Coordinate indirect measurement method and system based on ARCore

The invention relates to the field of geographic information, and discloses an ARCore-based indirect coordinate measurement method and system, and the method comprises the steps: collecting object feature points, determining a first feature point and a second feature point from the object feature points, and randomly selecting a third feature point from the object feature points; calculating a feature point distance between every two feature points in the first feature point, the second feature point and the third feature point, and calculating a feature point angle of the third feature point based on the feature point distances; calculating a first longitude and latitude course angle of a feature point straight line between the first feature point and the second feature point; identifying a relative position of the third feature point relative to the feature point straight line, and calculating a second longitude and latitude course angle of the third feature point by using the feature point angle and the fi
