Abstract
In the "Periodic inspection rocedures" of various road structures formulated in June, 2014, it is mandatory to make the regular inspection for existing road structures once every five years. For this reason, technological development for an efficient maintenance management was pointed out as an urgent task. “Mobile Imaging System”, which was developed few year ago, measures road structures by using digital video camera and laser scanner mounted on a specialized vehicle. In addition, the measuring precision is high. However, in many cases the operation cost is expensive. Therefore, it is difficult for local government with budget limitation to apply it to the regular inspection. Authors has developed a reasonable “Mobile Imaging System”, that is an mountd on a maintenace patrol car, measurement accuracy same as a specialized vehicle, decomposable and has developed an image stiching program for panoramic images.
