    • The invention is one optical measurement based three-dimension (3D) topology detection equipment. It is conducted to improve the reconstruction accuracy and achieve the objective of acquiring both macro and micro texture morphology. The invention provides a method to acquire both macro and micro texture morphology of pavement at the same time, which can be used to measure characteristics of a surface topology. The proposed method requires six light sources and is improved by adopting low-rank decomposition method, control point-based interpolation surface algorithm to solve normal vector, which can reduce the measurement error and improve the test accuracy. Six highlighting concentrated parallel light sources (HSL-58-105-W) are required in the method. The slant angles of six light sources are all 45° and the tilt angle of six light sources is 0°, 60°, 120°, 180°, 240°, 300°, respectively. The camera is SONY DSC HX-300 digital single lens reflex (SLR) and six photos of pavement texture morphology are taken by the camera under different illumination. Compared with traditional texture morphology test method, the acquisition method in the invention can obviously increase the test precision of texture morphology and acquire macro and micro texture morphology at the same time fast, accurately and repeatedly.
