Using 3D Photogrammetry to Quantify Usable Space in Zoo-Housed Primate Habitats.

ABSTRACT: Studies of zoo animal space use typically use ground-level measurements as a proxy for "usable space," but this method ignores above ground areas that are behaviorally relevant to arboreal species. Previous work has proposed different methods to calculate usable above ground space, but each has presented different limitations, ranging from the estimation of areas of dense complexity to the significant manual effort needed to physically measure spaces. To address these limitations, we tested a new, 3D photogrammetry-based method ("3DP method") for calculating usable space in the habitats of two zoo-housed primate species (crowned lemur [Eulemur coronatus], and Bornean orangutan [Pongo pygmaeus]). 3D photogrammetry generates a 3D point cloud and subsequent mesh, using physically captured ima
