TopoDepth:Topology-Conscious Spatial Coordination for Consistent Depth Field Prediction
This paper introduces TopoDepth, a self-supervised monocular depth estimation framework that leverages topology-conscious spatial coordination. It addresses issues of structural incoherence in dense depth field generation by introducing Topology-Guided Spatial Anchoring (TGSA) and Locally Adaptive Interaction (LAI). TGSA uses spatial anchors for global guidance, while LAI refines local geometric precision. Experiments show improved structural consistency, depth accuracy, and generalization across diverse visual environments, outperforming existing methods like Monodepth2 and SQLDepth on KITTI and Make3D datasets.

| Feature | TopoDepth (Proposed) | Monodepth2 (Traditional) |
|---|---|---|
| Approach | Topology-conscious spatial coordination | Photometric reprojection |
| Structural Consistency | High (spatial anchors, local interaction) | Moderate (depends on reprojection) |
| Generalization | Strong (demonstrated on Make3D) | Good (but less robust to domain shifts) |
| Artifacts | Reduced (coherent boundaries) | Present (boundary drift, inconsistencies) |
Self-supervised Learning
This section explores techniques that enable depth models to be trained from raw image sequences without ground-truth depth, emphasizing photometric and geometric consistency losses, and the challenges of generating coherent representations.

Mitigating Inconsistencies in Dense Depth Fields
Traditional self-supervised methods often struggle with spatial irregularities, causing depth boundaries to drift and scene geometry to lose consistency during the transformation from compact feature embeddings to dense depth representations. TopoDepth's topology-conscious spatial coordination directly addresses this by guiding how depth information is organized and expanded within the decoder, ensuring that global scene topology is retained and local geometric precision is enhanced. This results in more stable structural behavior and clearer transitions, significantly improving the quality of predicted depth maps.
