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.

Abstract: Provided is a method for controlling an ultrasonic motor to reduce noise sounding during low-speed rotation in a surveying instrument adopting the ultrasonic motor for a rotary shaft, and a surveying instrument for the same. In a method for controlling an ultrasonic motor according to an aspect of the present invention, in a low-speed rotation range of an ultrasonic motor, a ratio of an acceleration period as a time of application of the drive signal in a control cycle is controlled, and a time to start the acceleration period is randomly shifted for each control cycle. In a method for controlling an ultrasonic motor according to another aspect, a time to start the acceleration period is regularly shifted for each control cycle. In a method for controlling an ultrasonic motor according to still another aspect, second-half acceleration control and first-half acceleration control are alternately repeated.

The design data 141 includes virtual material information, which includes virtual material position information, on attributes for each virtual material of a virtual building. The physical material data 142, which includes physical material position data, is generated based on measured data of a physical building constructed based on the design data 141, relates to the attributes for each physical material. The material associating processor 151 generates pairs of virtual and physical materials by determining an association between the virtual and physical materials based on the virtual material position information and the physical material position data. For each of the pairs, the attribute associating processor 152 determines an association between the virtual material information and the physical material data in accordance with the attributes.
