Concetti Chiave

Introducing DOrA, a novel 3D visual grounding framework with Order-Aware referring, leveraging Large Language Models to improve grounding accuracy.

Sintesi

The content introduces DOrA, a 3D visual grounding framework that utilizes Large Language Models to parse language descriptions and suggest a referential order of anchor objects. It aims to update visual features and locate the target object during the grounding process. Experimental results on benchmark datasets show superior performance in low-resource scenarios.

Introduction

Visual grounding aims to ground a target object in a scene from a natural description.
Challenges include finding the only one object described and handling scattered objects.
Limited focus on 3D visual grounding due to complexities in natural language descriptions and object arrangements.

Methodology

DOrA uses Object-Referring blocks guided by referential orders from LLMs for feature enhancement.
Pre-training strategy augments accurate labels and referential orders for training examples.

Experiments

Outperforms state-of-the-art methods on NR3D dataset with limited training data.
Achieves comparable results on ScanRefer dataset when trained with full data.

Results

Ablation studies show the importance of components like pre-training and feature enhancement modules.
Performance saturates at B=4 for referential order length, balancing efficiency and accuracy.

Conclusions

DOrA demonstrates superior performance in 3D visual grounding tasks using Order-Aware referring approach.
