WayPoint Mission within a building not around

[Eko]

I need to make a photogrammetry work "inside" a building (say a gallery) which is almost a square to rectangle in shape. Size of each wall is around 20-25 meters. The aim is to get the details of the walls. Is there a better way other than constructing a Circular WayPoints mission with camera set to zero degrees and the POIs are defined on the surfaces of the walls? (Note that, it is quite difficult to define a circle with a little radius, the flight speed, the overlaps etc.)

Is it possible to employ a Circular HyperLapse action? Thanks for your your advises.

Why not use a 3-D building scanner?

don't have it.

don't have it.

... is it the same for the GPS reception?

Waypoint missions rely on that.

Surely it would be easier to set up a camera on a tripod in the centre of the room. Fix the focal length, then take pictures as you would for a panorama. If you’re being really clever you could mount the camera and lens so that the pivot of the tripod was at the entrance pupil of the lens so you’d remove any parallax errors.

iPhone 13 has a built-in lidar scanner. Failing that, you can do just as good a job with a regular camera - overlapping stills run through SFM (Structure From Motion) software like 3DF ZEPHYR... but you have to keep the camera a set and even distance from all four walls as you work round the interior space.

Thank you for the feedback, I know that I have those options; but I would prefer doing something with the mini 4 pro.

What would you suggest if the are area of the gallery was far larger, requiring the use of a drone?

Your kind input and suggestions will be helpful. Thank you.

Manual flying. Most likely not going to have appropriate GPS reception for automated modes inside a hall.
