Make sure you have some vertical CPs in several areas of the room. I'd try to optimize the horizontal row first and deselect all others. Maybe in your case I would try to first of all only generate CPs for those images that were shot with p=0. Only select those in the lens tab and click the 'generate control points' button. As a first step I mostly only optimize for y and v, after that I add p, then also r. From time to time have a look at the CP table to identify bad CPs. Have a look at the preview to see if some bad CPs lead to freaky results (you could always reset the miscalculated values in the lens tab if something very strange happens). As soon as your first row is sort of stable, add the other frames one row after the other... While checking for bad CPs I often enough see areas that are worth adding some CPs manually. Even if you have once calculated a, b and c for your lens: do it again for this project. I mostly deselect y, p and r and then optimize first v and b, after that a and c. Next, optimize also for shift (d and e, but not together). Now again optimize for y and v, after that add p, then also r. It's not really a simplified 'point and shoot' technique but it works for me. >>> i'm using a canon >>> 5d body, at 24mm, the hfov is 53 degrees, so i think i am ok with >>> overlap. i initially tried taking shots at 20 degree steps, however 9 or 10 images in the center row should be enough to get a 25 to 30 % overlap. This should suffice for rooms unless they consist of mostly huge white walls. The upper and lower rows will surely need less frames, just simulate that in hugin with dummy images (with a frame so you can see the ca. amount of overlap in the preview). Just another idea: try a different matrix of shots that have two rows at the horizon: one tilted up about 25-30 deg., the other tilted down the same amount. That way you might need about 4 rows the full sphere: 9x p=30 deg. 9x p=-30 deg. 6x p=80 deg. 6x p=-80 deg. -> it should work with just 30 images :-) Carl --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
