Feature Requests / Preview image for project

« on: December 04, 2023, 01:07:59 AM »

Hello!

I have a lot of little test projects and after a while, I get a folder with say,.. 50
old tests, and it is sometimes hard to remember what they all contain. So apart
from documenting this in a readme file, lately I find myself saving screenshots
from the model. It would be nice if one could click on such an image, and then
open up metashape with the corresponding model. Probably in linux i could
make some script to do this but maybe it would be a nice feature to have
in some form..

thnx

General / Insta360 building scan

« on: December 02, 2023, 02:37:15 AM »

hello!

I'm trying to scan a building using an insta360 One RS 1-inch 360 edition camera.
This has 2 fisheye lenses, and I'm using images from the front lens, taken at a height
of 3 meters, and at a distance of 2 to 3 meters apart. See one of
the example images below. (original resolution is higher). I calibrated the lens
using metashape's camera calibration tool. This works but the tool seems to skip
images, in which the calibration target comes right up to the edge of the image.
The target is only detected when it is more or less in the center of the image. The resulting
model captures the general shape of the building quite nicely, but the details look
a bit .. mangled. See attached image and this sketchfab model:

Do you think this is a limitation of this type of lens (not as good as some dslr lenses)
or can the model be improved upon?

thnx !

Feature Requests / 'Wallk through room' style navigation

« on: November 16, 2023, 02:30:07 PM »

see

https://3rl.io/hallwyl

This type of navigation would be nice to have, to kind of 'walk through' a model, eg a scanned room,
like implemented in the above web viewer:

  * move trackball forward / backward / left / right (w / a / s / d keys) for 'walking'
  * pan view left / right / up / down by moving the mouse, while keeping the horizon level and position unchanged

there could be an option added to move the trackball up and down with the keys. .....

For scanned objects, the current style of navigation is very convenient but it is less nice to use
to look around in a scanned room . This alternative navigation style like is implemented in the website
would be nicer to do that...

thnx !

Feature Requests / Move trackball perpendicular to screen

« on: November 07, 2023, 02:47:50 PM »

Hello!

The origin of rotation ('trackball') can be moved through the model using the right mouse key, it then moves parallel to the screen if I see it correctly. It would be nice if it could also be moved perpendicular to the screen. Maybe with shift-right mouse button or somehting? This would be convenient when 'moving' inside a scanned room. Right now we can do ctrl-mousewheel, but that only zooms the view...

thnx.

Bug Reports / Banding in texture when using multiple exposures

« on: November 07, 2023, 02:22:47 PM »

Hello!

I'm making scans of a room in which the light varies a lot. When I use different exposures for different images (aperture priority mode) I see banding the the texture. I don't see the banding when I use the same aperture and shutter time for all images. The problem is present in my version 2.0.3 of metashape and also in 2.1.0. In an older version I still have 1.8.1 however, the texture based on multiple exposure images looks fine. See attachments.

General / Circular bands in texture

« on: November 06, 2023, 10:14:50 PM »

 
hello

I'm doing some test scans of a room and sometimes I see these circular bands appear in the texture. Just now I repeated the 'build texture' step and the bands seem to be gone (see attachments). Luckily I uploaded the 'banded' model to sketchfab so you can still view it:

bands:
https://sketchfab.com/3d-models/corridor-test-312d91081890457db86e7f00c2e02367

no bands:
https://sketchfab.com/3d-models/corridor-test-2-f2a395148dfb4b8e94ec1143547c55f5

At first I thought it had to do with using images with multiple exposures. This resulted in the banded texture. I then used the manual setting on the camera and took all the images with the same settings, then the bands were gone. But as said, I just ran the build texture step again on the images with multiple different exposures (I used a single aperture and automatic exposure time) but now the circles are also gone..

So I was wondering if this could be a bug, or did I forget to change some setting? I used the 'mosaic' setting in the texture dialog in both cases as far as I know.....

thnx!

General / Move trackball (or model) perpendicular to screen

« on: January 23, 2022, 04:40:08 PM »

Hello!

The origin of rotation ('trackball') can be moved using the right mouse key, it then moves parallel to the screen if I see it correctly. Is it also possible to move it perpendicular to the screen? This would be convenient when 'moving' inside a scanned room. On sketchfab, this happens when double clicking the screen I think.

thnx.

General / View inside closed object (eg a room) from a distance

« on: January 17, 2022, 06:09:00 PM »

Hello!

I'm trying to scan a room using metashape . The first results look very promising:

https://sketchfab.com/3d-models/roomtest-bb3c9fbdc72a42c8b7d803e00c050f6f

This scan comprises only part of the room: the floor and 2 walls. So one can easily
zoom out to get an overview. However, if the scan would include all the walls, one would
at a certain moment... move through the walls when zooming out. Is there some way to
create view of an intersection of the object ie, leaving out on of the walls or sides, to
get a zoomed out view from a distance?

kind regards

General / No texture on filled holes

« on: January 15, 2022, 12:54:48 AM »

Hello!

I'm trying to make a model of this box (first one)

https://sketchfab.com/vanjos/models

When I use 'medium' quality settings in all steps from the workflow menu, there is a hole in the shadow side of the box (image 1). I was able to fill it with 'fill holes' from the tools menu. But then the filled hole has no texture (image 2). Building the texture again doesn't solve the problem. Why? There seems to be enough information in the photos: if I run all the steps in the workflow with 'lowest' quality settings, there is no hole and also the shaded side of the box has a more or less convincing texture.  (image 3) What can I do to get the texture in the filled hole?

kind regards

PS I just tried the same procedure, using 'high' quality settings, and the hole is even bigger....
