General / Re: reset selected cameras removes tie points

« on: April 08, 2021, 01:06:16 PM »

Tie points are matched feature points. If you reset some cameras alignment, the tie points will be removed form the 3D scene as the cameras are no longer located in the 3D scene. However key points are still on your photos so you can use align selected cameras to bring them back to the 3D scene hopefully in a better location. It should take but just seconds to re-align cameras that where reset.

Hi, you need to learn how to use "region". Try to reset region found under Model/transform region or in the region button dropdown.
Kind regards.

If you need some training, I suggest you to take our Agisoft endorsed course. https://accupixel.co.uk/metashape-training-courses/

This (drawing on photos) is something that can be done since long time ago. I don't understand what you mean. Can you clarify your question.

Exporting profile as 3d dxf is supposed to produce exactly what you got. a 3d polyline. If you want rather to export the profile plot with axis, labels, etc. I'm affraid you need to export the profile as an image and paste it wherever you need it in your drawing, but it will not be a vector graphic.

General / Re: How does Assign Images works ?

« on: February 23, 2021, 09:53:02 PM »

but the best fit image will be assigned automatically

There is something that should be clarified. This automation takes for reference the location of first vertex you enter when you draw the patch.
I think developers should rather offer a few best choices according to:
1. Camera closer to the centre of mass of the patch (no to the first vertex), and closest to the principal point of suitable cameras.
2. Best orientation. best fit plane on patch vertices could be used to sort photos according to angle with respect to the patch.
3. Content awareness. In a more advanced approach, the software should be able to skip photos with pixels that are inconsistent between overlapping photos. That would help to remove moving vehicles, for example. Actually I wonder IF Such smart filter could not be used during orthomosaic creation as well to automatically remove people, cars, birds, branches, etc.

General / Re: New 1.7 Cylindrical DEM/Ortho Issues

« on: January 18, 2021, 04:17:25 PM »

Hello JRMertes,

For cylindrical orthomosaic generation you should also select the mesh source, as it currently doesn't work for DEM source option in this mode.

Hello, Alexey
I have reported this option not working more than a year ago. You also answered "currently..." and that made me think it was a temporary issue... I have seen quite a number of updates and fixes since, but this inability remains unsolved. Why? I remember it worked well once, so I wonder what it takes so long this fix to come. IN the meantime the option should be disabled to warn user to not waste time.
Best regards.

Happy new Metashape version!
Exclude stationary points... sounds like a great help for rotary table scans, doesn't it?

Yes:
Create a polygon  and set it as outer boundary (right click on it). This will apply to exported orthomosaic or DEM. (You can also use inner boundaries to create void areas as well)

Can be done by masking, but a strighter method would be welcome.

Feature Requests / Re: Feature Request : Copy Cameras

« on: December 01, 2020, 04:17:11 AM »

Not the answer to your wishes and takes more time, but, what if you duplicate chunk A, then move desired photos from copy of Chunk A to chunk B and then delete copy of chunk A....?
This way you would get "move to" working as "copy to".

Right click on one photo and choose change path. then browse to the new location, select the lost photo and apply to... your choice.

General / Re: "Keep keypoints" confusion - not working as expected

« on: November 19, 2020, 03:05:03 AM »

what does "reset alignment" in your step 3 mean? and why do you do so if you are trying incremental alignment... if you reset current alignment, then you are aligning from scratch... aren't you?

General / Re: "Keep keypoints" confusion - not working as expected

« on: November 15, 2020, 11:15:36 PM »

Hello, Andyroo:
I think you are doing the opposite as explained by Alexey.
You should not reset existing alignment and to do so you should make sure to unckeck=disable "reset current alignment".

General / Re: Discrete measurements of checkpoints in Metashape

« on: November 08, 2020, 09:03:18 PM »

Hello, Samantha:
I cant fully explain your error without further analysing your dataset and fully understanding your steps. when it comes tho the las question, the 3d error of a check point corresponds to the differences between input and estimated coordinates and to give this error in a single number they are just summarized as a quadratic mean

General / Re: Tabulated error in Metashape

« on: November 08, 2020, 08:43:16 PM »

Hello Samantha:
If you select one gcp and right click, you will see "info" option, that will list pixel errors for each projection.
I wonder if his is what you want. This will allow you to find images where projections (manual green  or automated blue) are not-so-well placed. Be aware that this error may be a sign of bad orientation of a given photo where GCP pixel errors are high even they look well placed.

Best regards.
