Rugosity value e.g. macro-rugosity value, determining method for managing wayside campground and motorway, involves extracting macro-rugosity value from three-dimensional modelization of surface region

摘要

The method involves simultaneously acquiring two digital photographic images (1, 2) of region of a surface, and linking the digital photographic images by matching points of the digital photographic images. Three-dimensional modelization (3) of the region of the surface is constructed by triangulation, and rugosity value is extracted from the three-dimensional modelization. The photographic images are acquired by emitting light flash in direction of the region and simultaneously capturing the photographic images.
