Japanese Patent JP7301514

B2

A coordinate conversion system including a controller that converts geographic-coordinate-system coordinates of a certain point into site-coordinate-system coordinates includes: an image-capturing device that captures an image of a reference point; and a GNSS antenna that receives a navigation signal. The controller calculates geographic-coordinate-system coordinates of the image-capturing device on the basis of the navigation signal received at the GNSS antenna, and a distance between the image-capturing device and the GNSS antenna; calculates a distance and direction from the image-capturing device to the reference point by performing image processing on the image of the reference point captured by the image-capturing device; calculates the geographic-coordinate-system coordinates of the reference point on the basis of the calculated distance and direction from the image-capturing device to the reference point, and the calculated geographic-coordinate-system coordinates of the image-capturing device; and calibrates the coordinate conversion parameter on the basis of the calculated geographic-coordinate-system coordinates of the reference point, and the site-coordinate-system coordinates of the reference point.
