To do inspections from the model you will need to be very close. Sub 1 cm GSD.
There are several ways to do this, but I highly recommend the following.
1. Agisoft Metashape. Fly the tower to obtain a low resolution model. Then use Agisoft Flight Planner to create a mission. You can set the mission to be whatever distance you need. You can achieve ultra low GSD. You will need RTK to do this as you need cm precise positioning. You then import this mission as a waypoint mission into DJI Pilot 2.
2. Matrice 4 E Local Point Cloud. You fly a mission to obtain a low resolution point cloud and then have Pilot 2 create a mission that flies close to the tower. It is similar to above but is completed entirely in Pilot 2.
You could use orbits and facade missions, but the above two are very, very good. If there are a lot of obstacles such as trees and wires the above can handle them to a point. You just have to make sure they are captured in the initial low resolution models so the flight planners can see them and adjust your flights accordingly.
It is extremely nerve wracking to watch a Matrice 4 E fly within 10 feet of every part of a building, missing antennas, trees and the like, hoping and praying that RTK positioning really works, LOL.
