Using Underwater Photogrammetry to Map the Maria Concordia mine

Lecture30 minute Lecture|Marcin Stempniewicz

Abstract

Cave Diver Marcin Stempniewicz and the Submerged Foundation team have developed a workflow for using photogrammetry to map underwater passages. Their project involves nearly one hundred hours underwater collecting data, hundreds of hours of digital processing and hundreds of thousands of collected photos to develop a high resolution three dimensional photo-realistic digital representation of the mile long mine. This product can be viewed in a number of different ways, including traditional plan and profile views as well as 3D flythroughs. The Maria Concordia Project has created one of the most detailed underwater passage representations to date with the intent of bringing the end product to a larger diving audience. Marcin will bring and explain the use and limitations of his capture equipment as well as talk about the digital workflow used to create the final product.
