1. A survey assistance system comprising:
a measuring instrument including a communication unit and configured to measure a three-dimensional coordinate of a measuring object;
an eyewear display device including a display, a relative position sensor configured to detect a position of the device itself, and a relative direction sensor configured to detect a direction of the device itself; and
at least one processor configured to match coordinate spaces of the eyewear display device, the measuring instrument, and an absolute coordinate system, to enable information of a position and a direction of the eyewear display device and information of a position and a direction of data created in the absolute coordinate system to be managed in a space with an origin set at a common reference point, and configured to display an image in the absolute coordinate system created by the processor on the display to enable observation of the image superimposed on a site landscape observed with the eyewear display device being worn,
wherein the processor is configured to read out survey process data including at least instrument information of at least one surveying instrument to be used, three-dimensional position information of instrument installation points in the absolute coordinate system, and a measurement order of the instrument installation points, create a work assistance image based on the survey process data, and transmit the work assistance image to the eyewear display device and display the work assistance image on the display, and the work assistance image includes the instrument installation points and images of the surveying instrument to be used showing installed states at the instrument installation points, and the eyewear display device enables observation of the work assistance image by superimposing the work assistance image on the site landscape,
wherein the eyewear display device further includes a camera, the processor is configured to acquire a plurality of landscape images of the entire survey site taken from at least two or more points by using the camera, convert the plurality of landscape images into site three-dimensional data as three-dimensional data of the survey site, calculate a difference between the site three-dimensional data and design data, recalculate the instrument installation points and the measurement order when there is a difference between the site three-dimensional data and the design data, reflect the recalculated instrument installation points and the measurement order in work assistance data, and
wherein the processor is configured to create the work assistance image based on the work assistance data in which the recalculation is reflected.
