General / Heights in agisoft viewer
« on: April 14, 2021, 11:44:07 AM »
A question about the Agisoft viewer.

I have created a project with my own height system. It is the UTM coordinate system with DHHN2016 heights for Germany. When I output this project as a tiled model, the ellipsoid heights appear in the viewer, my DHHN2016 heights are gone. Is that what you intended?

And if so, how can I then output the project with the correct heights for me and the client in the DHHN2016 format?

Bug Reports / Photoassignment Orthophoto is bad
« on: August 28, 2020, 11:03:30 AM »
Because I don't get an answer in the general forum, I'll post my request here again:


I would ask you to check the image assignment for the orthophotos again.

The optimal photo of the surface is not assigned, as can easily be seen from the attached example. Example 1 is the automatic Ortophoto, example 2 the post-processed version.

In this example, all photos had to be exchanged to get an acceptable surface.

I have often pointed out this problem without any change on the part of agisoft. I like to work with Agisoft a lot, but I have to exchange hundreds of photos for every project, which in the long run becomes too much for me and is unproductive for our office.

I am happy to help and offer my support.

Dieter



I may have found the solution.

The previous examples are cylindrical developments.

It looks like in this case the software determines the ranks of the images in exactly the opposite way.

I noticed this when I exchanged the pictures, Rank 1 means good for normal orthophotos, for my cylindrical developments it means bad.

That means the worst pictures are used for the orthophoto, very bad.

Dear Agisoft team, please check this !!

Feature Requests / detailed orthofotos
« on: May 20, 2020, 09:34:50 AM »
Hi,

We very often process large orthophotos and are not always satisfied with the assignment of the images.

Please note the attached document, which shows a typical situation that often occurs.

Green is the object to be measured, blue is the individual photos taken, red is the direction of the orthophoto.

Metashape uses the images of "2" in the side areas because they are parallel to the direction of the orthophoto.

The photos from "1" would deliver much better results because they are closer to the object, have a vertical direction of exposure to the object and are therefore sharper than the photos from "2".

As a result, our office has a considerable additional effort to create "better" orthophotos from the orthophotos from Metashape. Hundreds of image areas are changed for better single shots.

As a solution, I could set priorities that the user could freely define. My priority list would then be:

1) Angle to the object (vertical recording direction if possible)

2) Distance to the object (photos as detailed as possible)

3) Fill the remaining areas with other photos that do not meet 1 and 2 to fill the areas.

Are there ways to do this or are there other solutions for "better" orthophotos?

Thanks
Dieter

General / Build normals in metashape
« on: April 16, 2020, 03:13:40 PM »
Hi,

are there any "hidden" options to build the Point Cloud normals?

I build the normals always in cloudcompare because they are better then in metashape.

In the future i want to build them in Metashape, therefore my question.


Thanks

Bug Reports / imort E57
« on: August 14, 2019, 12:36:26 PM »
When reading an e57 file from Recap, the coordinates contained in the file are ignored in agisoft.
Exporting from recap and reading in pts format works.

General / Safety message
« on: August 08, 2019, 12:00:43 PM »
It would be very beneficial if a security prompt ALWAYS appeared when overwriting data.

If I create an ortho image and an already existing one is active, it will be overwritten without a message. >:(

General / Questions about 1.5.2
« on: March 26, 2019, 12:11:05 PM »
Hello,

maybe someone can explain to me what the option Mild-Filtering means when creating the point cloud and creating the mesh.

The infos is always mild-filtering, I can set this somewhere or is the default?

Under which conditions can the deep images be reused?

Are the memory problems with the option Quality = high or Ultra solved in the version 1.5.2?

These are all questions that keep me in time, because everything has to be tried out, like trial and error.

A little more info on the general user status of the software would be very nice.

Thanks
Dieter

General / Reuse dephmaps
« on: February 21, 2019, 04:09:30 PM »
Hello,

I work with the settings "reuse depth maps on".

First, I calculate the point cloud, so the depth maps are stored in the project. Then I would like to reuse the depth maps for the mesh calculation. This does not work for me. The depth maps are always recalculated. The setting for the depth images is "high".

What am I doing wrong?

Metashape 1.5.1

Thank you

General / Questions Metashape 1.51
« on: February 06, 2019, 12:21:28 PM »
Hello,

First of all thank you for the new version 1.51. The results of the new meshing method are ingenious. Likewise, the calculation time has decreased enormously.


I have a few Questions About the new Versions:

- I still have problems performing a meshing of laser scanning clouds. I have described these issues in the thread pre-release. Is there any evidence?

- From Metashape, it is no longer possible for me to display tiled models in the viewer. Is there any evidence?

- Is it correct that a complete calculation is started again for the point cloud generation, or can the generation of the point cloud be somehow shortened after the mesh has been build?

- Is it possible to create the point cloud from the finished mesh? It would suffice me for the accuracy, if I Could lay 5000000 points on the surface.



Thanks for the answers
Dieter

General / Not the best Pictures used in Orthofoto
« on: September 18, 2018, 10:52:29 AM »
Hello,
it often happens that agisoft uses the wrong (worse) photos on the ortho-image. In the attached image, the area can be captured with a single image. Agisoft puts a lot of small pieces from different pictures in this area.

I would like to have an order in which Agisoft uses the images.

1.) Distance to the object
 (The smaller the distance, the better (sharper) the pictures)

2.) Angle to the object
(the more orthogonal the picture was taken to the object, the better the pictures)

In the current state of the software, these orders are underused.
As a result, 200 image areas have to be exchanged in a church facade, which is very time-consuming.
Is it because in the example vertical walls are shown in the orthophoto, which is not the standard in contrast to the horizontal illustration?
If so, can the sequences I have mentioned be used for vertical mappings?

My bad English results from Google translator .......

Thank you.
Dieter

General / Tiled Modell crash
« on: April 12, 2018, 07:16:00 PM »
Hi,

i can't build a tiled Modell in the newest Version. Every Modell chrashed and i see only the Crash Reporter.

I've tried several Models, always the same !?

Any hints?

General / Orthomosaik with cylindrial projection
« on: January 18, 2018, 02:53:07 PM »
Hi,

i want to unwrap a surface with the function orthomosaic with cylindrial projection (See attachment).

My axis Points are Abwicklung 1 and Abwicklung 2, my Point on the surface (origin Point) is Abwicklung 3.

It seems the unwrapped orthomosaic is projected on the whole cylinder !?

Is there a Workaround for my Problem?

Thanks

General / Question about meshing
« on: August 17, 2016, 07:28:16 PM »
Hi to all.

Picture 1 : point cloud with 131028691 points.
The meshing was performed over the whole point cloud.

Picture 2 : a detail from the point cloud with 363000 Points.
The meshing was done with the same parameters as in the first Picture.

The result is much worse.


The ratio of points to triangles in both cases is 5 : 1

How can i archive the same result as in Picture 2 with the whole Pointcloud?
In my opinion , the result should be the same!?


Produced with google translator :(

Thanks
Dieter
