Abstract: Provided is an error prediction apparatus including at least one processor and at least one memory configured to receive environment data of a surveying site in which a surveying instrument is installed, to input the environment data of the surveying site into an error prediction model and predict a predicted error that occurs in a surveying result obtained by the surveying instrument under an environment of the surveying site, and to create display data for displaying the predicted error when the predicted error exceeds an allowable value. The error prediction model is a learned model created by machine learning for a surveying instrument of the same model as the surveying instrument by using a set of the environment data indicating an environment of the time of surveying and error data in a surveying result as teacher data.

Abstract: Provided is a hammering test system. A hammering test system includes a hammering test device including a target, a traveling mechanism for automatically traveling on a to-be-tested surface, a marking mechanism configured to perform marking on the to-be-tested surface, an adsorbing mechanism for adsorbing to the to-be-tested surface, and a hammering test mechanism configured to conduct a hammering test on the to-be-tested surface, and a surveying instrument capable of performing automatic tracking and distance and angle measurements of the target. A hammering test is conducted by causing the hammering test device to travel to a desired position while adsorbing to a to-be-tested surface by the adsorbing mechanism. When it is determined that there is an abnormality, a marking is marked on the to-be-tested surface. The surveying instrument automatically tracks the target, and when conducting a hammering test, makes distance and angle measurements of the target.

Abstract: Scanning density of laser scanning is increased at low cost. A laser scanning apparatus includes a horizontal rotation unit and a controller. The horizontal rotation unit determines an area of laser scanning. The controller controls rotation of the horizontal rotation unit. The horizontal rotation unit is rotated while the laser scanning is performed, whereby scanning using laser scanning light is performed in a vertical angle direction at a predetermined interval. The controller makes the horizontal rotation unit repeatedly rotate multiple times in angular ranges that partially overlap one another, in order to perform the laser scanning multiple times on areas of the laser scanning that overlap one another. Start positions of the rotation of multiple times of the horizontal rotation unit are successively shifted by a predetermined amount. The predetermined amount of shifting corresponds to a distance shorter than the predetermined interval.

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.
