Border between areas with differing distances of the cameras to the object

    Hello,

    Your problem is most probably caused by the incorrect alignment of the images. If there is a missing coverage of photos (something like gap between camera angles), then this area can be shifted during alignment. I would suggest you to use RC inspection tool to see the connections among cameras. You can find it in the ALIGNMENT – Analyze – Inspect. If there is a few or almost none connections among images in that part (connections are displayed as lines between cameras), then I would recommend you to add more images that covers these areas.

    Sorry Zuzana - you're right about Help - but there is contradiction.

    In http://janebeecr.blogspot.co.uk/2017/05/how-to-never-miss-spot-again-with.html

    "an example where there is not enough matches between two pictures. As you can see the line between the images is yellow" (yellow being part way to red)

    "When you use inspection tool, color of the lines represents the amount of matches between two cameras. The more, the better. When the web is really dense and all the lines are same color of blue, that means that you have enough images, that you have covered whole object perfectly and you will get the best possible result."

    Looks like Jane thinks blue is best.

    So does https://support.capturingreality.com/hc/en-us/articles/115001552532-Quality-assessment

    "A web of blue lines should appear (see the picture below). The colour scale of the Inspection tool is blue to red. The more red, the worse. On the other hand, the closer to blue colour, the better."

    I want to add that a line is nor guarantee for a flawless alignment though.

    The TO indicated another source for the problem, which is the difference in distance. I suspect the jumps were to big for RC to match the cloe and far ones properly.

    Also, does the TO (I refuse to adress people with numbers  :-) use a rig to capture the person or a single camera? Because if the latter is true, it will never be perfect.

    If you used only one camera, the results cannot be perfect due to small movement that is inevitable. It also seems to me that you took almost too many fotos in one line - this can be counterproductive. About turntables, there are already many helpful thread here in the forum. RC is no different than other programs - it just doesn't have an internal masking tool.

    Tom, I use it as Thread Opener, that's what I usually see in other forums - OP is the post itself, not the person!  :-)

    Oh these young people with their funny internet talk!        BTW I'm old enough to be able to say that...  ;-)

    It never seems to be said, and I only found out indirectly, the very important info that in Inspect, blue lines indicate good (many) connections between cameras, red poor (few) connections, and the other colours in between. This should be spelled out in Help.

    Hello Tom,

    The edge color is blue-to-red (Jet color scale) indicating how strong an edge is - actually more features, more red.

    You can find it in the Help section - Inspectiol Tool.

    Curious - what does TO stand for? To me he/she is OP (Original Post).

    Daniel). Thank you for the answers. The lines are blue, but I used a single camera. Can CR align photos when the camera is fixed (lazy susan turntable)?

    At least we lived all the high hopes of what the interenet, www etc might have been, but got captured and subverted (so far).
