Abstract: Problems occurring due to a difference in point of view between cameras in compositing a panoramic image by using multiple images taken by the cameras are solved. An image processing device includes an image data receiving unit 101, a panoramic image generating unit 102, a designation receiving unit 103, and a single photographic image selecting unit 105. The image data receiving unit 101 receives data of a first still image and a second still image. The panoramic image generating unit 102 projects the first still image and the second still image on a projection sphere to generate a composited image. The designation receiving unit 103 receives designation of a specific position in the panoramic image. The single photographic image selecting unit 105 selects one of the first still image and the second still image, which contains the designated position received by the designation receiving unit 103.

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: 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.

Abstract: Systems and methods are described for colorizing a point cloud comprising a set of point cloud data points associated with a particular object using a plurality of candidate images. For each respective data point in the set of point cloud data points, an image is selected, from a subset of the plurality of candidate images that include an un-occluded point of the particular object corresponding to the respective data point, that has a shortest subject distance to the un-occluded point of the particular object. The respective data point is colorized based on a color in the selected image of the un-occluded point of the particular object corresponding to the respective data point.

Abstract: Working efficiency in position matching of multiple point cloud data displayed on a display is improved. A point cloud data processing device includes a highlight controlling part. In a condition in which a first point cloud containing multiple markers for position matching and a second point cloud containing multiple markers for position matching are displayed on a display, when a marker of one of the first point cloud and the second point cloud is specified, the highlight controlling part highlights a corresponding marker of the other point cloud.
