Abstract: A position at which evaluation of a defect was performed is easily identified. Relative positional relationships between three-dimensional coordinates of feature points of a photographed object and positions of a panoramic camera 111 are calculated based on a moving image, which is photographed by the panoramic camera 111 while a vehicle 100 travels. The position of the object photographed by a hyperspectral camera 114 is calculated based on the relative positional relationships and exterior orientation parameters of the hyperspectral camera 114 with respect to the panoramic camera 111.
