    Abstract: Objects of the present disclosure include providing a technique which can efficiently guide an unmanned aerial vehicle to a particular part of a target object. Provided is a control device for an unmanned aerial vehicle including a camera. The control device comprises a bright spot detection unit configured to detect, from an image captured by camera, a bright spot generated by a laser pointer; a flight control unit configured to perform, based on position of the bright spot in the image, flight control over the unmanned aerial vehicle. In such structure, the camera detects the bright spot, generated by the irradiation of spot-type indicating laser beam from the total station, on a wall surface, and the flight control over the unmanned aerial vehicle is performed in a manner that the unmanned aerial vehicle follows the bright spot.

    Abstract: Point cloud data that is missed due to an optical reflection object in measuring point cloud data using a laser scanner is used. A reflection object position calculating device includes a point cloud data receiving unit, a three-dimensional point cloud model generating unit, a missing data part searching unit, a missing data part determining unit, and a reflection object position calculator. The point cloud data receiving unit receives point cloud data. The three-dimensional point cloud model generating unit generates a three-dimensional point cloud model from the received point cloud data. The missing data part searching unit searches for a missing data part of the generated three-dimensional point cloud model. The missing data part determining unit determines whether the found missing data part has a predetermined specific shape. The reflection object position calculator calculates three-dimensional coordinates of the missing data part that is determined as having the specific shape.

    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 that enables easily determining an attitude of a laser scanning apparatus is provided. A surveying device includes a sunlight incident direction measurement unit, a Sun direction acquisition unit, and an attitude calculator. The sunlight incident direction measurement unit measures an incident direction of sunlight that enters a laser scanning apparatus, based on a detected waveform of incident light entering the laser scanning apparatus. The Sun direction acquisition unit acquires a direction of the Sun as seen from the laser scanning apparatus, from astronomical data, based on a position of the laser scanning apparatus. The attitude calculator calculates an attitude of the laser scanning apparatus in an absolute coordinate system, based on the incident direction of sunlight and the direction of the Sun as seen from the laser scanning apparatus, which is acquired from the astronomical data.
