PanoFuse: Panorama-Enhanced Vision-Language-Action Learning with Decoupled Semantic-Geometric Routing
See beyond the local view.
Abstract
Vision-Language-Action (VLA) policies have shown promising performance in language-conditioned robotic manipulation, but conventional perspective cameras provide only limited fields of view and may miss global scene context under occlusion, distractors, and unseen environments. We propose PanoFuse, a panorama-enhanced VLA framework that complements local wrist-camera observations with global panoramic perception. A dedicated panoramic branch leverages a pretrained panoramic foundation model to extract complementary semantic and geometric representations. Rather than directly mixing these heterogeneous features, Decoupled Semantic-Geometric Routing (DSGR) maintains them as separate context streams and selectively routes them to downstream state and action representations through structured block-wise attention. We further develop a synchronized teleoperation pipeline and collect a real-world manipulation dataset containing panoramic RGB observations, wrist-view images, language instructions, robot states, and actions. Across seven evaluation settings, PanoFuse reaches an average success rate of 52.9% and shows consistent improvements under novel-object, unseen-background, and distractor-rich settings.
Overview
PanoFuse uses a wrist RGB camera for local manipulation detail and an Insta360 X5 panoramic camera for continuous 360° global context. The panoramic stream supports target acquisition, grasping, transfer, and placement across a long-horizon manipulation sequence.
Method
Panoramic semantic and geometric representations are extracted separately and selectively routed to downstream state and action representations.
Panoramic Representation
A frozen Depth Any Panoramas (DAP) model provides complementary semantic and geometric features from the equirectangular panoramic RGB observation.
64 + 64 Context Tokens
Semantic and geometric features are each pooled to an 8×8 grid and projected into the VLM embedding space.
DSGR
Structured block-wise attention keeps semantic and geometric streams separately contextualized while exposing both to downstream state and action blocks.
Teleoperation System & Dataset
Successful demonstrations
50 trajectories per task across four real-world tasks.
Synchronized timesteps
Panoramic RGB, wrist RGB, language, robot state, and action.
Control & recording rate
6-DoF arm joint positions plus a 1-DoF gripper.
Tasks
- Front-Take-Back-Place: transfer a drink from the front workspace to a yellow box on a separate rear table.
- Back-Take-Front-Place: transfer a drink from the rear workspace to the manipulator table.
- Pick-Place: pick a cantaloupe and return it to the vegetable basket.
- Seq-Cup-Insert: sequentially collect multiple cups and place them into a storage box.
