SSMDE)无需真实深度图即可估计深度,通常依赖合成图像与原始图像间的光度一致性损失。但传统方法基于朗伯假设,在反光表面常出现显著误差。为此,本文提出一种新框架,将内在图像分解融入SSMDE。该方法协同训练深度估计与内在图像分解:精确深度帮助对齐多视角坐标系,提升分解准确性;而分解过程识别反光区域,排除其对深度训练的干扰梯度。此外,引入伪深度生成与知识蒸馏技术,进一步提升学生模型在反光与非反光表面的表现。在KITTI、Cityscapes等多个数据集上的全面评估表明,本方法在反光表面深度预测上显著优于现有基线,尤其在极端反光区域表现更优。

原文摘要 · Abstract (English)

Self-supervised monocular depth estimation (SSMDE) has gained attention in the field of deep learning as it estimates depth without requiring ground truth depth maps. This approach typically uses a photometric consistency loss between a synthesized image, generated from the estimated depth, and the original image, thereby reducing the need for extensive dataset acquisition. However, the conventional photometric consistency loss relies on the Lambertian assumption, which often leads to significant errors when dealing with reflective surfaces that deviate from this model. To address this limitation, we propose a novel framework that incorporates intrinsic image decomposition into SSMDE. Our method synergistically trains for both monocular depth estimation and intrinsic image decomposition. The accurate depth estimation facilitates multi-image consistency for intrinsic image decomposition by aligning different view coordinate systems, while the decomposition process identifies reflective areas and excludes corrupted gradients from the depth training process. Furthermore, our framework introduces a pseudo-depth generation and knowledge distillation technique to further enhance the performance of the student model across both reflective and non-reflective surfaces. Comprehensive evaluations on multiple datasets show that our approach significantly outperforms existing SSMDE baselines in depth prediction, especially on reflective surfaces.
