Three-dimensional pavement crack detection based on primary surface profile innovation optimized dual-phase computing

Accurate pavement crack detection has long been a challenging task, causing significant difficulties to the pavement management sectors in the managerial decision making. The high complexity of the crack’s characteristics and the less effective of the crack analytical tools are the two crucial aspects to be accounted for. Recently, three-dimensional (3D) technology based high precision crack detection methodologies has undergone extensive …
