From: Structural integrity of aging steel bridges by 3D laser scanning and convolutional neural networks
a Eight decommissioned bridge girders are scanned. b Based on the captured point clouds, detailed contour maps are generated for computational calculation of the residual bearing capacity. c Contour maps are created to comply with the input format required by the trained convolutional neural network evaluation tool, including specifications for color map, size, and number of contour layers. Results obtained both for the classification and regression models are presented in Table 2.
