Analyze what problems aerial triangulation solves.

The method mainly solves the following problems:

1. Determine the location and geometry of the ground encryption point: By analyzing aerial triangulation, the location and geometry of the ground encryption point can be determined without touching the measured target. This is very important for topographic mapping and other applications.

2. Quickly carry out large-scale point survey: analytic aerial triangulation can carry out large-scale point survey at the same time, saving the workload of field survey.

3. Not limited by visibility conditions: Compared with other measurement methods, analytical aerial triangulation is not limited by visibility conditions and can be measured in complex terrain and environment.

4. Providing orientation control points and photo orientation parameters: Analytic aerial triangulation can provide orientation control points and photo orientation parameters for topographic mapping, thus improving the precision and accuracy of mapping.

5. Calculate the coordinates of a large number of ground points: Analytical aerial triangulation can be used to calculate the plane coordinates and elevations of a large number of ground points, especially for analytical close-range photogrammetry and non-terrain photogrammetry.
