Image-based Detection of Surface Defects in Concrete during Construction. (arXiv:2208.02313v1 [cs.CV])

Defects increase the cost and duration of construction projects. Automating
defect detection would reduce documentation efforts that are necessary to
decrease the risk of defects delaying construction projects. Since concrete is
a widely used construction material, this work focuses on detecting honeycombs,
a substantial defect in concrete structures that may even affect structural
integrity. First, images were compared that were either scraped from the web or
obtained from actual practice. The results demonstrate that web images
represent just a selection …
