if you have a drone or have a friend with one, it's pretty easy to do this with aerial photogrammetry. Something like dronedeploy.com makes this very easy with a DJI drone. Draw the area you want to capture as a polygon on google maps in DroneDeploy, deploy the drone, off it goes, takes the photos and lands without you needing to do anything. Then just upload the photos, and you get a 3d model processed on their servers an hour or so later.
