What is the impact of just reducing side overlap?

1. First of all, the overlap rate is low. Each feature point will only appear in a small number of aerial photos. The amount of extracted connection points will be very small, and the photos will have few connection points.

2. Secondly, set the overlap rate and expansion. The expansion of oblique photography operation must be at least one row height. After the setting is completed, adjust the route angle to reduce the route length to the shortest.

3. Finally, the connection of the photos of the aircraft is rough, resulting in a weak adjustment structure of the extracted connection points.
