Research on the Prediction Method of 3D Surface Deformation in Filling Mining Based on InSAR‐IPIM

Energy Science &Engineering, Volume 13, Issue 5, Page 2401-2414, May 2025.
Aiming at a series of defects existing in the monitoring of mining area by InSAR technology, this paper proposes an insar‐ipim model to predict the three‐dimensional surface deformation of filling mining. The parameters of the model are inversed by using the group optimization algorithm slime bacteria algorithm proposed in 2020, and the empirical ...

A New Technique for INS/GNSS Attitude and Parameter Estimation Using Online Optimization [PDF]

IEEE Trans. on Signal Processing, 62 (10), 2642 - 2655, 2014, 2014
Integration of inertial navigation system (INS) and global navigation satellite system (GNSS) is usually implemented in engineering applications by way of Kalman-like filtering. This form of INS/GNSS integration is prone to attitude initialization failure, especially when the host vehicle is moving freely.

Parallel Parking Path Planning and Trajectory Tracking in Narrow Environments for Autonomous Unmanned Vehicles

Optimal Control Applications and Methods, Volume 46, Issue 3, Page 1235-1248, May/June 2025.
ABSTRACT To address the challenge of parallel parking in narrow environments, a multi‐segment path planning method is proposed for autonomous unmanned vehicles (AUVs), which integrates circular arc and dual clothoid curves, ensuring continuous path curvature and minimal longitudinal space occupancy.
