Fig. 5: Inspection and structural integrity evaluation of an in-service bridge.
From: Structural integrity of aging steel bridges by 3D laser scanning and convolutional neural networks
a Field 3D scanning with portable equipment. b Rendering of a scanned beam end, the four examined beams are partially stiffened with a concrete diaphragm above the bearing. c Contour maps for documentation of the corrosion phenomenon in the inspection reports. d Input for the convolutional neural network models. The existence of diaphragms and the partial stiffeners is not taken into account similarly to the conventional evaluation techniques.
