$\pi$-BA: Probabilistic Neural Bundle Adjustment With Iterative Cycle Optimization for Driving Scene Reconstruction

RA-L 2026

Urban scene reconstruction under noisy camera poses remains a critical challenge for autonomous driving. While recent neural dense Bundle Adjustment (BA) methods have shown promising results in specific settings, their performance often degrades in real-world urban scenarios due to noisy corresponde

Towards Two-view 6D Object Pose Estimation: A Comparative Study on Fusion Strategy

IROS 2022poster

Current RGB-based 6D object pose estimation methods have achieved noticeable performance on datasets and real world applications. However, predicting 6D pose from single 2D image features is susceptible to disturbance from changing of environment and textureless or resemblant object surfaces. Hence,…
