Gimbal or no gimbal for aerial mapping

There is no need to be exactly vertical for the camera axis. The mapping post processing phase goes through 3D reconstruction first, and all is needed is a regular pattern of pictures with good overlap. No matter if there is a +/- 10° pitch or roll.

I started my activity with a camera directly fixed under my Iris+ belly, and never had any issue for mapping. I added a 2D gimbal on my second bigger machine, but it is not for stabilization. It is to force a pitch or roll angle for good 3D reconstruction. Because finally angled views are better for this purpose than strictly vertical view.

So for mapping (house roof only is good): no gimbal.

For 3D reconstruction (need also house walls) : gimbal
