Accumulated point cloud and pose from an animal-attached device in a forest environment. Trimmed point cloud from the first stage of the trial. Ground points were labelled using a progressive morphological filter and coloured by height using an elevation filter. Tree trunks labelled by RANSAC are highlighted in green (28 of 30). The position of the device over time, and orientation are represented by the white line and superimposed arrows, respectively. The corner axes represent the orientation of the point cloud. Panels (b) and (c) represent side and top-down views
