MODELS OF CURRENT IMAGES THAT ARE FORMED BY THE COMBINED CORRELATION-EXTREMAL NAVIGATION SYSTEM OF A NON-FLAMMABLE AIRCRAFT

Sučasnì Informacìjnì Tehnologìï u Sferì Bezpeki ta Oboroni, 2018
A refinement of the current image model has been accomplished, which are formed by separate channels of the combined correlation-extreme navigation system depending on the spatial position of the unmanned aerial vehicle and its changes.

TMSA‐Net: Transformer‐Based Multi‐Scale Attention U‐Net for Flood Image Segmentation

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Flood detection is essential for real‐time applications, including disaster management, emergency response, and alerting people in flood zones. For successful flood detection, accurate flood region segmentation is essential. However, the flood region segmentation is challenging due to the complex background and occlusions with debris and the ...

Research on the Online Diagnosis Method for Heating Types of Composite Insulator

High Voltage, EarlyView.
ABSTRACT In response to the current challenge of accurately determining the specific heating status of composite insulators with localised temperature rise using infrared detection technology, this paper proposes a novel diagnostic method. This method involves applying a disturbance to monitor the surface temperature rise data of composite insulators ...

Modelling the Four‐Dimensional Power Line Sag Dynamics by Point Signature in Time‐Series Synthetic‐Aperture Radar Images

High Voltage, EarlyView.
ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

Autonomy for Unmanned Surface Vehicle

, 2018
Autonomous navigation has been successfully presented and developed both on ground and air. Though, autonomy on maritime surface vehicles has proven to be more challenging. In order to have an Autonomous Surface Vehicle (ASV), it ought to have a completely functional Guidance, Navigation and Control (GNC) system.This work presents part of the GNC ...

Research on Self‐Identification Technology of Zero‐Value Insulators in Distribution Lines Based on Electroluminescence Effect

High Voltage, EarlyView.
ABSTRACT To address the issue of low detection accuracy for zero‐value insulators in distribution lines, this study proposes a novel method for detecting these insulators based on the electroluminescence effect. Through theoretical analysis and experimentation, it was found that the luminescence intensity of ZnS:Cu electroluminescent material varies ...
