This approach resulted in two distinctly different paths in sensor design, depending on whether the sensor was designed with the different responses to be generated in parallel or serially. Essentially, the dual mechanism allowed either: (1) a reduction in false-positive signals or (2) an enhancement in the detection signal. For example, one ch
The documentation of archeological elements through advanced imaging techniques, finally leading to a detailed 3D model of the objects of interest, is currently a hot topic both in commercial as well as in scientific communities. Some examples of using the 3D technology in this field are listed in [1] and there is even a conference series devoted to this topic [2]. Such a 3D representation is used for visualization, archaeological documentation, restoration, or preservation purposes.

In general we use the term image based modeling [3,4] if we refer to the entire workflow from image acquisition, to image calibration and orientation, to image matching and meshing, or to CAD-like object reconstruction and parameterization.Although software tools which offer support for the entire workflow are available nowadays, a good planning of the initial image acquisition is still necessary in many applications such as in archeology in order to achieve the desired accuracy and reliability of subsequent image processing steps. Moreover, portable physical cultural finds need to be documented first in-situ locations before preserving them in heritage collections and museums [5].

This mission of field data capture in excavation sites is preferred to be automated in order to save time during the capture and ensure adequate data [6]. The mentioned photo acquisition planning demands experience and knowledge in the field of photogrammetry.In the literature few recently presented papers deal with the proper selection and acquisition of images among a large dataset for 3D image-based modeling. Hosseininaveh, et al. [7] introduced a method called Image Network Designer (IND) for the modeling of a museum artifact. Carfilzomib That paper lacks a deep investigation on the accuracy indices after the network reduction and the experiment was tested on small size artifact with only a few images. Wenzel, et al. [8] presented a guideline for image data acquisition called ��one panorama each step��.

They discussed extensively how to find a compromise between large and short base imaging configurations.Previously, we introduced the minimal camera network technique [9] by reducing a pre-designed (simulated) dense imaging network. The redundancy in the information from the dense network will provide freedom for selecting the suitable and sufficient images for the subsequent 3D modeling. This technique is useful, but it fails to accommodate better intersection geometry of rays between cameras and object points and this can result in gaps in the final 3D models.
