Abstract: A surveying data processing device includes a point cloud data acquiring unit, a three-dimensional model acquiring unit, a first correspondence relationship determining unit, an extended three-dimensional data generating unit, and a second correspondence relationship determining unit. The point cloud data acquiring unit acquires first point cloud data obtained by laser scanning, at a first viewpoint, and acquires second point cloud data obtained by laser scanning, at a second viewpoint. The three-dimensional model acquiring unit acquires data of a three-dimensional model. The first correspondence relationship determining unit obtains a correspondence relationship between the first point cloud data and the three-dimensional model. The extended three-dimensional data generating unit generates extended three-dimensional data in which the first point cloud data is extended, on the basis of the correspondence relationship. The second correspondence relationship determining unit determines a correspondence relationship between the extended three-dimensional data and the second point cloud data.

Abstract: To efficiently and effectively display a plurality of pieces of information that can be acquired from measurement data. Measurement data on a spaced amount from a measurement reference plane at each point of a road measured for a predetermined road width along a measurement path of a road to be measured and road image data including the road acquired along the measurement path are acquired; a unit area to become a unit of processing is set based on the measurement data; a model plane in the unit area is set from the measurement data in the unit area; point group data indicating a spaced amount from the model plane at each point of the unit area is generated; spaced amount display data displaying shading or hue corresponding to a spaced amount specified with the point group data in a contour of the road is generated; and a road image based on road image data corresponding to a specified area of the road and a spaced amount image based on the spaced amount display data corresponding to the road image are simultaneously displayed.

Abstract: To carry out evaluation of a road surface property easily and in a short period of time without being costly. Measurement data of a road surface measured for a predetermined road width along a path of a road to be measured is acquired; a unit area having a preset length dimension along the path in the road width is set along the path; a model plane in the unit area is set based on the measurement data at each point in the unit area; point group data is generated from a spaced amount of the model plane and each point in the unit area, visualize and display the spaced amount in the path, and display a result of evaluation obtained through statistical processing with the path shown on a map.

Abstract: Deviations in a panoramic image obtained by compositing multiple images are corrected. An image processing device includes an image data receiving unit, a selection receiving unit, a three-dimensional position obtaining unit, a projection sphere setting unit, and a composited image generating unit. The image data receiving unit receives data of multiple still images, which are taken from different viewpoints and contain the same object. The selection receiving unit receives selection of a specific position of the object. The three-dimensional position obtaining unit obtains data of a three-dimensional position of the selected position. The projection sphere setting unit calculates a radius “R” based on the three-dimensional position of the selected position and sets a projection sphere having the radius “R”. The composited image generating unit projects the multiple still images on the projection sphere and thereby generates a composited image.
