An experiment of paved road surface 3D measurement using a consumer digital camera

Recently the total stations and the laser scanners can be available to measure road shape at road paving works by road construction companies. Meanwhile, recent digital camera products provide high-performance and there is a possibility that they will be the other measuring instrument. The purpose of our research is to elucidate the applicability of digital cameras to measure the road shape at the road paving works. In this paper, we report experimental results of applying 3D image processing with a digital camera to a road test piece of asphalt pavement surface with 30 cm square for the road shape measurement.
