From: A New Pleistocene Hominin Tracksite from the Cape South Coast, South Africa
Photogrammetry of hominin tracks, northern surface. (a) Photogrammetry colour mesh of northern surface, proximal. 3D model was generated with Agisoft Photoscan Professional (v. 1.0.4) using 263 images from a Canon PowerShot ELFPH 340 HS (Focal lengths of 4.5 mm and 4.881 mm; resolution 4608 × 3456; pixel size of 1.33853 × 1.33853 um). Photos were taken average 0.41 metres from the surface. The surface model error is 0.150518 pix. The final images presented here were rendered using CloudCompare (v.2.6.3.beta). (b) Photogrammetry colour mesh of northern surface, distal. 3D model was generated with Agisoft Photoscan Professional (v. 1.0.4) using 198 images from a Canon PowerShot ELFPH 340 HS (Focal length 4.5 mm; resolution 4608 × 3456; pixel size of 1.33853 × 1.33853 um). Photos were taken average 0.45 metres from the surface. The surface model error is 0.132266pix. The final images presented here were rendered using CloudCompare (v.2.6.3.beta). The large track in figure is the same as the track on the far right of (a). (c) Photogrammetry colour mesh, detail of tracks in northern surface beside east wall. 3D model was generated with Agisoft Photoscan Professional (v. 1.0.4) using 155 images from a Canon PowerShot ELFPH 340 HS (Focal lengths of 4.5 mm – 5.082; resolution 4608 × 3456; pixel size of 1.33853 × 1.33853 um). Photos were taken average 0.17 metres from the surface. The surface model error is 0.153466pix. The final image presented here was rendered using CloudCompare (v.2.6.3.beta). The footprint at the far right of this figure is the same as the bottom-most print in (b). For (a,b) and (c), horizontal scale bar, representing x and y axes, is in metres. Vertical scale, representing z axis, is in metres.
