From 3D Perception to Safety Reasoning: A Graph-Based Framework for Real-Time Underground Mine Monitoring
Pasindu Ranasinghe, Simit Raval, Dibyayan Patra +2
Underground coal mining requires personnel and heavy equipment to operate within shared, confined, and poorly illuminated spaces where hazards such as equipment proximity violation…
Towards Integrated Rock Support Visualisation in 3D Point Cloud of Underground Mines
Dibyayan Patra, Simit Raval, Pasindu Ranasinghe +2
The effectiveness of rock support in underground mines depends on the interaction between installed rock bolts and the structural fabric of the surrounding rock mass. However, disc…
Automated Discontinuity Set Characterisation in Enclosed Rock Face Point Clouds Using Single-Shot Filtering and Cyclic Orientation Transformation
Dibyayan Patra, Pasindu Ranasinghe, Bikram Banerjee +1
Characterisation of structural discontinuity sets in exposed rock faces of underground mine cavities is essential for assessing rock-mass stability, excavation safety, and operatio…
LiDAR Point Cloud Colourisation Using Multi-Camera Fusion and Low-Light Image Enhancement
Pasindu Ranasinghe, Dibyayan Patra, Bikram Banerjee +1
In recent years, the fusion of camera data with LiDAR measurements has emerged as a powerful approach to enhance spatial understanding. This study introduces a novel, hardware-agno…
