Hi sarantopoulos.d
thank you for sharing a detailed description of your concerns.
-
Using Pix4Dcapture, by default the drone will always look and move forward along the flight lines established while planning the mission. However it possible in Advanced settings to activate an interesting option called look at the grid’s center. In this case, the drone will always face the center of the grid you planned.

Pix4Dcapture automatically calculates the appropriate camera trigger interval and the drone speed based on the mission’s parameters, including camera specifications, desired overlap, flight height…
Different methods and flight plans which are explained in this post can be used to reconstruct building facades.
From your questions, I suggest you to try a simple grid mission with an oblique camera angle and the drone facing the center of the grid (the center of the grid in your case being the building facade):
- In the Home screen, tap Settings
- In Settings ,** choose the desired angle of the camera**
- In _Settings, _tap advanced tab and select Yes for the Look at the grid’s center option.
Best,
