The invention discloses a structural crack volume measuring and calculating method and device, equipment and a storage medium, and the method comprises the steps: collecting a plurality of crack sample images through a calibrated and registered depth camera and a monocular camera, and calculating the corresponding crack volume value in each crack sample image; constructing a structure crack volumemeasurement model by taking the acquired crack sample image as input and taking the calculated crack volume value as output; acquiring a crack RGB image of the to-be-detected structure through a monocular camera; and inputting the acquired crack RGB image of the to-be-measured structure into the constructed structure crack volume measurement model for calculation to obtain volume measurement information of the to-be-measured structure crack. The method can greatly improve the detection precision and detection efficiency, is suitable for the measurement of crack volumes of various material structures, is higher in universality, can achieve the real-time non-contact detection, is low in cost, is high in precision, is easy to operate, and provides an effective path for the damage repair andreinforcement of a structure.
Description
technical field [0001] The invention relates to the technical field of engineering structure crack detection, in particular to a method, device, equipment and storage medium for measuring and calculating the volume of structural cracks. Background technique [0002] With the rapid development of the construction industry, there are more and more large-volume reinforced concrete structures in high-rise building structures and underground construction projects. Big trouble, but also buried a serious quality hidden danger to the engineering structure. [0003] In the research on the construction of mass concrete structures, it is found that since the current mass concrete is still in the initial development stage, its structural characteristics, material properties and construction technology requirements, especially the prevention and treatment of mass concrete cracks, are still in the process of exploration and deepening in the process of. [0004] Therefore, in order to en...
