Improved Algorithm for Edge Detection of Building Structures and Cracks Based on IFC

For the detection of building structural defects in IFC (Industry Foundation Classes), an accurate edge detection algorithm is needed to identify potential cracks. Traditional edge detection algorithms cannot successfully detect crack edges with special textures or shapes, so an improved algorithm is needed. This article conducted a relevant analysis of crack edge detection algorithms for building structures under the standards of IFC. This article mainly used algorithm comparison and experimental testing methods to explore crack edge detection technology. The experimental data showed that the improved method used in this article had a peak signal-to-noise ratio of 34.1dB, which had a higher quality peak signal-to-noise ratio and minimal error. It could be applied to crack edge detection of building structures.
