Jaguar head

This model combines the metric accuracy of a scanner (Go!Scan 50) with 0.50 mm accuracy, and high-resolution images to generate an accurate model from both metric and photographic perspectives. Agisoft Metashape software was selected to build the photogrammetric model. Photographs were taken with a Nikon D7000 camera (16.2 megapixels) with a prime 100 mm lens (equivalent to 150 mm due to the crop factor). Lighting was performed with two bi-colour LED panels with a colour rendering index of CRI=95. A total of 55 shots were taken distributed in three circles covering the entire figure. The photographs are processed to obtain images with corrected colour and the maximum resolution and the colour profile generated for the photographic session. CloudCompare open source software was applied for scaling and registration of the meshes.
