摘要 The measurement and description of the three-dimensional (3D) parameters of bridge surface defects are common technical problems in the field of bridge defect detection. These problems are difficult to solve through conventional methods. However, with the assistance of line-shaped lasers, 3D structure measurements can be converted to two-dimensional ones. Based on an analysis of the applications of 3D measurement techniques in other industries, a 3D measurement method for bridge surface defects is proposed. In this method, the parameters of line deformation are measured using digital imaging and pattern recognition techniques, and then the 3D parameters of bridge surface defects are calculated. The computational formula is also deduced. Subsequently, the feasibility of the method is verified by experiments.

Abstract：The measurement and description of the three-dimensional (3D) parameters of bridge surface defects are common technical problems in the field of bridge defect detection. These problems are difficult to solve through conventional methods. However, with the assistance of line-shaped lasers, 3D structure measurements can be converted to two-dimensional ones. Based on an analysis of the applications of 3D measurement techniques in other industries, a 3D measurement method for bridge surface defects is proposed. In this method, the parameters of line deformation are measured using digital imaging and pattern recognition techniques, and then the 3D parameters of bridge surface defects are calculated. The computational formula is also deduced. Subsequently, the feasibility of the method is verified by experiments.
