Stereoscopic Polar Plume Reconstructions from Stereo/Secchi Images
, 2009 We present stereoscopic reconstructions of the location and inclination of polar plumes of two data sets based on the two simultaneously recorded images taken by the EUVI telescopes in the SECCHI instrument package onboard the \emph{STEREO (Solar ...

The Photogrammetric Record, Volume 40, Issue 191, July–September 2025.We present a novel pipeline combining photogrammetry and deep learning to map underground utilities. By integrating instance segmentation and vectorization, our method generates attribute‐rich as‐built plans from trench imagery, enhancing GIS integration and enabling efficient, accurate documentation aligned with regulatory requirements for subsurface ...

Enhancment of dense urban digital surface models from VHR optical satellite stereo data by pre-segmentation and object detection [PDF]
, 2010 The generation of digital surface models (DSM) of urban areas from very high resolution (VHR) stereo satellite imagery requires advanced methods. In the classical approach of DSM generation from stereo satellite imagery, interest points are extracted and

Experimental Study of Dike‐Break Induced Flow Generated by Instantaneous Opening of the Side Gate
Journal of Flood Risk Management, Volume 18, Issue 1, March 2025.ABSTRACT A large‐scale experimental model of instantaneous dike‐break induced flow was conducted in this work. Water level variations in the river channel and floodplain, breach discharge, and the surface velocity field at the breach were measured during dike failure.

Hybrid Dynamic Point Removal and Ellipsoid Modelling of Object‐Based Semantic SLAM
IET Cyber-Systems and Robotics, Volume 7, Issue 1, January/December 2025.ABSTRACT For the issue of low positioning accuracy in dynamic environments with traditional simultaneous localisation and mapping (SLAM), a dynamic point removal strategy combining object detection and optical flow tracking has been proposed. To fully utilise the semantic information, an ellipsoid model of the detected semantic objects was first ...

Recursive Estimation of Camera Motion from Uncalibrated Image Sequences [PDF]
, 1994 In This memo we present an extension of the motion estimation scheme presented in a previous CDS technical report [14, 16], in order to deal with image sequences coming from an uncalibrated camera. The scheme is based on some results in epipolar geometry

Deep Depth‐Flow Odometry With Inertial Sensor Fusion
Electronics Letters, Volume 61, Issue 1, January/December 2025.This letter presents a novel visual‐inertial odometry framework that fuses inertial measurement unit measurements with deep learning‐based optical flow and depth predictions to improve pose estimation accuracy. By leveraging optical flow consistency and monocular depth estimation, the proposed method effectively mitigates scale drift, a common issue in
