Cloud Workflow

Mini drone, one flight

Mini 4 Pro orbit + cloud training. Single building in an hour.

Difficulty
Beginner
Time
About 1 hour
Cost
Free cloud quota tier
Best for
Drone newcomers, anyone preserving one building in 3D

Tools you'll use

  • DJI Mini 4 Pro
  • Polycam Drone
  • Luma AI

Step-by-step

  1. 01

    Pick the right weather and time

    Overcast or two hours past sunrise gives the most even light. Avoid wind, rain, and harsh shadows.
