“…The 2.5D Delaunay triangulation is a classic algorithm used to generate meshes from 3D point clouds [30] and has been used by several researchers to analyze rock faces [1,3,5,[12][13][14]. Poisson surface reconstruction is proposed here as an alternative.…”

“…Jaboyedoff et al [10] addressed this issue by extending the COLTOP-3D coloring scheme to 3D mesh models. Recently, Boivin et al [12] demonstrated the use of grey shades to indicate the dip of triangular mesh elements. McLeod et al [13] developed the concept further and used a Hue Saturation Lightness (HSL) model to color-code strike and dip.…”

“…The strike and dip orientation of the triangular elements were determined by using the normal vec- tor of the triangles and then mapped to the Hue Saturation Lightness (HSL) colour model [Boivin et al 2013]. In this colour model, the 'hue' component determines colour and the 'saturation' component determines the intensity of the colour.…”

This project explored the feasibility of using video images acquired with an unmanned aerial vehicle (UAV) to obtain three-dimensional (3D) point clouds using structure from motion (SfM) software. Missions were flown using an Aeryon Scout: a lightweight, vertical take-off and landing quadrotor micro UAV with a miniature video camera. The initial mission captured urban scene images that were used to assess system performance while the main mission focused on rock walls where 3D images were used to successfully measure fracture orientations. Point clouds generated from this combination of technologies were sparse, but in the future, improvements in the resolution of original video images would cascade through the processing and improve the overall results. Such a system could have a multitude of applications in the mining industry, contributing to both safety and financial considerations.

“…At "local" scale, detailed magnetic mapping can identify magnetic targets of scientific interest, locate subsurface geological features which may host signs of extremophile development, and help to inform the precise locations where to perform astrobiological tests. Examples include the detection of small faults which might be pathways for gas seepage to the surface (methane being of particular interest) (Boivin et al, 2013;Qadi et al, 2015), the delineation of feeder systems of hot springs which are hosts to extremophiles , and the tracking of lava tubes in the subsurface (Meglich et al, 2003).…”

With the recent proliferation of unmanned aerial vehicles (UAV) for geophysical surveying a novel opportunity exists to develop unmanned ground vehicles (UGV) in parallel. This research presents a pilot study to integrate two UGVs, the Kapvik planetary micro-rover and a Husky A200 robotic development platform, with a GSMP 35U magnetometer that has recently been developed for the UAV market. Magnetic noise levels generated by the UGVs in laboratory and field conditions are estimated using the fourth difference method and, at a magnetometer-UGV separation distance of 121 cm, the Kapvik micro-rover was found to generate a noise envelope ± 0.04 nT whereas the noisier Husky UGV generated an envelope of ± 3.94 nT. The UGVs were assessed over a series of successful robotic mapping missions which demonstrated their capability for magnetic mapping, and their productivity and versatility in field conditions.iii Acknowledgements I would first like to thank my supervisor, Dr. Claire Samson, for her tireless support and confidence in the development of this project from start to finish. Dr.Samson's expertise in applied geophysical methods, skill as an editor, and focus on project goals ensured that this experience would be a success. For allowing me the freedom and opportunity to explore research blending the fields of geophysical exploration and robotics, I am eternally grateful. I would like to acknowledge the support of Dr. Alex Ellery, of Carleton University's Mechanical and Aerospace department, for generously providing access to the Kapvik planetary micro-rover and Husky A200 robotic development systems for the duration of this project. Dr. Ellery's insight and advice in discussion of designs and rover integration methodology proved very helpful. I would also like to offer a sincere thank you to GEM Systems Inc. for the loan of the GSMP 35U magnetometer which was a cornerstone of this project. The technical support and knowledgeable team at GEM were a delight to work with. A special thank you to Blair Walker and Mike Wilson for their availability for troubleshooting rovermagnetometer integration issues. To David Boteler, Benôit St-Louis, Lorne McKee, Nathan Olfert, and the Geomagnetism team at NRCAN, thank you for welcoming me at the Ottawa Geomagnetic Observatory over the course of my research. Your expertise in data iv analysis techniques, technical support, and insightful discussions of magnetic methodologies made a large contribution to the successful completion of this project.
