Regeneration of 3D Profile Line Using a Combination of Photo Images and Target Markers

Abstract

Photogrammetry technique is regarded as one of the promising tools to reconstruct 3D shape from several photo images. The feasibility of the technique is studies in various areas such as, reconstruction of architectural objects, building constructions, industrial products, etc. However, applications of this technique have been conducted for rather large sized objects. This study focuses on this technique and proposes a method of 3D model reconstruction based on the combination of digital camera images and several target markers in order to apply for rather small sized target objects. First, this paper shows the conventional reverse modelling technique. Then, the overview of photogrammetry-based reverse modelling technique is presented to compare it with the conventional method. In order to measure the accuracy of photogrammetry-based reverse modelling, several experiments were conducted, of which results are presented. Some reverse modelling examples based on photogrammetry is presented, including the contour line and surface for freeform surface of a target object.
