Abstract: One aspect example is a system for photogrammetry of a building. A memory stores design data and physical material data. The design data includes virtual material information on attributes for each of virtual materials of a virtual building. The physical material data is on the attributes for each of physical materials and generated based on measured data acquired from a physical building constructed on the basis of the design data. A material associating processor is configured to generate pairs of virtual and physical materials by determining an association between the virtual materials and the physical materials based on the virtual material information and the physical material data. An attribute associating processor is configured to determine an association between the virtual material information and the physical material data in accordance with the attributes for each of the pairs.

Abstract: A measurement device and measurement method are provided which are capable of measuring the inclination of a measurement target object surface both with a simple configuration and at high speed. The measurement device includes: a rangefinding light emitting section; a rangefinding unit configured to receive reflected rangefinding light; an optical axis deflection section provided on an optical path common to rangefinding light and reflected rangefinding light, and configured to deflect optical axes thereof; a motor configured to cause the optical axis deflection section to rotate; an emission direction detection unit configured to detect a deflection angle and deflection direction resulting from the optical axis deflection section; and a computation controller that measures the inclination of a measurement target object surface with respect to the emission optical axis on the basis of acquired coordinate data on the measurement target object surface.

Abstract: Effects of multiple reflections in distance measurement using a laser are reduced. A surveying method for measuring a distance to a reflection point that reflects distance measuring light, based on emission and reception of the distance measuring light, includes assuming that a symbol “K” represents a natural number, excluding zero, and determining whether a beam that is received after the (K+1)th light emission is a repeatedly reflected beam of light that has been emitted before the (K+1)th light emission. The beam that is received, after the (K+1)th light emission, at a time corresponding to a period based on a time interval from light emission at or before the Kth light emission until first reception of a beam related to the light emission at or before the Kth light emission, is determined as being the repeatedly reflected beam.

Abstract: When a camera and a surveying device are connected by a synchro cable, and a photographing condition obtaining unit obtains a photographing start time of the camera, a survey control unit makes a survey time measurement unit start time measurement. After the camera and the surveying device are disconnected, the survey control unit starts a survey by a predetermined surveying period ΔT when tracking of the prism starts. Based on the time measurement by the survey time measurement unit, the survey control unit associates the survey result with the photographing position of each image taken by the camera to generate the data for photogrammetry.

Abstract: The data set receiving unit 13 of the information processing apparatus 1 of an aspect example receives a data set that includes at least BIM data. The route setting processor 151 sets a route, which is arranged inside and/or outside a virtual building represented by the BIM data, based on the data set received. The virtual image set generating processor 152 generates a virtual image set of the virtual building along the route, based on the received data set and the set route. The inference model creating processor 153 creates an inference model by applying machine learning with training data that includes at least the generated virtual image set to a neural network. The inference model created is used to identify data of a building material from data acquired by measuring a building.
