UniUGG: Unified 3D Understanding and Generation via Geometric-Semantic Encoding

ICLR 2026poster

Despite the impressive progress on understanding and generating images shown by the recent unified architectures, the integration of 3D tasks remains challenging and largely unexplored. In this paper, we introduce UniUGG, the first unified understanding and generation framework for 3D modalities. Ou…

4D-VLA: Spatiotemporal Vision-Language-Action Pretraining with Cross-Scene Calibration

NeurIPS 2025poster

Leveraging diverse robotic data for pretraining remains a critical challenge. Existing methods typically model the dataset’s action distribution using simple observations as inputs. However, these inputs are often incomplete, resulting in a dispersed conditional action distribution—an issue we refer…

From Flatland to Space: Teaching Vision-Language Models to Perceive and Reason in 3D

NeurIPS 2025poster

Recent advances in LVLMs have improved vision-language understanding, but they still struggle with spatial perception, limiting their ability to reason about complex 3D scenes. Unlike previous approaches that incorporate 3D representations into models to improve spatial understanding, we aim to unlo…

ControlMLLM: Training-Free Visual Prompt Learning for Multimodal Large Language Models

NeurIPS 2024poster

In this work, we propose a training-free method to inject visual prompts into Multimodal Large Language Models (MLLMs) through learnable latent variable optimization. We observe that attention, as the core module of MLLMs, connects text prompt tokens and visual tokens, ultimately determining the fin…

LaneGraph2Seq: Lane Topology Extraction with Language Model via Vertex-Edge Encoding and Connectivity Enhancement

AAAI 2024technical

Understanding road structures is crucial for autonomous driving. Intricate road structures are often depicted using lane graphs, which include centerline curves and connections forming a Directed Acyclic Graph (DAG). Accurate extraction of lane graphs relies on precisely estimating vertex and edge i…

Translating Images to Road Network: A Non-Autoregressive Sequence-to-Sequence Approach

ICCV 2023oral

The extraction of road network is essential for the generation of high-definition maps since it enables the precise localization of road landmarks and their interconnections. However, generating road network poses a significant challenge due to the conflicting underlying combination of Euclidean (e.…

ONCE-3DLanes: Building Monocular 3D Lane Detection

CVPR 2022poster

We present ONCE-3DLanes, a real-world autonomous driving dataset with lane layout annotation in 3D space. Conventional 2D lane detection from a monocular image yields poor performance of following planning and control tasks in autonomous driving due to the case of uneven road. Predicting the 3D lane…

RCLane: Relay Chain Prediction for Lane Detection

ECCV 2022poster

"Lane detection is an important component of many real-world autonomous systems. Despite a wide variety of lane detection approaches have been proposed, reporting steady benchmark improvements over time, lane detection remains a largely unsolved problem. This is because most of the existing lane det…

CurveLane-NAS: Unifying Lane-Sensitive Architecture Search and Adaptive Point Blending

ECCV 2020poster

We address the curve lane detection problem which poses more real-world challenges than conventional lane detection for better facilitating modern assisted/autonomous driving systems. Current hand-designed lane detection methods are not robust enough to capture the curve lanes especially the remote…
