Close-range constrained image sequences

摘要

This paper deals with a novel imaging arrangement for special modeling purpose. The method introduced here will take care of the geometrical consistence of photography. It is based on image ray bundles and is meant for conditions where imaging is accomplished inside the object space (e.g. in case of interior model reconstruction). Imaging is designed to be constrained in terms of camera position and orientation and to consist of two image sequences. The image orientations will be resolved by use of LSQ-estimation in heavily overdetermined conditions. The benefits of overdetermination are discussed and the accuracy assessment in a real experiment is published. The accuracy assessment is accomplished with help of exterior reference and stochastic error propagation.
