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: Correspondence relationships between two laser scanning point clouds are easily determined with high accuracy. A data processor includes a laser scanning point cloud acquiring unit and a laser scanning point cloud correspondence relationship determining unit. The laser scanning point cloud acquiring unit acquires a first laser scanning point cloud that is obtained in a first time period and a second laser scanning point cloud that is obtained in a second time period. The laser scanning point cloud correspondence relationship determining unit determines correspondence relationships between the first laser scanning point cloud and the second laser scanning point cloud on the basis of a laser scanning point cloud relating to a fixed object. The fixed object is contained in both the first laser scanning point cloud and the second laser scanning point cloud and does not change between the first time period and the second time period.

Abstract: A method for calibrating unevenness of a plurally of measuring elements in an apparatus for evaluating road surface property having a plurality of measuring elements repeats steps of computing separation quantities from a calibration reference plane on a reference area regarding all measuring elements: determining a measuring element where the separation quantity is maximum from among all the measuring element to calibrate the measuring element such that a difference between point cloud data produced from a measurement value of the measuring element where the separation quantity is maximum and the calibration reference plane becomes equal or less than a predetermined value, producing a new calibration reference plane from the measurement values of the measuring elements including the calibrated measuring element, until RMS of point cloud data does not change.
