I’ve just found this toolkit and it looks great.
I have, however, what may be a stupid question: is it possible to generate ortho’s / pointclouds without true aerial images? What are the limitations?
My current use case is a small valley of a few acres: Walking around at the highest point with my iphone I’m able to photograph a sizeable portion of the valley. What’s the best chance of getting a point cloud from these? If I walked to the next highest point on the other side and collected images, could those be stitched or is the change in orientation too extreme?
