{"title":"Parallelization Strategy of Laser Stripe Center Extraction for Structured Light Measurement","authors":"Tao Ye;Xiangpeng Deng;Guopeng Liu;Wei Chen","doi":"10.1109/TIM.2025.3581633","DOIUrl":"https://doi.org/10.1109/TIM.2025.3581633","url":null,"abstract":"Structured light, known for its high precision and noncontact advantages, is widely used in the fields of 3-D reconstruction and object measurement. The extraction of the light stripe center line has a significant impact on the high-precision measurement of structured light. However, traditional geometric approaches and gray centroid methods often struggle to reliably extract the stripe center, while Steger’s subpixel method is hindered by intensive computational demands, making real-time applications challenging. To address these limitations while ensuring the accuracy of laser stripe center extraction, we propose a parallelization strategy for the Steger algorithm, addressing the challenges associated with high-computational load. The proposed method consists of three key components. First, a perspective projection model acts as a filter, transforming high-resolution images into a lower resolution format, thus lightening the load when identifying the region of interest (ROI). The purpose of this step is to enable laser stripe positioning. Second, we enhance the Gaussian convolutional process by implementing a separable convolutional technique, which decomposes 2-D convolution into two 1-D convolutions, thus lowering computational complexity. Finally, we adopt a dual-layer heterogeneous parallel computing mode, where laser stripe positioning and center extraction tasks are executed in parallel across CPU threads, with each thread utilizing the GPU for computation, enhancing operational efficiency by promoting in-depth collaboration between CPU and GPU. Through extensive experiments, our method demonstrates subpixel-level extraction capabilities in high-resolution laser stripe images, significantly improving execution speed while maintaining extraction accuracy. The findings indicate that the proposed approach has significant real-time application potential in the field of stripe center extraction and lays a solid foundation for improving the measurement precision of structured light.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-11"},"PeriodicalIF":5.6,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144501936","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}

This primary field coupling interference (PFCI) is particularly pronounced when using a multiturn, small-loop coil structure, which significantly limits TEM’s effectiveness in near-surface detection. To address this issue, several decoupling techniques have been proposed. Among them, the off-center self-compensation technology is considered effective and has been applied in systems such as airborne TEM. However, this approach has drawbacks because it is susceptible to primary field remanence caused by structural errors, and its eccentric design results in inadequate detection capabilities and lateral resolution. To overcome these limitations, we proposed a new noncoplanar positive compensation decoupling technology. This device enhances structural stability by positioning a positive compensation coil coaxially with the transmitting coil and coplanar with the receiving coil. Additionally, the positive compensation coil effectively enhances the device’s shallow detection capability by both reducing the relative horizontal distance between the transmitting and receiving coils and providing stronger shallow excitation signals. Simulation and field experiment results demonstrate the effectiveness of the new device.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-12"},"PeriodicalIF":5.6,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144492307","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}

Therefore, accurately identifying PD defects is essential to prevent such incidents in the XLPE cable. This study proposes a novel image visibility graph (IVG) theory-aided phase-resolved PD (PRPD) pattern analysis and recognition framework employing an optimally tuned bi-directional long short-term memory (bi-LSTM) classifier for automated PD detection. To this end, several PD defects have been synthetically emulated inside an 11-kV XLPE cable, and the PD signals corresponding to each type of defect are measured using an HFCT sensor. From the obtained HFCT data, the PRPD patterns were generated, which were converted into connected graphs using IVG. Moreover, image visibility patches (VPs) were computed from the graph-converted PRPD plots to quantify the intricate pixel-level changes due to altering discharge patterns. Following that, the frequency of occurrences (FOCs) of the unique visibility codes was computed from the extracted VPs. The visibility features were further employed to train the bi-LSTM classifier for PD defect identification, which yielded high accuracy. Ablation studies with classical convolutional neural network (CNN) models and comparison with previously reported state-of-the-art methods also revealed superior efficiency of the proposed PD detection methodology, suggesting its potential application for automated health monitoring of XLPE cable insulation.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-10"},"PeriodicalIF":5.6,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144501038","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}

Traditional forecasting methods often struggle due to the inherent nonstationarity and multiscale dynamics observed in these data streams. To address these challenges, this article introduces EvolvInformer, a novel long-sequence forecasting framework that integrates ordinary differential equations (ODEs) solver within a ProbSparse self-attention decoder architecture. The ODE module provides a physics-inspired, continuous-time representation of hidden state dynamics, enabling the model to capture subtle fluctuations and abrupt regime shifts commonly found in instrumented load profiles. Comprehensive experiments conducted on five large-scale power load datasets demonstrate that EvolvInformer achieves a 29.7% reduction in mean-squared error (mse) compared to state-of-the-art baseline models while preserving the logarithmic memory complexity characteristic of ProbSparse attention. Moreover, EvolvInformer consistently models both global trends and localized transient phenomena under stringent computational constraints, making it particularly suitable for embedded and edge-based metering applications. By effectively coupling continuous-time modeling via ODE with an efficient sparse attention mechanism for long-sequence forecasting, EvolvInformer provides a robust and scalable solution for measurement-centric load prediction tasks, with broad potential applications in adaptive energy management, grid load forecasting, and metering data quality assessment.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-12"},"PeriodicalIF":5.6,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144536373","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}

As intelligent manufacturing systems demand higher reliability and efficiency, effective TOS methods are essential for ensuring real-time fault diagnosis and predictive maintenance. However, existing TOS methods inadequately account for correlations between test outcomes in metrics modeling and offer limited solutions to the low fault isolation rate (FIR) caused by multiple faults. An innovative TOS approach is developed by considering fault detection rate (FDR) and FIR metrics via the D-vine copula and Bhattacharyya coefficient method, along with an improved binary particle swarm optimization (DVBC-IBPSO) method to minimize the number of required test points. First, the D-vine copula method is introduced to model test metrics, effectively capturing strong correlations between test outcomes. Second, considering the ambiguity group problem induced by multiple faults, a DVBC combined method is developed to quantify the similarity between fault distributions and model the FIR metric. Third, leveraging the constructed test metrics models, an IBPSO algorithm is employed by incorporating a newly designed objective function that selects the most cost-effective test points while ensuring FDR and FIR remain within acceptable thresholds. The proposed method enhances the reliability and efficiency of intelligent manufacturing systems by optimizing fault diagnosis processes and improving overall system health management.

First, the framework employs a multiencoder denoising autoencoder (DAE) architecture to mitigate noise interference in raw sensor data. Subsequently, the proposed MFF-WGAN integrates label information into its adversarial loss function to enable simultaneous generation of diverse fault categories, while incorporating interclass feature discrepancies to refine sample quality. Finally, the developed multifault feature Wasserstein generation adversarial network is tested on the Case Western Reserve University bearing dataset and the laboratory bearing dataset.

It is challenging to apply a model effective on one device directly to another. Many methods now employ domain adaptation algorithms to align their fault distributions for model transferability. However, most methods focus only on aligning either marginal or pseudo-labels-based conditional distributions, ignoring cases where both label and conditional distributions change, along with the unreliable nature of pseudo-labels. This oversight can lead to transfer failures. To tackle this, this article introduces an information theory-based joint distribution alignment model. The algorithm starts by maximizing mutual information between predicted categories and input samples for conditional alignment without pseudo-label involvement. Simultaneously, the model introduces virtual adversarial training with a penalty term to improve the robustness of prediction results. When label distribution changes, the model uses entropy values to assign data in categories unique to the target domain to “outliers,” thus preventing misalignment of these data. In experiments, this algorithm outperformed other domain adaptation-based methods.","PeriodicalId":13341,"journal":{"name":"IEEE Transactions on Instrumentation and Measurement","volume":"74 ","pages":"1-11"},"PeriodicalIF":5.6,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144519414","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}
