Looks great, thank you so so much! In the future, should I optimize lens parameters before or after aligning the images? Also, I see you left X, Y and Z unchecked for a particular image and checked all parameters for the anchor image too, can you explain the rationale? I though I was supposed to leave the anchor image unchecked. Was that the last one to be optimized?
After a lot of trial and error, my workflow was to: - Import all images and detect control points - Clean obviously bad control points (normally when there's only 5 or so in images that don't overlap) - Select only one image at a time, start with XYZ, add Yaw, Pitch and Roll, then plane yaw and pitch - If the error was under 1unit, move on, else try a different order for the parameters, another neighboring image, or review CPs After all images were aligned, I would go to the Move/Drag tab and try to get it level. Throughout the process the alignment looked good but the map was very skewed. Is there a better way of doing so (like straighten/keystone in Capture One or PS), or is this fixed by the line CPs?

Looking at your version: I think it is harmful to optimise plane pitch and yaw here; the first lens parameters should be optimised (eg a and b); given that there is a grid it is helpful and very easy to define a few horizontal and vertical lines; you can remove many control points that are in areas of low contrast, especially the water, because you can't trust them. However, there are limits to what one can expect as the map is not completely flat. cheers, lukas wirz On 02/07/2025 23:42, Martim Passos wrote: > Hi, I'm stitching non-panoramic images of a map and, after reading the flat > scan tutorial and some threads here about doing one or two images at a > time, parameter optimization order, etc, I achieved what I believe to be a > decent result.
