Efficient and Precise Drone Rephotography for Video Sequences

Hao-Liang Xu, Chu-Chun Chi, Kuan-Wen Chen

IROS 2025

Precise drone rephotography technology aims to recover camera poses from a reference sequence and obtain well-aligned image sequences, playing a crucial role in autonomous drone inspection tasks. However, existing rephotography methods rely on static image inputs, resulting in low efficiency and lim

Photometric Consistency for Precise Drone Rephotography

Hsaun-Jui Chang, Tzu-Chun Huang, Hao-Liang Xu, Kuan-Wen Chen

IROS 2024poster

This paper proposes a precise drone rephotography system for fixed-domain patrolling scenarios. The proposed system integrates computer-vision-based localization and fine-tuned pixel-level dense flow prediction to achieve consistent and precise rephotography images with viewpoints that closely align…
