Align Images not using all photos

    Hi david,

    did you try it with standard settings yet? Yours are adjusted in some points....

    Otherwise a few sample images would be very helpful or at least a description (modern glass, ancient masonry etc).

    In my experience it could be quicker and also, if shot properly, align most of the images.

    Have you done this before, in RC or other software?

    Hi David,

    You did not mention if you edited RAW files or JPG files. In the case of using JPGs, you will likely get a more successful alignment without any edits. Editing JPGs can result in pixels that are too different in consecutive images that RC rejects them as viable tie-points.

    You can also change the alignment setting for the 'Image overlap'. If you set this value to 'Low' then RC will use a larger portion of each image to find matching tie-points. Increasing this from low to medium or high can decrease processing time if your overlap is good but it can mean that some oblique images fail to match.

    You can also try grouping all the images together so that they share the same camera calibration. You can do this by clicking on 'Images' in the left sidebar. A new menu will pop-up with white buttons, click on 'Group'.

    To answer a few questions, I, at the time was using a more vintage lens, and the subjects I have tried vary from concrete facade buildings to latex props. Everything so far on the Sony, I have shot in RAW, then exported to JPEG, which is what I imported into reality capture. I have also tried shooting video on a Pixel 3 cell phone to similar results.

    Going forward, I have reset the settings (Not sure where I saw it, but I saw a post that recommended the settings I had it on previously) and I will try running it with low image alignment and let you know.

     

    Thank you for the responses!

    Out of curiosity, is it "critical" critical that the photos themselves are captured in a circle? When I photographed the building, I walked up and down the sidewalk parallel and perpendicular to the building (three passes: facing the building, and at both 45 degrees to the building). The shape of the street prevented me from being able to do the traditionally recommended onion skin technique.

    Dear david,

    Is this lens anything unusual? You could try out different distortion models, maybe that will help.

    The circle is the ideal approach but mostly works only for smaller objects and it's very often not possible for complex large structures like buildings. It is more important to cover surfaces at more or less perpendicular angles and then connect those areas. No sample images?
