a surveying instrument including a distance-measuring section capable of performing a non-prism distance measuring of a measurement point by distance-measuring light, an imaging section configured to perform imaging in an optical axis direction of the distance-measuring light, an angle-measuring section configured to measure a vertical angle and a horizontal angle at which the distance-measuring section is oriented, a drive section configured to drive the vertical angle and the horizontal angle of the distance-measuring section to set angles, and a communication section;

a measuring marker to be carried by a worker, including a position sensor, a posture sensor, a laser emitting section configured to emit laser light of visible light in an axial direction, an emission port for the laser light, a distance meter configured to measure a laser distance from the emission port to the measurement point, and a communication section;

an eyewear device to be worn on the head of the worker, including a display configured to cover the eyes of the worker, an imaging section configured to perform imaging in a line-of-sight direction of the worker, a position sensor, a posture sensor, and a communication section, and

an arithmetic device configured to communicate with the surveying instrument, the measuring marker, and the eyewear device, synchronize coordinate spaces of the surveying instrument, the measuring marker, and the eyewear device, and calculate an identified three-dimensional position of the measurement point by image analysis from images including the measurement point imaged by the imaging section of the surveying instrument and the imaging section of the eyewear device, wherein

the identified three-dimensional positions of a plurality of the measurement points are measured by the surveying instrument in the order in which measurement instructions were issued by the worker.
