CNN-Based Camera Pose Estimation and Localisation of Scan Images for Aircraft Visual Inspection
Xueyan Oh, Leonard Loh, Shaohui Foong +5
General Visual Inspection is a manual inspection process regularly used to detect and localise obvious damage on the exterior of commercial aircraft. There has been increasing dema…
UWB Radar SLAM: an Anchorless Approach in Vision Denied Indoor Environments
H. A. G. C. Premachandra, Ran Liu, Chau Yuen +1
LiDAR and cameras are frequently used as sensors for simultaneous localization and mapping (SLAM). However, these sensors are prone to failure under low visibility (e.g. smoke) or…
Marker-Based Localisation System Using an Active PTZ Camera and CNN-Based Ellipse Detection
Xueyan Oh, Ryan Lim, Shaohui Foong +1
Localisation in GPS-denied environments is challenging and many existing solutions have infrastructural and on-site calibration requirements. This paper tackles these challenges by…
Monocular UAV Localisation with Deep Learning and Uncertainty Propagation
Xueyan Oh, Ryan Lim, Leonard Loh +3
In this paper, we propose a ground-based monocular UAV localisation system that detects and localises an LED marker attached to the underside of a UAV. Our system removes the need…
Initialisation of Autonomous Aircraft Visual Inspection Systems via CNN-Based Camera Pose Estimation
Xueyan Oh, Leonard Loh, Shaohui Foong +5
General Visual Inspection is a manual inspection process regularly used to detect and localise obvious damage on the exterior of commercial aircraft. There has been increasing dema…
