Abstract: A technique is provided to facilitate visual recognition of deviations and misalignments in a superposed image. The superposed image is generated by superposing laser scanning point clouds on a panoramic image, which is obtained by stitching base images that are taken from different points of view. The panoramic image can include deviations between the base images. The superposed image can include misalignments between the point cloud image and the panoramic image. A display controlling device for a survey image includes a panoramic image generating unit that generates a panoramic image by stitching multiple still images, an image and point-cloud-image superposing unit that superposes laser scanning point clouds on the panoramic image, and a point-cloud-image transparency adjuster that adjusts a transparency of the image of the laser scanning point clouds to cause the laser scanning point clouds to be visually recognized while the underlying panoramic image is also visually recognized.

Abstract: A surveying system includes a target unit having a reflection target and an encoder pattern showing an angle of the target unit; a scanner configured to acquire three-dimensional point cloud data, measured coordinates of the target, and optically read the encoder pattern to acquire an encoder pattern read angle; and a leveling base configured to selectively allow either of the target unit and the scanner to be removably mounted. The scanner calculates a direction angle of the leveling base based on the encoder pattern read angle and the offset angle of the target unit, calculates coordinates of an installation point of the target unit based on the measured coordinates of the target and the direction angle of the target, and calculates a direction angle of the scanner based on the offset angle of the scanner and the direction angle of the leveling base on which the scanner is mounted.

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.

Abstract: A survey data processing device includes a panoramic image data receiving unit, a point cloud data receiving unit, a similar part designation receiving unit, and a correspondence relationship determining unit. The panoramic image data receiving unit receives first and second panoramic images that are respectively obtained at a first point of view and a second point of view. The point cloud data receiving unit receives first point cloud data that is obtained by a first laser scanner and receives second point cloud data that is obtained by a second laser scanner. The similar part designation receiving unit receives designation of a part that is the same or similar between the first and second panoramic images. The correspondence relationship determining unit determines a correspondence relationship between the first and second point cloud data on the basis of the first and second point cloud data corresponding to the same or similar part.

Abstract: Generation of an inappropriate image portion in an orthographic image due to occlusion is prevented. An image processing device includes an image data receiving part that receives image data of multiple photographed images taken by photographing an object from different positions, a coordinate designating part that receives designation of a specific position in the object, and an optimum-condition satisfying image selecting part that selects a photographed image that is taken from a direction in a specific range relative to the specific position, from among the multiple photographed images. The selected photographed image is used to obtain pixel information of the specific position.

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.
