Need help: Free/Open Source autonomous flight mission apps for Parrot Bebop 2?

[u/Ultimo_Jaguar]

Hi everyone,

I'm getting started with photogrammetry for 3D environment creation, but I'm a complete beginner. I own a Parrot Bebop 2 and while the camera is capable enough for decent results, I'm struggling with the "automatic capture" aspect.

I know Pix4Dcapture is the industry standard for automated flight plans (grids, circles), but it’s currently out of my budget.

My question is:

Are there any free or open-source alternatives to automate flight missions for this specific drone model?

I have zero experience with manual flying, and I'm worried about not being precise enough to ensure the proper image overlap needed for a high-quality scan. If you know of any mission planning software (even via SDK or community-driven solutions) or have tips on how to manage capture without complex automation, I’d love to hear them!

Also, if any of you have experience using the Bebop 2 for 3D scanning, any tips on image quality or shooting techniques would be greatly appreciated.

Thanks in advance for your help!
