本文针对室内单目深度估计中因结构复杂、边缘重叠严重及旋转分量大导致的深度推理不准确问题,提出一种基于图像边缘相似性的自监督深度估计网络模型。1)引入图像边缘相似性损失函数,作为形状先验约束,缓解因遮挡和重叠引起的性能下降;2)设计自适应特征聚合模块,融合多尺度特征并保持上下文一致性,增强弱相关场景的语义关联;3)提出旋转量优化模块,通过加权融合不同路径的向量来细化位姿估计中的旋转分量,降低旋转误差。实验结果表明,该方法在NYU Depth V2与ScanNet数据集上的深度预测精度分别达到82.9%与78.0%,优于现有先进方法,能够恢复出细节丰富、边缘清晰平滑的深度图,有效提升了室内场景的深度估计效果。

In this paper, we propose a self-supervised depth estimation network model based on image edge similarity to address the issue of inaccurate depth inference in indoor monocular depth estimation due to complex structures, severe edge overlapping, and large rotational components. First, we introduce an image edge similarity loss function as a shape prior constraint to mitigate performance degradation caused by occlusions and overlaps. Second, we design an adaptive feature aggregation module to fuse multi-scale features while maintaining contextual consistency, thereby enhancing semantic associations in weakly related scenes. Finally, we propose a rotation optimization module that refines the rotational components in pose estimation by weighted fusion of the vectors from different paths, reducing rotation errors. Experimental results show that our method achieves depth prediction accuracies of 82.9% and 78.0% on the NYU Depth V2 and ScanNet datasets, respectively, outperforming existing state-of-the-art methods. The proposed method can recover depth maps with rich details and clear, smooth edges, effectively improving depth estimation in indoor scenes.
