The development of intelligent vehicle systems has progressed through multiple stages, evolving from initial basic functionalities to the integration of intelligent and automated technologies, achieving significant advancements. With technological advancements, intelligent vehicle systems have gradually introduced driving assistance features such as autonomous driving assistance and adaptive cruise control. In response to the developmental needs of intelligent driving school vehicle systems, a comprehensive research proposal is presented based on digital twin technology. By incorporating a multi-source data acquisition module, real-time collection and monitoring of various sensor data within the driving school vehicles are achieved, ensuring the acquisition of crucial information during the driving process. To facilitate efficient communication between the data monitoring center and the driving school vehicles, a driving school local area network is established, providing a solid foundation for data transmission and real-time monitoring. A user-friendly and intuitive front-end interface is designed to visualize vehicle status information and student driving data for instructors, enhancing the efficiency and effectiveness of driving school education. Finally, based on practical application tests, data processing of coordinate information is conducted and showcased in the front-end interface, validating the feasibility and practicality of the designed system in driving school vehicle management and educational training. © The Author(s) 2024.

FA-MSVNet: multi-scale and multi-view feature aggregation methods for stereo 3D reconstruction

Stereo 3D reconstruction is pivotal in computer vision, requiring effective fusion of local detail and global semantic features. This paper introduces a novel multi-scale, multi-view cascading network that enhances both accuracy and completeness in 3D reconstruction. In this paper, we addresse the critical challenge of fusing local detail and global semantic features across multiple views. Firstly, the Multi-Scale Feature Aggregation Module (SFAM) is proposed which integrates features at various scales within each view to capture fine-grained details and improve point cloud resolution. Secondly, the Feature Enhancement Module (FEM) is designed to enhance features representation by aggregating spatial context, improving point cloud boundary integrity and reducing occlusion artifacts. Thirdly, the Multi-View Feature Aggregation Module (VFAM) utilizes rectified linear attention to merge global contextual information across views, ensuring more coherent and semantically accurate reconstructions. Extensive experiments on three benchmark datasets resulted in experimental improvements of 3.1%, 8.0%, and 3.1%, respectively, demonstrating that our approach achieves competitive results. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.

Cloth-Changing Person Re-Identification (CC-ReID) refers to the technology that can identify the same individual in surveillance scenarios, even after changing their clothes. The core of CC-ReID is to exact cloth-irrelevant identity features. Existing methods usually extract them from body contours, skeletons, human faces, etc. However, information extracted from a single modality is often insufficient. Therefore, we propose a novel Multimodal Interaction Fusion (MIF) framework that could facilitate the deep integration of multimodal information, thereby enhancing the generalization ability of CC-ReID. Specifically, we design a triple-interaction collaborative module that strategically integrates features captured from body posture, original RGB images, and clothes-erased images, maximizing the advantages of each modality and overcoming their limitations. Additionally, we develop an Adapt-Blend Pool (ABP) module that effectively improves pooling methods to enhance the model's ability to process images with complex backgrounds and varied features. Following training, our framework effectively harnesses a variety of modal inputs to capture identity representations independent of clothing accurately. Extensive experimental results on PRCC, LTCC, and VC-Clothes datasets demonstrate the effectiveness of the proposed method. © 2024 IEEE.

Chinese Journal of Mechanical engineering 2023年第5期36卷 120-140页

Additive manufacturing (AM) technology such as selective laser melting (SLM) often produces a high refection phenomenon that makes defect detection and information extraction challenging. Meanwhile, it is essential to establish a characterization method for defect analysis to provide sufcient information for process diagnosis and optimization. However, there is still a lack of universal standards for the characterization of defects in SLM parts. In this study, a polarization-based imaging system was proposed, and a set of characterization parameters for SLM defects was established. The contrast, defect contour information, and high refection suppression efect of the SLM part defects were analyzed. Comparative analysis was conducted on defect characterization parameters, including geometric and texture parameters. The experimental results demonstrated the efects of the polarization imaging system and verifed the feasibility of the defect feature extraction and characterization method. The research work provides an efective solution for defect detection and helps to establish a universal standard for defect characterization in additive manufacturing.
