Description

Introduction

We introduce the task of 3D object localization in RGB-D scans using natural language descriptions.            As input, we assume a point cloud of a scanned 3D scene along with a free-form description of a specified target object.            To address this task, we propose ScanRefer, learning a fused descriptor from 3D object proposals and encoded sentence embeddings.            This fused descriptor correlates language expressions with geometric features, enabling regression of the 3D bounding box of a target object.            We also introduce the ScanRefer dataset, containing 51,583 descriptions of 11,046 objects from 800 ScanNet scenes.            ScanRefer is the first large-scale effort to perform object localization via natural language expression directly in 3D.
