Innovative Technique for Measurement Fingerprint of Cracks and Strain on the Surfaces of the Archaeological Painting, Aswan Case Study
This study aims to measure the cracks on the surface archeologically, measuring strain, documentation the surface exact, and harmless because it does not need to take samples This work presents a modern technological method for measure strain result from cracks and scanning surface for now the number of crack and description it, our tool extracts the properties of each node and edge individually which allows to characterize the cracks statistically. The analyze using Ellipse fit program gives a quantitative valuation of crack lines on the surface and measure the tensile strength and get a chart showing the relationship between the distance and the angle of cracking, and clarify the most areas of the surface exposed to pressure resulting from the cracks as well as the ability to sense develop of the phenomenon of cracks during conservation by comparing the stress value that resulted and the value during conservation .The analysis using Ellipse fit software scans the archaeological surface of each crack on the surface and clarifies information about site , area and direction on the surface and measuring cracks caused by different mechanical behavior of the painting then measure the stress and tension caused by the crack, and provide knowledge about Morphology of crack patterns that are fingerprints for painting and which can be of great importance to cultural heritage. This technology provides the fastest and best way in data and analysis compiled and given the nature of digital data, they are dealing in quantity, and the values of the crack is documented for the paint surface.
