Optical phased array (OPA) LiDAR, due to its advantages in solid-state scanning, coherent detection, immunity to mechanical fatigue and external interference, and eye safety, represents a promising direction in next-generation LiDAR technology. Conventional LiDAR-camera calibration approaches generally rely on spatial or reflectivity-based point cloud features to infer shared correspondences, followed by nonlinear optimization. However, three key challenges remain: 1) the absence of publicly available datasets for the emerging OPA LiDAR; 2) inaccuracies from sparse point clouds, foreground inflation, and bleeding points affecting feature correspondence; and 3) reliance on complex calibration targets and computationally intensive processes, reducing robustness and efficiency. To overcome these limitations, we propose, for the first time, four joint calibration methods specifically designed for OPA LiDAR. These methods utilize OPA’s directional scanning to treat each scan point as a reliable 3-D feature that can be directly matched to corresponding 2-D image features, enabling efficient global nonlinear optimization. Experimental validation demonstrates that our methods achieve higher calibration accuracy and significantly reduced computational time compared to existing state-of-the-art techniques. This offers a robust and efficient solution for future multisensor fusion systems centered around OPA LiDAR.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-15"},"PeriodicalIF":5.6,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144492290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To effectively address these problems, this study focuses on exploring advanced object detection technologies and proposes the RT-DETR-LGP model. This model adopts the newly designed multiscale edge information enhancement (MSEIE) module and aggregate diffusion pyramid network (ADPN) module and uses a multiscale feature fusion strategy to achieve efficient detection of defects of different sizes. In addition, this study uniquely combines the model with channel-wise knowledge distillation (CWKD) technology to improve the model’s detection accuracy and generalization ability without increasing the number of model parameters. To comprehensively evaluate the performance of the RT-DETR-LGP model, 10831 LGP defect samples were carefully collected from industrial sites and used to create the industrial LGP defect dataset (ILGPDD) containing seven different types of defects. After integrating the knowledge distillation technology, the RT-DETR-LGP model demonstrated outstanding performance in all key indicators. The <inline-formula> <tex-math>$text {AP},text {AP}_{50}$ </tex-math></inline-formula>, and <inline-formula> <tex-math>${text {AP}}_{75}$ </tex-math></inline-formula> reached 70.3%, 98.0%, and 83.5% respectively, representing improvements of 2.5%, 1.5%, and 2.8% compared to the RT-DETR baseline network. Moreover, the model’s FPS reached 176, indicating its ability to achieve rapid LGP defect detection. These results indicate the great potential of the RT-DETR-LGP model in detecting surface defects of LGPs, providing an efficient and reliable solution for LGP quality inspection in industrial production.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-18"},"PeriodicalIF":5.6,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144501916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, harsh underwater environments severely restrict the study on swimming motion monitoring, where existing studies either focus on a single swimming mode or discrete phases, limiting underwater exoskeleton control. To address this limitation, this article develops a two-stage network (TSN) consisting of one mode classifier (first stage) and four phase regressors (second stage), where muscle deformation features are used instead of traditional joint kinematics. Swimming tests are conducted on nine subjects with four modes at three frequencies. The effectiveness of the proposed method is justified by mode identification accuracy of 99.72% and phase estimation error of 3.92%, where the error is 52.89% smaller than that in the traditional time-based estimation (TBE) method.

The eddy current testing (ECT) has significant advantages in terms of cost and portability over other nondestructive testing technologies such as ultrasonic testing (UT) and X-ray. ECT detects changes in the magnetic field, enabling the detection of the broken steel wires. However, the detection of broken wire ropes in conveyor belts has difficulty in obtaining data under actual working conditions, insufficient data diversity, low recognition accuracy, and poor model generalization ability. This article designs a differential probe and introduces a novel approach, the CutMix-ReliefF-RF method, which addresses these challenges based on the differential signal. By applying CutMix, we enhance the diversity of small sample data and construct varied datasets representing different numbers of broken wires, which significantly improves the model’s recognition ability and generalization performance. The fault features of the broken steel wires in the core of the conveyor belt are extracted, and then the ReliefF method is used for dimensionality reduction to obtain an optimal feature subset. The random forest (RF) algorithm is adopted to identify the broken core characteristics from the eddy current (EC) detection signal. The accuracy of the finite element model (FEM) is validated through experimental and simulation signals used to generate training samples. The proposed method can accurately identify broken steel wires in the core of the conveyor belt, achieving a fault diagnosis accuracy of 98.23% under simulation signals and 96.67% under experimental signals, respectively. This provides strong support for the health monitoring of broken steel wires in the core of the conveyor belt.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-13"},"PeriodicalIF":5.6,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144502881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to complex electromagnetic couplings among multiple conductors, it is difficult to locate faults in coal-mine pulling cables (CMPCs) based on existing circuit models and methods for ordinary ones. In this article, a fault distance estimation method is proposed for CMPCs. Aiming at multiconductor structure and parameters, the lump-parameter equivalent circuit models for analyzing electric quantities along the CMPC in both normal and fault conditions are constructed considering electromagnetic couplings among multiple conductors. The steady-state voltage and current at the fault point are then derived to create fault distance and resistance estimation functions. Finally, the experimental model of CMPCs is established by RTDS. Experimental results demonstrate that the voltage and current computational errors based on the constructed model do not exceed 0.5 V and 0.5 A, respectively. The maximum fault distance estimation error is lower than 13 m with various fault conditions, measurement errors, and noise interferences.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-15"},"PeriodicalIF":5.6,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144519290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The signal quality is usually determined by the electrode–skin interface impedance (EII) and stability of contact interface, where signals may deteriorate due to a change in EII over time by dehydration of conductive gel used in conventional wet electrodes. As a novel type of dry electrode, microneedle array electrodes (MAEs) can penetrate through the stratum corneum and contact the viable epidermis without a touch to the dermis, reducing the EII and forming a stable human-machine interface for signal recording. Various MAEs have been realized by different fabrication methods; however, the performance characterization of MAEs is still insufficient to support and facilitate their applications. In this study, we investigated a type of 3-D-printed MAEs toward high-quality electrophysiological recording. The temporal EII stability of MAEs was investigated by a comparison with the commercially available wet electrodes, which demonstrated the superior performance of MAEs in long-term use. An optimized electrical model for MAEs was proposed, with the RCL connection replacing the normally used RC connection, which showed that the RCL model could achieve a better fitting of EII characteristics for MAEs. Application assessment was fulfilled by recording both electromyography (EMG) and electrocardiography (ECG), which proved the excellent behavior of MAEs in signal recording. In all experiments, no skin allergy, inflammation, or other injury was observed by MAE application. In general, this work may demonstrate a stable and reliable approach for high-quality electrophysiological recording with a strong application potential.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-10"},"PeriodicalIF":5.6,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144314874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
