DepthART

Recent geometric foundation models have advanced monocular depth estimation, yet their benefits remain limited for tiny models. We present DepthART, a compact model designed for robust on-device depth estimation across diverse scenes. To address dataset-specific overfitting and unstable metric adaptation under camera shifts, DepthART combines bias-resistant data sampling with camera-conditioned fine-tuning that preserves the distilled encoder while adapting metric scale using camera intrinsics. These designs improve both cross-dataset generalization and metric depth prediction in capacity-constrained models.
