Abstract
This paper presents the analysis of dental cast images and new mathematical methods for their evaluation. While depth sensors of sophisticated scanners allow precise spatial data processing, it is possible to use a multi-camera system for direct data acquisition and recognition of selected objects as well.
The main goal of this paper is the analysis of three-dimensional objects to enable numerical evaluation of measurements important for proposals of the appropriate treatment after dental operations. Methods presented include (1) computer analysis of a single de-noised and thresholded image used for detection of its components and (2) presentation of tools for three-dimensional modeling using a double camera system.
The proposed algorithms allow semi-automatic evaluation of measurements between selected objects. The resulting general algorithm can be used both in biomedical applications and engineering to detect measurements in static image frames or videosequences.
