Radar-Modulated Selection Enhances Depth Estimation in State Space Models

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel approach to radar-camera depth estimation by integrating radar data directly into the selection mechanism of state-space models, rather than fusing it externally. This method, termed Radar-Modulated Selection (RMS), injects radar-derived perturbations into the Mamba architecture's scan process, allowing radar influence to grow only where it demonstrably improves accuracy. The system, named SemoDepth, achieves state-of-the-art results on the nuScenes dataset, significantly reducing Mean Absolute Error (MAE) across various ranges and maintaining low latency. RMS also shows robustness against spurious radar returns, outperforming traditional fusion methods. AI

IMPACT Introduces a novel integration of radar data into state-space models for improved depth estimation, potentially advancing autonomous driving perception systems.

    Selection, Not Fusion: Radar-Modulated State Space Models for Radar-Camera Depth Estimation

    arXiv:2605.11840v2 Announce Type: replace Abstract: Radar camera depth estimation turns a very sparse but metric radar signal into a dense depth map. Existing methods combine radar and image features outside the sequence operator of the backbone, through concatenation, confidence…
