This paper proposes a new quaternion calibration algorithm to calibrate large misalignment angles between Strapdown Inertial Navigation System (SINS) and Doppler Velocity Log (DVL) in SINS/DVL integrated navigation system. A SINS/DVL/GPS system is derived complete the SINS alignment calibration. Different from traditional model, are described by quaternion, according physical properties of angle scale factor error, measurement equation derived: zero observation vector used estimate angles,...
In this paper, an improved maximum correntropy cubature kalman filter(IMCCKF) is proposed to address the measurement outliers in cooperative localization(CL) of autonomous underwater vehicles (AUVs). The estimated performance filter(MCCKF) algorithm affected by kernel bandwidth(KB). selection value KB cannot be determined only experience practical CL AUVs, which will greatly reduce application MCCKF algorithm. adaptive factor constructed comparing trace size innovation matrix and quantity...
Acrylonitrile–butadiene rubber (NBR) is an important tribological material that often used in dynamic sealing pairs (as rubber/metal seal-pairs), but degrades prematurely because of thermal oxidation ageing. In this work, NBR seals were exposed to accelerated ageing atmosphere at different temperatures and time periods, the aged NBRs evaluated for their mechanical properties, behaviour, energy dissipation. The results showed has a substantial effect on properties. hardness bulk modulus...
In this paper, a new cooperative localization (CL) method for multiple autonomous underwater vehicles (AUVs) is proposed to address the problem of measurement outliers and communication packet loss caused by harsh environment. Combining advantages both maximum correntropy criterion (MCC) adaptive neuro-fuzzy inference system (ANFIS), quality collected data can be improved MCC ANFIS better trained. The efficacy in CL AUVs verified lake trial. experimental results show that effectively obtain...
To deal with the influence of abnormal underwater acoustic ranging errors in cooperative localization autonomous vehicles, a novel measurement information anomaly detection method based on adaptive neuro-fuzzy inference system (ANFIS) is proposed. The can accurately identify and isolate distance exceeding threshold range even when multiple alternately used as data for filtering algorithm. cubature Kalman filter to extract characteristic information, which better reflect change information....
To solve the effect of unreliable acoustic range measurements in cooperative localization autonomous underwater vehicles, a novel method is proposed by using hybrid metaheuristic algorithm that consists adaptive quantum-behaved particle swarm optimization (AQPSO) combined with genetic (GA) to train neurofuzzy inference system (ANFIS) model. The can predict ranging errors online, then correct measurements, and improve accuracy stability system. We first tested ability AQPSO-GA an open-source...
One key challenge of pose transfer lies in its large variation and occlusion. Existing methods are basically aimed at the migration a single input image. As result, these difficult to predict reasonable areas invisibility cannot decouple shape style clothing. Although method using image can generate results with correct structure, it keep original details In order tackle this challenge, we present two-stage generative model designed for multiple images. The initial stage involves Feature...
