Abstract: A technique for facilitating understanding of a stereoscopic structure of an object in a 3-D image of point cloud data is provided. An image processing device includes a point cloud data display controlling unit, a marker display controlling unit, and a specified point cloud display controlling unit. The point cloud data display controlling unit displays a 3-D image of point cloud data on a screen. The marker display controlling unit displays a marker to specify a cut section of the 3-D image of the point cloud data. The specified point cloud display controlling unit displays a point cloud that constitutes the cut section among the point cloud data, as another image.

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.
