A mesh is not created in the point cloud.

After alignment, a point cloud exists, but when creating a mesh, a mesh is not created for the point.
Other objects didn’t do this, but the same thing happens. I tried reducing the picture and trying other methods, but it’s the same.


Hi jiiinnssee,
this seems like a result of not good alignment. Is this crack real on the wheelbarrow?

As its plate is quite thin, you need to have a good alignment of the images. Have you captured the images just around the wheelbarrow? If so try to take some images from the inside and also use some control points around empty areas.
Also, is it possible that those pars are shiny?

Hi @OndrejTrhan
There are no cracks in the cart, and it is not made of shiny material. The number of photos taken for the cart is about 700, and I tried using control points in empty space, but it is similar.

If there are no those crack it is a result of wrongly aligned images. You need to capture more images which will follow the shape of the wheelbarrow with at least 75% overlap between images. The inner parts should be captured, too. And you can try different distances from the object.
As the plate is really thin, it could be problematic to capture it properly.

There are 700 images taken very closely with 75 overlaps.
And the image taken from above is actually better formed when the image is reduced.
When taken upside down, the mesh is well formed without any holes.
But why do holes appear when two images are masked, aligned, and then formed into a mesh?

Yes, but your images don’t seem to be taken in regular pattern but more in random order. Also, some images seems to be taken from one spot.
Like, there are not images which are following the object’s shape:

Yes, the upside down wheelbarrow is modelled correctly, as there is no inside part of the plate. The plate is really thin in this case and if the alignment is not precise, the holes are created.

Basically, the surfaces are interrupting each other, which results as hole in the mesh.

If it was not created due to filming in a regular pattern, random order, or not following the shape of the object, I think it is correct that the previous recordings were not formed. However, if you look at the previous recordings, they were formed.

If it is because it is thin, will it be possible to form it if I use control points on the inside and outside of the plate that cannot be formed?

This is not from images (as you are using work filming/recording and not capturing)? I am sorry, but I don’t see regular pattern/shape following on your print screens. Do you mean this image?

It should help, but still I would use more images captured from different distances and also from the inside of the wheelbarrow.

Sorry the translation wasn’t good
It was not a recording.
What I want to say is that I shot the previous objects in the same way, but the objects were formed.
