The Digitisation and Visualisation of Historical Globes

The Digitization and Visualisation of Historical Globes Abstract The aim of this thesis is to design and verify in practice (semi)automated way of digi- talisation of historical globes. Problematics of point cloud is secured by program Agisoft PhotoScan. The subsequent image processing (data filtering, interpolation, edge enhancement) are performed by own program in Matlab. The result is a universal methodology digitization Globes applicable in almost all cases. As input are included in photos of globe and the output is a raster or mosaic grid showing the surface of the globe. The result is presented in the form of a virtual model of the globe. The methods are described in detail, including mathematical foundations and are subject to criticism. Key words: historical globes, photogrammetry, map projection, image correlation, Matla
