Description

Jianmin Zhao and six co-authors build a location system for indoor drones where satellite signals fail, in a paper from 2025. Motion sensors drift over time, radio ranges bend when walls block the direct path, and camera tracking drifts when scenes lack features. Each source alone is too weak indoors.

Their system tightly blends motion data, raw radio ranges, camera poses, and height readings in one filter. A check across several time steps throws out bad radio ranges blocked by obstacles. Tests in an underground parking garage beat prior methods on accuracy and stability. Drift from each source was held down well.
