I have taken the images carefully with lots of overlaps, especially of the high seat itself at a far distance.
When I move in, I can’t take images from all sides, of course.
But the fact that RC creates only the seat doesn’t seem right to me.
Always strive to use the lowest ISO value your camera can do.
It minimizes noise.
To fight blurriness use either a tripod or a monopod to stabilize the camera where possible.
If you can connect a remote trigger to the camera, use it too. It prevents camera shake from pressing buttons on it.
Hi tw2016
in the images circled RED I can clearly see panoramic shots, and I think there are more of them… they are useless for photogramemtry…
the GREEN lines mean where you need to take images, say 30-50 images per round… you need to move closer and closer to the subject, not with so big jumps from each other, best if it is under 1/3 of the distance…
I think in this case it better just ask for new feature without any comparison.
But don’t worry, i also test your dataset in “other” software with the same result. So problem what i wrote (ISO noise, motion blur, DOF) and what Wishgranter draw (your cameras vs. how you should shoot such objects) for you is a main problem why you can’t have good result in most modern photogrammetry software.
As for settings:
I set bigger Feature per Image count, Reprojection error (around 4 or 5 pixels), Set image overlap to Low, And set bigger Preselector Features (about 1/2 of Feature count) in Advanced settings and Detector Sensitivity to High.
This was allow detect features that too weak (because of reason i wrote) and made “draft” traingulation of cameras. Later you can lower reprojection error delete all components except biggest, and run align again. This will allow refine alignment. But lower than 1px error you again lost most of camera positions. And this mean that mesh from such 1px error aligned cameras will have too much artifacts. Try imagine 1px in image can be 1-10 cm on real object, Every pixel - every 1-10 cm can be in random place.

I would counter, in a small way, the use of panoramic shots. If you’re trying to capture as much as possible, especially in a closed space, panoramics can be essential for a good workflow. I still hone in the way Wishgranter explains above on items of focus, which is what you absolutely need to for this example as you’re trying to get a single entity scanned, but if you were to get a whole section of the woods to explore before you hit that roost, I’d be using 15 to 20 degree rotations at about 8 locations around the eventual exploration box. Important stuff if your intent is to explore a large model for things like VR, not so much if you’re focusing on a handful of things only.
And while they really fill up unfocused parts of a large scene well, you need to be very careful on where you put them for best results. The first few iterations were horrible, but they really help me compose a large inside scene when I plan a shoot out.
