Oil tank modelling

we want to model an oil tank, diameter +/- 70m. Inside and outside. What strategy is suggested to capture the inside successfully (open from above) and be able to match it with the outside.

For exterior I will fly at approx 40m with camera at 45deg.

Also a grid flight at same height.


Hi Simon,

If the inside walls of the tank are visible from above and the texture is not uniform we would suggest a double grid mission. Regarding the exterior flight it is recommended to take one image every 5-10 degrees to ensure enough overlap, depending on the size of the object and distance to it. Shorter distance and larger objects require images every less degrees.

You can find more information on flight plans depending on object reconstruction here:
