Enhancements for Digital Imaging of Gusset Plate Connections: Fisheye and Image Stitching

This report describes techniques to convert fisheye digital images of gusset plates to perspective images (defish). It also describes methods to stitch together partial images of a gusset plate into a composite of the complete gusset plate. The converted images can be used in rectification and metrification procedures to allow geometric measurements of the connection plates from the processed images. Software applications were written using Matlab to perform the image transformations.
