Abstract:

In this research, surface area of archaeological potsherds from excavations were measured by our real time, and non-destructive digital measuring system to give a new method of classification instead of weighing potteries. This experimental study proposed a fast approach to sum the surface area of the archaeological fragments, and a portable device which has been designed for the first time, based on RGB and gray-scale ۲D image processing technology and electronic system. unlike most other works, this time both external and internal surface of a fragment has been analyzed and measured through a controllable webcam by using techniques such as image enhancement, edge extracting, segmentation, sobel filter, and linking through MATLAB software, to represent total surface area of unearthed fragments. Even It will be able to compute the length and width of the fragments distinctively in a short time, and finally a file of what has been measured will be reported within ۱۰ seconds later automatically, and researchers or students can have access to that record whether remotely as a remote user from off-site location or as a main user. Presented results proved that it has achieved well founded accuracy compare to conventional methods of measuring but in a shorter period of time. In the other hand, proposed system can be applied to analyze shape and the rate of erosion on the objects of every museum. The structure of the device is innovative, efficient, and functional. Another applicable option is UI (user interface) or an extra access for users to analyze every detail on the fragments by using a digital ruler on the screen. According to tables and figures the results of comparison, the efficiency, and the outputs of our system were significantly different with conventional methods.
