LEARNING AND SLAM BASED DECISION SUPPORT PLATFORM FOR SEWER INSPECTION

2020, Mar

Remote Sensing 12.6 (2020): 968.

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.

DENSE STEREO MATCHING WITH EDGE-CONSTRAINED PENALTY TUNING

2018, May

IEEE Geoscience and Remote Sensing Letters 15.5 (2018): 664-668.

10.1109/LGRS.2018.2805916

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.

MULTI-FEATURE REGISTRATION OF POINT CLOUDS.

2017, Mar

Remote Sensing 9.3 (2017): 281.

https://doi.org/10.3390/rs9030281

This paper proposes a multi-feature registration scheme suitable for utilizing point, line, and plane features extracted from raw point clouds to realize the registrations of scans acquired within the same LIDAR system or across different platforms.
