    Abstract: To provide a surveying instrument capable of evaluating tracking performance without using a device other than the surveying instrument. In order to attain the object described above, a surveying instrument includes a tracking section that detects a position of a target from a shot image, a virtual target position calculating section, a virtual tracking section that converts a position of a virtual target as if it was captured by the tracking section, a tracking arithmetic section that handles an output of the virtual tracking section the same as an output of the tracking section and determines rotational movements of a horizontal shaft and a vertical shaft, a motor control section, motors that rotate the horizontal shaft and the vertical shaft, and encoders that detect rotation amounts of the horizontal shaft and the vertical shaft.

    Abstract: To eliminate influences of unnecessary reflected light other than a liquid surface in a liquid surface reflection type inclination sensor. In order to attain the object described above, an inclination sensor includes a liquid that forms a liquid surface, an illumination section, a barcode pattern to be illuminated by the illumination section, an optical system that projects the barcode pattern on the liquid surface, a light receiving element that detects the barcode pattern, a storage section that stores a detection image when the liquid surface is removed from an optical path of the optical system, and an arithmetic section that calculates an inclination angle by subtracting the detection image when the liquid surface is removed from a detection image when the liquid surface is present on the optical path of the optical system.

    Abstract: Provided is a method for controlling an ultrasonic motor provided at a rotary shaft of a surveying instrument to meet requirements for a rotation speed and a plurality of operation modes, and a surveying instrument for the same. In the present invention, the ultrasonic motor is controlled by a first signal having a square wave in a range of rotation speed of the rotary shaft from zero to a first speed, controlled by a second signal in which rises or falls of the square wave are sloped in a range from the first speed to a second speed, controlled by a third signal in which rises and falls of the square wave are sloped in a range from the second speed to a third speed, and controlled by a fourth signal in which the drive signal is continuously applied in a range higher than the third speed.

    Abstract: The system 1 of an aspect example is used for building photogrammetry. 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.
