Abstract: A technique enables intuitive understanding of a directional relationship between a photographed image and a wide area image, such as an electronic map. An image processing device includes a display controlling unit that displays a quadrangular-shaped photographic image, which is photographed from an aerial vehicle, displays a mark indicating a photographing position of the quadrangular-shaped photographic image, on a wide area image, and performs highlight display in accordance with a corresponding relationship between a direction of the quadrangular-shaped photographic image and a direction of the mark.

Abstract: A technique is provided to enable reduction in cost relating to installation of orientation targets in aerial photogrammetry. A survey data processing device includes a positioning data receiving unit, a relative orientation unit, an absolute orientation unit, and an adjustment calculation executing unit. The positioning data receiving unit receives positioning data obtained by tracking and positioning a reflective prism of an aerial vehicle by a total station. The aerial vehicle also has a camera. The relative orientation unit calculates relative exterior orientation parameters of the camera by relative orientation using photographed images taken by the camera. The absolute orientation unit provides a true scale to the relative exterior orientation parameters by absolute orientation using the positioning data and the relative exterior orientation parameters. The adjustment calculation executing unit corrects the relative exterior orientation parameters having the true scale, by using a positional relationship between the camera and the reflective prism.
