A Two-Stage Payload Dynamic Parameter Identification Method for Interactive Industrial Robots with Large Components (I)

ICRA 2026poster

Taking human-robot collaborative assembly as an example, the methods based on contact forces can improve the assembly efficiency of industrial robots with large components in industrial manufacturing. However, due to the large size, high payload, assembly accuracy and dynamic changes in grip positio…

LAiW: A Chinese Legal Large Language Models Benchmark

COLING 2025main

General and legal domain LLMs have demonstrated strong performance in various tasks of LegalAI. However, their current evaluations lack alignment with the fundamental logic of legal reasoning, the legal syllogism. This hinders trust and understanding from legal experts. To bridge this gap, we introd…

R2LDM: An Efficient 4D Radar Super-Resolution Framework Leveraging Diffusion Model

IROS 2025

We introduce R2LDM, an innovative approach for generating dense and accurate 4D radar point clouds, guided by corresponding LiDAR point clouds. Instead of utilizing range images or bird’s eye view (BEV) images, we represent both LiDAR and 4D radar point clouds using voxel features, which more effect

DiffusionRegPose: Enhancing Multi-Person Pose Estimation using a Diffusion-Based End-to-End Regression Approach

CVPR 2024poster

This paper presents the DiffusionRegPose a novel approach to multi-person pose estimation that converts a one-stage end-to-end keypoint regression model into a diffusion-based sampling process. Existing one-stage deterministic regression methods though efficient are often prone to missed or false de…

Single-Stage Diffusion NeRF: A Unified Approach to 3D Generation and Reconstruction

ICCV 2023poster

3D-aware image synthesis encompasses a variety of tasks, such as scene generation and novel view synthesis from images. Despite numerous task-specific methods, developing a comprehensive model remains challenging. In this paper, we present SSDNeRF, a unified approach that employs an expressive diffu…

EPro-PnP: Generalized End-to-End Probabilistic Perspective-N-Points for Monocular Object Pose Estimation

CVPR 2022oral

Locating 3D objects from a single RGB image via Perspective-n-Points (PnP) is a long-standing problem in computer vision. Driven by end-to-end deep learning, recent studies suggest interpreting PnP as a differentiable layer, so that 2D-3D point correspondences can be partly learned by backpropagatin…

MonoRUn: Monocular 3D Object Detection by Reconstruction and Uncertainty Propagation

CVPR 2021poster

Object localization in 3D space is a challenging aspect in monocular 3D object detection. Recent advances in 6DoF pose estimation have shown that predicting dense 2D-3D correspondence maps between image and object 3D model and then estimating object pose via Perspective-n-Point (PnP) algorithm can a…
