Feature Requests / Add field list when importing references
« on: June 06, 2023, 11:01:18 AM »

When dealing with a csv with many columns, the process of assigning the number of the column for each field is painful. It would be a delight to have a list widget to select them or, at least, have the column's number in the header row.


Feature Requests / Extend Reduce overlap to DEM for ortho production
« on: August 06, 2021, 11:50:47 AM »

Up to now, the reduce overlaps feature only works with a generated 3D mesh as a basis, not a DEM. For us it would be useful to accelerate the production of orthophotography where we would discard all the axis but the nadir.

If we do it with the generated mesh and the nadir images, the overlap algorithm will keep a bigger amount of images to cover the vertical faces which are not needed for the ortho end product. Basing it on a DEM would improve the rate of reduction and speed up the next steps of processing.


Feature Requests / Update gdal export
« on: December 09, 2020, 10:53:24 AM »
Hi, with GDAL 3.2 it is now possible to benefit from
- multithreading when doing an tiff export with a JPEG compression
- multithreading when computing the overviews
- faster deflate compression/decompression through libdeflate

these features would speed up the export of orthomosaïcs


Feature Requests / Add AVIF support
« on: September 29, 2020, 03:42:29 PM »

We would appreciate if Agisoft could extend its support to the AVIF format for imagery, we are considering it for our aerial and drone pictures instead of JP2 and JPEG because it already have a wider application support (Chrome, Firefox, Windows 10) than the first and a better compression rate/quality than the second.

A few benchmarks :

For those of us having to manage a few millions jpeg, this format is interesting :)

Hi everyone,

Does anybody (or agisoft) has a process using a LIDAR dataset as ground source during the stages ? Metashape allows to import/merge lidar points but I did not found how to make use of the ground classification to ponderate the reconstruction.


General / Is ECC RAM necesarry ?
« on: February 17, 2020, 02:31:40 PM »

We are planning a new workstation purchase and the choice of the graphic card is the main point, the difference between a Quadro RTX 6000 and a Titan RTX is mainly about the overpriced ECC memory (the diff in frequency and bandwidth is marginal).

Is ECC crucial for Metashape ? Would its absence downgrade the reliability of the outputs ?

Feature Requests / Add covariance matrix export
« on: August 09, 2019, 10:15:06 AM »

It would be great to export the co-variance matrix to a raster grid or as the scalar field of a point cloud, this would allow this information to be used with other GIS layers. Adding it to the report would be cool too !

Feature Requests / Add surface constraints
« on: August 09, 2019, 10:07:34 AM »
Several photogrammetry softwares such as Photomesh or ContextCapture offer the possibility to use a a polygon source to add constraints to the mesh reconstruction, this feature is mostly used to flatten water surfaces to avoid geometrical artifacts (ripples, pits, etc.).

This feature is great when dealing with a large project, correcting by hand (deleting and filling back) is too time consuming and could be avoided by the use of pre existant digitized polygons and their elevation data.

General / Flattening water surfaces
« on: August 06, 2019, 10:45:29 AM »

Is there a way to flatten water surfaces reconstruction using a polygon source ?

Several photogrammetry softwares such as Photomesh or ContextCapture offer this feature, our use case would be to avoids cloud or meshes flaws due to the reflections using hundreds of already digitized polygons (and their elevation data).

Feature Requests / Import of gltf/glb v1/2
« on: July 26, 2019, 12:25:49 PM »
Metashape offers the export function of this format, its use in other softwares is increasing and it would be great to be able to import it too.

Texture De-Lighter / Agisoft Deligther Documentation
« on: June 11, 2019, 11:12:07 AM »

There is a new standalone application, Delighter, which seems to have a larger set of function than its Remove Lighting  Metashape's counterpart. When I click on the "help" menu I get nothing back, is there some documentation or tutorial planned ?

Bug Reports / Aligning - no remaining time shown
« on: August 21, 2018, 09:52:42 AM »

I've launched an alignment on 47.000 cameras, the process is now at 99% but no remaining time is shown. The file log wasn't activated but I've joined the last 10000 lines shown in the console, can you tell me if this process is going to fail ?


General / How to process a dataset with millions of photos ?
« on: August 06, 2018, 03:33:56 PM »
Hi everyone,

I would like to know if anybody here has implemented a process able to deal with millions of photos with Photoscan, if you have any feedback I am listening !

One of the dataset we are building contains +7 millions files and will double in the next months, all these pictures were taken with the same camera model and are georeferenced. The resolution is low (2008x1680, 3.37Mpx) but enough for our use cases.

While I am used to deal with massive lidar or raster datasets, I have not figured out how to achieve it with Agisoft Photoscan. Even if it is divided in 1400 alignment subsets which will themselves be subdivided with the script, I don't know how to get to a seamless textured mesh without many manual interventions.

The chaintool I'm thinking of so far :
1. align 1400 subsets
2. divide them in chunk with an overlap for densification
3. export the point clouds and merge them back with PDAL
4. sample the cloud to get an homogeneous density (remove the overlap effect)
5. tile and mesh the output
6. bring ten of thousands of chunks back in PS for texturing

Problems :
1. python or manual work is required for loading cameras given a file list, is there a size limit for a project ?
2. python or manual work as it is not available as a batch process
6. python or manual work for loading the tiles and the referenced cameras, size limit of a project

And surely some others I can't think of right now :)


Feature Requests / Add overlap/buffer handling to core processing
« on: July 23, 2018, 10:46:37 AM »

I would like to suggest extending the overlap mechanism integrated in and integrating it into the core of Photoscan.

This feature is critical to get perfectly joined chunks without artifacts but it only works one way at the time of the creation of the chunk by the script, there is no way* to reduce the chunk to its original size before merging it back with the others ( * without using python).

LIDAR chaintools like LASTools or PDAL include the concept of buffers when tiling a dataset, it allows to work on each chunk with overlapping data and discard the flagged buffer when needed.

I think there should be three functions :
- add overlap (both a parameter and a processing stage)
- use overlap
- discard overlap

These functions would make it easier to have a full photoscan workflow without painfully exporting/importing on large projects.


Bug Reports / Activation fails with 1.3.0
« on: February 17, 2017, 01:14:09 PM »

Here are the steps I followed to activate my version of Photoscan Professionnal
  • v1.3.0 has been installed in a repository where I have write access
  • As the activation requires admin privileges, my IT dept. wrote in the serial number and the activation.act
  • I've send this file to support@agisoft and got a *.lic file back
  • This file is set in the software's root folder

Photoscan doesn't seem to take it in account and is now showing xx days left in the windows's bar.
