A robotic extrusion process is instrumented with a load sensor and assessed with and without activation of the pressure-based controller. The reliability and robustness of a pressure-based closed-loop control system is examined by introducing single- and double-perturbation of the extrusion and assessing the recovery of the geometry (width, height) of the extruded filaments to a baseline reference.

However, current methods suffer from indiscriminate feature extraction that overlooks severe class imbalance, limited adaptability to defects with diverse shapes and appearances, and a lack of publicly available bimodal datasets with multi-class annotations. To address these challenges, this paper proposes Geometric Prior-supported Anti-imbalance Learning (GPAL), a bimodal segmentation framework based on the Segment Anything Model (SAM). GPAL introduces: (1) Defect-centric Reinforcing (DR) prompting, which leverages geometric priors derived from depth flow to enhance the image encoder’s focus on defect details in a defect-oriented manner; and (2) Depth Prototype-support Uniform Prompting (DPUP), which extends SAM for bimodal, multi-class defect segmentation by learning class-balanced depth prototypes. Additionally, the Bimodal Multi-category Pavement Defect (BMPD) dataset is constructed, containing 5,059 samples across four defect categories. Experimental results demonstrate that the proposed method effectively highlights defects under imbalanced conditions and adapts to diverse defects, achieving an mF1 score of 86.01% on the BMPD dataset. This advancement supports reliable pavement assessment and repair decisions, while laying a foundation for addressing class imbalance in diverse tasks through geometric priors and prompting strategies.</div></div>","PeriodicalId":8660,"journal":{"name":"Automation in Construction","volume":"180 ","pages":"Article 106497"},"PeriodicalIF":11.5,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144933684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system was verified using lab tests and computer simulations and was validated using a real-life MiC project. Results demonstrated that the HeLLo system's models outperformed other models such as Newton and Powell in accuracy and efficiency, achieving 25.66 cm in line-of-sight and 36.05 cm in non-line-of-sight accuracies within 1 ms. The HeLLo system ensures centimeter-level accuracy and millisecond-level efficiency to prevent lifting collisions, enhancing safety in MiC.

By leveraging advanced computer vision techniques — such as zero-shot segmentation, depth estimation, edge detection, and dense pixel tracking — critical geometric parameters are extracted and integrated into a kinematic-based model for tension estimation. A calibration-free method for estimating real-world pixel size, derived from the helical geometry of the strands, enables field deployment without the need for camera setup information.
