Alignement errors...

[Yoruk]

I made some experiments with two sets of pictures. It works great but I have some alignment errors for a couple of pictures.

How can I remove them ? I tried to select them directly on the 3d view (but I think I can't). I also tried to find them in the explorer view on the left, but a right clic / delete seems to leave them on the screen.

I am doing something wrong ?

You can doubleclick any camera in the workspace to directly zoom to that camera point of view. By doing so, the camera will be automatically highlighted in the bottom view. You can hover if you need to see the name. Then, simply remove the desired camera from the camera panel list by right clicking and then selecting "remove". Please note that you'll need to re-compute any object you may have already computed after the SfM phase (so all dense clouds, mesh, and textured mesh). You won't lose existing objects, but of course, they will still be the same, with information of the wrong camera.

Got it.

It looks like that I can't remove the first "sparse point cloud". So in order to compute my model without my wrong cameras, should I immediately compute a "dense point cloud" or should I have to do again a "sparse point cloud" ?

[Andrea Alessi]

You can't remove the sparse cloud as it is the root of the project.

You can simply remove the cameras and the proceed

For example:

Sparse cloud - 10 photos
Dense cloud 1 ---> made with the above sparse cloud

Then you remove 1 camera

Sparse cloud -> now has 9 photos
Dense cloud 1 -> still untouched, made with 9 + 1 wrong camera

Then generate a new dense cloud

Sparse cloud -> now still has 9 photos
Dense cloud 1 -> still untouched, made with 9 + 1 wrong camera
Dense cloud 2 -> made only with the original 9 photos

Then you can generate a mesh starting from your correct dense cloud 2, and so on

Ok I understand.

Well the process works fine, but the "legs" of my models are a bit "skinny". What can I do to improve the quality here ? Take more pictures ? Adjust some parameters ? I use mostly default parameters everywhere.

Attached are two pictures : final 3d model and original picture.

Hi Yoruk,

using high details may improve it. If you used the same setup you showed me before, you are also quite far from the subject, so i would also take a few closeup photos.
