Paper Abstract

The inclusion of geometric constraints in a bundle adjustment greatly improves the process of generating accurate, detailed site models, increasing both the precision and the reliability of the solution. This is especially important for our application, using multiple oblique images to automatically generate detailed site models. We have implemented a bundle adjustment which can include constraints between any of the parameters. The program generates precision and reliability statistics for all of the observations, which, since it is based on the unified least squares model, also include the parameters and constraints. This allows evaluation of the added geometric information for blunders. This paper discusses the mathematics and implementation of the program and shows examples of editing both point measurements and constraint information.
