Abstract

At resource mining sites, drilling into the ground and bedrock often occurs in geological surveys and blasting explosives filling. However, extracting core samples from underground boreholes is time-consuming, labor-intensive, and difficult to evaluate quantitatively. Visualization of boreholes, which is realized by computer vision technology, allows engineers to evaluate the geological characteristics of underground rocks to determine trajectories and overall budgets. With the help of VR (Virtual Reality) simulation, this research develops a multi-view fiberscope camera system, which obtains videos of a borehole to generate a high-quality 3D borehole model by using one of the 3D photogrammetric techniques, Structure from Motion (SfM).
