(SCIE, IF: 10.517, Rank: 1/138)
https://doi.org/10.1016/j.autcon.2022.104731
This study proposes a common framework for both Scan-vs-BIM and BIM-vs-BIM to realize change detection for updating BIM geometric models. The framework can be carried out for point cloud or BIM datasets, in which the framework conveys threefold messages of inspected components between query and reference data: locations, semantic labels, and changing states, namely missing, moving, newly added, existing, and uncertain items.
Three-Dimensional Wireframe Reconstruction for Non-Manhattan-Shaped Point Clouds
2024, Sept.
Journal of Computing in Civil Engineering, 38(6) :
(SCIE, IF: 6.9, Rank: 9/139, 2022)
https://doi.org/10.1061/JCCEE5.CPENG-5965
This study presents a feature relationship algorithm (FRA) for reconstructing 3D wireframes of non-Manhattan objects from segmented point clouds. Rather than extracting boundaries, the FRA identifies vertex and edge nodes and employs an innovative linking strategy to create accurate wireframes, even with missing data. The FRA adapts to various shapes, including curves, cones, pyramids, cylinders, and octagonal prisms. Validations on synthetic and Light Detection and Ranging scan data highlight the FRA's precision and superiority over baseline methods in shape representation.

(SCIE, IF: 5.349, Rank: 30/202)
https://doi.org/10.3390/rs12121908
This paper presents a scheme to conduct moving object recognition with three-dimensional (3D) observation using faster region-based convolutional neural network (Faster R-CNN) with a stationary and rotating Pan Tilt Zoom (PTZ) camera and close-range photogrammetry
Learning and SLAM based Decision Support Platform for Sewer Inspection
2020, Mar.
Remote Sensing 12.6 (2020): 968.
(SCIE, IF: 5.349, Rank: 30/202)
https://doi.org/10.3390/rs12060968
This study developed a compact platform for sewer inspection, which consisted of low-cost components such as infrared and depth cameras with a g-sensor. Except for visual inspection, the platform not only identifies internal faults and obstacles but also evaluates their geometric information, geo-locations, and the block ratio of a pipeline in an automated fashion.
Pavement performance monitoring and anomaly recognition based on crowdsourcing spatiotemporal data

This paper proposes a participatory system for pavement performance monitoring of a country-wide road network based on crowdsourcing spatiotemporal data.
Traffic Sign Detection and Positioning using a Monocular Camera
2019, Sep.
Journal of the Chinese Institute of Engineers 42.8 (2019): 757-769.
(SCIE, IF: 1.107, Rank: 93/175)
https://doi.org/10.1080/02533839.2019.1660220
This study applies a low-cost single-camera system to locate and identify traffic signs and reflects their on-site conditions for assisting in maintenance.
Dense Stereo Matching With Edge-Constrained Penalty Tuning
2018, May.
IEEE Geoscience and Remote Sensing Letters 15.5 (2018): 664-668.
(SCIE, IF: 5.343, Rank: 11/87)
This letter presents a gradual SGM cost aggregation that comprises a penalty tuning process. To be more specific, we propose an additional penalty parameter and a weighting formula to handle edge pixels with depth variations, acquiring satisfactory depth estimation by preserving sharp geometric edges and maintaining smoothness without raising extra noise.

https://doi.org/10.14358/PERS.84.1.25
In this paper, we present an effective strategy for tackling the problem of distortion to improve the performance of spherical image matching.
