Abstract: A head-mounted display device has more convenient functions, which is usable in, e.g., surveying. An eyeglass display device includes a display unit and an operation content receiving unit. The display unit is configured to be placed on the head of a user and to be viewed by the user. The operation content receiving unit receives content of operation performed by the user. The display unit displays an image that shows a location relationship between positioning information of a target positioned by a location measuring device by using laser light and a predetermined placement planned location of the target. Multiple coordinate systems are prepared for a coordinate system of the displayed image. The operation content receiving unit receives designation of one coordinate system from among the multiple coordinate systems by the user.

Abstract: In measurement with a surveying device having a surveying function and a laser scanner function, three-dimensional coordinates of a reflecting prism acquired with the surveying function and three-dimensional coordinates of a vertex of a polyhedron generated by processing point group data acquired with the laser scanner function are made to coincide with each other. The reflecting prism is used together with the surveying device having the surveying function and the laser scanner function, is provided to a measurement target object, and is disposed in such a position that the vertex position of the measurement target object coincides with or is considered to coincide with the optical center position of the prism.

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: 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.
