Abstract

3-dimensional (3-D) models made from video recordings are a relatively novel method for mapping and quantifying surface areas of objects. Photos extracted from video and aligned in sequence allow an increase of usable information when compared to discrete photos. The applications of 3-D videogrammetry in this thesis are extremely useful in the tracking of surface areas of living, healthy coral tissue on stony mounding or bouldering corals on reefs. However, during 3-D model generation, errors occasionally develop such as visual distortions or failure to scale accurately. Therefore, an analysis of the accuracy of a 3-D photogrammetry process was conducted. A 3-D printed “coral” and several geometric objects were recorded underwater using a previously used method known as the “Lawnmower” with the addition of 45- and 90-degree angle videos. Successful generation of the models, satisfactory visual quality, and comparison of expected surface area and known surface areas were all used to assess the accuracy of this Lawnmower technique as well as with the addition of angled video coverage.
