Abstract: Versatile and convenient safety management of a construction machine is achieved. Construction machines and workers are photographed by a camera of a surveying apparatus. The images of a construction machine and a worker are identified in the photographic image. The positions of the construction machine and the worker that are identified in the photographic image are measured by the surveying apparatus with the use of laser light. The separation distance between the construction machine and the worker in which the positions are measured is calculated. In the case in which the calculated separation distance is at a threshold or less, a warning is issued to the construction machines and the workers.

Abstract: A technique enables a surveying device to acquire a direction of a target by using as little extra hardware as possible. A method aims a laser scanner, as a surveying device, at a reflective prism that is a target. The method includes obtaining a photographic image of the laser scanner that is captured by a smartphone from the reflective prism side and determining a direction of the reflective prism as seen from the laser scanner on the basis of the photographic image. The method also includes rotating the laser scanner to make the laser scanner face the reflective prism straight on, on the basis of the direction of the reflective prism as seen from the laser scanner.

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: Automation of surveying operations is achieved. When surveying is performed by a surveying apparatus, acquisition of a surveying condition, acquisition of surveying data, acquisition of image data, and acquisition of environmental data are performed. These pieces of data are associated with each other and are stored as learning data. On the basis of this learning data, an AI-estimated model for estimating a surveying condition by using image data of a surveying target and environmental data of a surveying site, is generated.

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.

Abstract: A surveying data processing device includes a point cloud data acquiring unit, a three-dimensional model acquiring unit, a first correspondence relationship determining unit, an extended three-dimensional data generating unit, and a second correspondence relationship determining unit. The point cloud data acquiring unit acquires first point cloud data obtained by laser scanning, at a first viewpoint, and acquires second point cloud data obtained by laser scanning, at a second viewpoint. The three-dimensional model acquiring unit acquires data of a three-dimensional model. The first correspondence relationship determining unit obtains a correspondence relationship between the first point cloud data and the three-dimensional model. The extended three-dimensional data generating unit generates extended three-dimensional data in which the first point cloud data is extended, on the basis of the correspondence relationship. The second correspondence relationship determining unit determines a correspondence relationship between the extended three-dimensional data and the second point cloud data.

Abstract: Information of an instrument point of a surveying apparatus is more simply and easily acquired. Positioning data that is obtained by a first surveying apparatus in which exterior orientation parameters are known, and positioning data that is obtained by a second surveying apparatus in which exterior orientation parameters are unknown, are received. The first surveying apparatus and the second surveying apparatus are configured to obtain positioning data by measuring multiple positions of a UAV that is flying. A piece of positioning data is acquired from the positioning data of the UAV obtained by the first surveying apparatus and from the positioning data of the UAV obtained by the second surveying apparatus. These pieces of positioning data are in a correspondence relationship. The position of the second surveying apparatus is calculated based on the pieces of positioning data that are in the correspondence relationship, by a method of resection.
