[Bug 712978] Re: Multi-image control point generation.

 

The "moving objects" is less of a problem. The biggest problem is that
on some images all the automatically found control points are in the
grass near the photographer. Any small parallax errors will make the
horizon look completely crooked. Some well-placed controlpoints near the
horizon usually makes things a lot better.

Title:
  Multi-image control point generation.

Status in Hugin - Panorama Tools GUI:
  Triaged

Bug description:
  The automatic control point generation is reasonable. It usually gives
  me a layout that is quite reasonable. However, then I like to finetune
  the control points so that they are further apart, and not on moving
  objects.

  I'm currently working on a HDR pano. So images 3-4-5 are different
  exposures of almost the same scene, and they overlap with 6-7-8 and
  with 0-1-2.

  What I find myself doing is, finding a suitable point in image 3, then
  creating a controlpoint with image 4, then with 5, then with 6, then 7
  then 8. This would be much more "comfortable" if more of this could be
  done automatically.

  A new controlpoint editor mode could be written: Show one image
  "large" on the left. Once I click on a point in this image, the
  current layout is consulted and the images that overlap this point are
  selected. Those are shown in a grid on the right half of the screen.
  around each corresponding point (simple linear controlpoint
  transformations will probably suffice as with the current controlpoint
  guesser) the auto-find and auto-finetune will search for similar
  points. Now we have a set of 6 images with ONE controlpoint. We can
  add all 5+4+3+2+1 = 15 control points at once! For verification, the
  images on the right are zoomed in on the controlpoint. Or the zooming
  happens when you hover over the image.
