Ramming settlement is a key index to reflect the quality of dynamic compaction. It mainly relies on manual monitoring, which seriously affects construction efficiency, and safety cannot be guaranteed. In this paper, an algorithm Perspective 3-Point Rammer Pose Estimation (P3P-RPE) based monocular vision measurement proposed, can carried out simultaneously with construction, effectively avoiding problem that compaction operation needs terminated during monitoring. Then error propagation model...
Dynamic compaction method (DCM) is currently one of the most commonly used foundation reinforcement techniques. However, manual monitoring still mainstream way DCM tamping counting with low efficiency and high cost. This paper focuses on times DCM, proposes a non-contact Intelligent Monitoring Method for Tamping Times (IM2T2) based machine vision pattern recognition technology. The hammer detection methods cooperative targets, YOLOv4 YOLOv4-tiny are compared, then motion model position...
