Count the bolts - Geolocate rock bolts in an underground ore drive from 2D and 3D image data
Count the bolts aka Geolocate rock bolts in an underground ore drive from 2D and 3D image data.
•automatically locate bolts from 2D photos and 3D textured mesh
•provide georeferenced locations (CSV and visually)
•provide bolt statistics over a 20m section: total number, average distance apart, density per square meter
•classify condition of bolts: tight against wall or sticking out (stretch goal as imagery may not provide enough detail)
Rock bolts and mesh (ground support) are used to stop underground tunnels from collapsing inwards.
Currently a person will make a visual assessment on the pattern of bolting, as well as the physical condition of each bolt, to determine if ground support is holding well. Due to the sheer number of bolts the time taken to count and map them all is not practical.
A quick, automatic way to count and locate the bolts would make this assessment easier and more objective leading to an improved understanding of ground support performance and hence safer productive mining.
Georeferencing: In a GPS denied environment post processing of data occurs to align data to a particular coordinate system to enable overlay and analysis with GPS located information i.e. drill holes and survey.
