123d design grid size5/2/2023 ![]() ![]() From the experimental tests in chapter 4, we found that the target accuracy could be maintained with a minimal number of images. The objective function of the optimization is based on minimizing the average error in the object space. To improve the image coverage and accuracy, we used a mathematical non-linear optimization with constraints. The procedure is based on reducing a dense simulated camera network. Starting from a rough point cloud derived from a video image stream, the initial configuration of the camera network was designed, assuming a high-resolution state-of-the-art non-metric camera. In this thesis, we developed an automated method for designing the optimal camera network for a given cultural heritage building or statue. The optimal camera network is designed keeping the number of camera shots at a minimum. This task is, however, quite crucial in practical applications because it needs a thorough planning and a certain level of experience. This modelling starts with designing the camera network for the study object. Image-based modelling techniques are important for producing 3D models in a practical and cost effective manner. The work further contributes to the field of reconstruction through the development of appropriate tools that have been experimentally proved to dramatically increase the number of potential joins that an individual is able to make over period of time. It was also observed that the areas of the virtual workspace used by successful participants was different from the areas used by unsuccessful participants. The experiments include an analysis of the ratio between rotation and movement that show a significant difference between the actions of successful and unsuccessful participants, and an unexpected behaviour that the majority of participants adopted to work with the largest fragments first. ![]() The results of experiments show several interesting behaviours and strategies that participants use when reconstructing cuneiform fragments. The thesis also explores the contemporary and historical state of relevant technologies. This thesis presents the results of experiments to determine the behaviours and actions of participants reconstructing cuneiform tablets in the real and virtual world, and then assesses tools developed specifically to facilitate the virtual reconstruction process. In order for computers to be effective in this context, it is important to understand the current state of available technology, and to understand the behaviours and strategies of individuals attempting to reconstruct cuneiform fragments. Modern computers and ancillary technologies such as 3D printing have the power to simplify the process of cuneiform reconstruction, and open up the field of reconstruction to non-experts through the use of virtual fragments and new reconstruction methods. Reducing the time spent by experts on the process of cuneiform fragment reconstruction means that more time can be spent on the translation and interpretation of the information that the cuneiform fragments contain.
