The invention discloses a stone cultural relic
weathering degree evaluation method and
system based on a high-definition photography technology, and the method comprises the steps: carrying out the photographing of a stone cultural relic through employing a high-definition close-range photography technology, and obtaining a high-definition image of the stone cultural relic; determining a stone cultural relic
weathering characteristic
color scale;
processing the high-definition image of the stone cultural relic by using an
image processing technology, performing
weathering partition evaluation, and calculating areas of different weathering grades in the stone cultural relic and the
area ratio of the areas to the whole cultural relic; and evaluating the weathering degree current situation of the stone cultural relics. According to the method, the surface color weathering degree coefficient of the stone cultural relics is calculated from three aspects of
protolith weathering degree,
water seepage surface and
pigment weathering by utilizing an
image analysis technology, the overall weathering degree coefficient of the stone cultural relics is quantitatively calculated by adopting a
structural similarity SSIM
algorithm, and the weathering degree of the stone cultural relics is remarkably evaluated, so that the evaluation efficiency is remarkably improved, and the evaluation accuracy is improved. And the problem of quantitative evaluation is solved, and the weathering degree of the stone cultural relics can be visually displayed.
