In the process of measuring large ancient buildings, the damaged area boundary texture feature distribution is very complex, and it leads to reducing of image reconstruction accuracy for the imperfect regional characteristics, making it difficult to accurately measure. For this reasons, this paper puts forward a kind of measurement method of large buildings damaged area based on boundary features automatic extraction algorithm. According to the curvature of the damaged area boundary estimation results, the key data points are effectively separated from the background combined with seed grating selection and region growing method to large ancient buildings damaged area. The damage area edge in large ancient buildings is reconstructed according to the principle of polygon subdivision and discrete fairing, so as to improve the measurement accuracy of large ancient buildings. The experimental results show that the boundary characteristics of automatic extraction algorithm can effectively reconstruct the large ancient buildings damaged area, and it greatly improves the measurement accuracy.
