Abstract: To enable a worker to intuitively understand a work target place from the worker's perspective while ensuring a highly-accurate position measurement in a work site. A guide system to assist a worker with work in a work site, including: a guide terminal held by the worker having an imaging unit for capturing a new image; an imaging position calculation unit using position information of associated common feature points and a new image to calculate position information of an imaging position and an imaging posture of the new image; a selection unit for selecting a work target that should be guided as to its scheduled installation position; and a guide calculation unit for outputting, to the worker, guide information from the imaging position of the new image to the scheduled installation position of the work target object or the work target point.
