Concrete crack detection method based on ConcreteCrackSegNet model

Abstract

The invention provides a concrete crack detection method based on a ConcreteCrackSegNet model, and the method comprises the steps: inputting a picture shot by an unmanned aerial vehicle into the ConcreteCrackSegNet model for detection, and then outputting a predicted segmented concrete crack image through prediction; the ConcreteCrackSegNet model provided by the invention has the characteristics that the concrete crack color boundary is not obvious and the crack has certain continuity according to the concrete crack segmentation specific characteristics combined with the test, the actual concrete crack picture is collected, the picture set comprises various cracks which are not obvious, and the concrete crack color boundary is not obvious. The test fully considers the difficulty in distinguishing and the continuity of the crack. According to the method, the picture segmentation precision is high, and crack damage of the concrete structure can be detected, so that derivation of cracks of the concrete structure can be monitored in an early stage, support is provided for a scientific pre-maintenance decision provided by a maintenance department, and meanwhile, a large amount of manpower and material resources can be saved.

Description

technical field [0001] The invention belongs to the technical field of engineering detection, in particular to a concrete crack detection method based on a ConcreteCrackSegNet model. Background technique [0002] Cracks are a major concern in ensuring the safety, durability, and serviceability of structures because, when cracks develop and propagate, they tend to result in a reduction in the payload area, resulting in increased stress that can lead to concrete or other structures of destruction. As concrete structures age over time, cracks seem inevitable and occur in all types of structures, such as concrete walls, beams, slabs and brick walls, as well as bridges, pavement structures, etc. Especially for concrete elements, cracks can Produces exposure to harmful and corrosive chemicals to penetrate the structure, thereby compromising its integrity and aesthetics. [0003] In fact, for all types of structures, surface cracks are a key indicator of structural damage and dur...

Problems solved by technology

Additionally, manual visual inspection is inefficient in terms of cost and accuracy as it involves subjective judgment by the inspector

The manual process of crack detection is time consuming and subject to the subjective judgment of inspectors

Manual inspections can also be difficult to perform in the case of tall buildings and bridges
