Evaluation of object reconstruction by changing the camera constant

Michał Kowalczyk

Abstract

Evaluation of object's semi three-dimensional model determination was the purpose of this research, in conditions when the analyzed scene is placed in close range from camera station. For experiments there had been recorded movie from a single camera position. Proper acquirement of a third dimension along Z-axis in depth direction was allowed by registering sequential images of a scene, while changing the value of a focusing distance only. Presented approach, prepared as uncomplicated as possible, has many advantages in comparison to standard photogrammetric technology. This case makes dispensable moving camera during registration, what delivers stability of recording process. Video coder’s behavior also ought to be detail lose preventing. Identification of the same object's parts in different frames from this kind of movie is obvious, when scale of the images stays still, or approximately remains constant. Beside this advantages, no rotation problems exist, camera stays stable. There are also disadvantages of this solution, like a necessity of short distance from camera to object preservation and bright lens usage. When properly applied, presented technique could find it's place in a lot of industrial and other non-topographic areas, also as initial approximation for precisely working measurement systems. The main aim of presented paper was an achievement of maximum simplification of this measurement method with possibly low cost.
