Abstract

Omnidirectional vision systems that enable 360º imaging have been used in several applications. The use of georeferenced omnidirectional images in applications that require high metric accuracy, including 3D reconstruction of buildings facades through panoramic images and also control patches (with aerial view) generation that will contribute in the automation of aerial and orbital images orientation, demand the rigorous calibration of these systems. The main aim of this work is to perform the photogrammetric modeling and the calibration of an omnidirection vision system (SVO) with direct georeferencing. Mathematical models based on the collinearity (points) and the coplanarity (lines) conditions for the calibration of a SVO will be developed. These models will be validated through synthetic images generated in POVRAY software. Experiments with real images from the calibration field will also be accomplished. Besides that, methods for the extraction of points and lines with subpixel accuracy will be developed. The accuracy assessment of the developed models and of the calibration process will be carried out through the statistics in the independent check points and also through the comparison with the results provided by the parametric models.
