Figure 10.
The image illustrates a scatter plot where the X axis indicates bridge width measured in metres and ranges from 0 to 40 metres, while the Y axis represents bridge length in metres, going up to 120 metres. Individual data points are depicted as blue circles and squares, with a density of points concentrated towards the lower left. There are two trend lines, one dashed and corresponding to undamaged bridges with the equation y equals 3.65 x plus negative 1.08, and an R squared value of 0.337. The second line is solid, representing another data fitting for undamaged bridges, with the equation y equals 3.26 x plus 1.96 and an R squared of 0.448. A legend identifies the data point types and trend lines.Scatter plot showing the relationship between bridge length and width for undamaged bridges, based on both ground truth and detection results. The two sets show a high degree of correlation, and the similarity in regression slope and intercept indicates that the structural dimensional relationship is accurately preserved
