EYEWEAR DISPLAY SYSTEM AND EYEWEAR DISPLAY METHOD

Provided is a technology for facilitating on-site observation without omission in point cloud data observation using a ground-mounted scanner. An eyewear display system 1 includes a scanner 2 configured to irradiate pulsed distance-measuring light and acquire point cloud data as observation data; an eyewear device 4 including a display 41 and configured to detect its own position and direction; a storage device 66 configured to store an observation route calculated in consideration of three-dimensional CAD design data of an observation site and instrument information of the scanner; and an information processing device 60 including a coordinate synchronizing unit 601 configured to synchronize the eyewear device 4 and a coordinate space of the observation route 661, and an eyewear display control unit 602 configured to control display of the observation route on the display 41, wherein the eyewear device 4 superimposes and displays the observation route 661 on a landscape of the site.
