Computer-Implemented Method for Determining Relative Geometry, Computer Program Product, and Imaging System

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a computer-implemented method for determining the relative geometry between at least two projections of an object obtained from different perspectives using transmission imaging. The method involves solving an optimization problem to estimate the relationship (fundamental matrix) between these projections, considering certain mathematical consistency conditions. The patent also includes a computer program product and an imaging system to perform this method.
