A measurement setup, that is based on the structured light projection method, is developed to obtain a 3-dimensional image of the concrete crack surface. And then authors construct the 2-dimensional analytical method of shape properties from it's 3-dimensional image. Analyzing a measured crack surface by tensioning, some functions are formulated. From the analytical results, the measure sensitivity is about 0.125 millimeter/dot and the sampling interval length is about every millimeters, those were able to show the tendency of the shape properties of the concrete crack surface by tensioning.
