The purpose of forward intersection in aerial photogrammetry space

Solve the coordinates of ground points.

According to relevant data, the purpose of the forward intersection of aerial photogrammetry space is to calculate the coordinates of ground points. After using the back intersection of a single image space to obtain the external orientation elements of a photo, it is necessary to deduce the corresponding coordinates from the image points on a single photo.

Aerial photogrammetry refers to the operation of continuously taking photos on the ground with aerial photographic instruments on the plane, and drawing topographic maps in combination with the steps of ground control point measurement, mapping and three-dimensional mapping.
