Geometric Object Extraction

Automated Surface Processing and Object Delineation using Differential Geometry for Digital Data

Total Depth provides surface analysis and  processing services to the Geoscience industry that calculates and extracts any surface’s geometric properties and catalogues them into a queryable spatial database.

Since a fundamental property of any surface is its geometric characteristics, these properties reveal features and objects not easily identifiable by visual analysis alone, providing us with a better understanding of the surface morphology.

The technology implements a mathematical breakthrough created specifically for digital surface analysis. With this mathematical innovation, the analysis and parameterisation processes are automated and unbiased, producing stable results without introducing high-frequency coherent noise. Moreover, the geometric characteristics of each and every surface attribute analysed is delivered in a queryable database. Using simple SQL queries, the user can identify, extract and quantify any objects of interest. The user can also look at many surfaces simultaneously by creating optical (vertical) stacks highlighting geometric properties that extend across multiple surfaces (e.g. faults, fractures, complex deformation, anticline, synclines and collapse).

Applications

Regardless of whether the data surface is sourced from potential fields, ortho-photogrammetry or thousands of surfaces from a 3D spatial database of surfaces, processing will identify and quantitatively extract geometric objects quickly and accurately. The technique therefore has applications in: Seismic, Potential Fields, Lidar, Orthophotogrammetry, MRI, Infrared imaging, X-Ray, Satellite Imagery Data and much more.
