Bug Reports / zero tie points
« on: October 22, 2021, 01:04:58 AM »
Recently my colleague Simon Brown has had this weird issue. Right after aligning successfully a set of photos, there is no region and no tie points. How is this possible?
Repeating alignment has worked again as usual.
I'm lost.

Hello Alexey: Have your fixed known issues with cylindrical dem>ortho?

Best regards,

Feature Requests / quantities to attributes
« on: May 04, 2021, 08:15:17 PM »
It would be a good idea an option to write the result of volume measurements to the attributes of the shapes used for their estimation.
Along with quantities the list of attributes should include method and parameters used for fill/cut calculation and perhaps timestamp so quantities can be linked to a given DEM status or creation date?

Best regards.

General / Intelligent paint... is it of any use for you?
« on: September 19, 2020, 01:06:43 PM »
I've been using Photoscan and Metashape for ages, but I still cant figure out how this tool has been with us for so long. Sorry but I can't make it workable at all. Can anyone post a good example of its use that can justify why we do have such a long-standing tool, but we can't have instead a simple but effective user-sizeable circular brush.
Why this intelligent paint does not even reset when one hits esc to try again? what am I completely missing?

Thanks

Feature Requests / Invert tilt movement in terrain mouse mode
« on: September 07, 2020, 09:38:16 PM »
I have requested it some time ago and complained about the weird mouse behavior in Terrain mode.
You argued that in the current way it was more consistent with other applications in the market... I then wondered which ones.
At the end I never use this mode because it hurts my brain so much.
But now that Agisoft Cloud uses the mouse movement in the right way. Therefore I beg you to be consequent and change it in Metashape Professiona to work as it does in Cloud. If not, at least please, add a tweak for letting users to invert terrain tilt direction to match Agisoft Cloud.
Best regards, and congrats for the nice website design.

Feature Requests / Spherical targets
« on: August 03, 2020, 08:59:30 PM »
Hello, Agisoft:
Spherical targets are widely used in terrestrial laser scanning. They are convenient due to de fact that a sphere looks the same from any pont of view and does not require being orented towards the sensor like planar targets do.
I guess it would be really usefull if Metashape where able to detect a sphere centre point automatically as it does with circular targets. It would help laser scanning works to be co-registered with photo scans.
Unlike planar circles, spheres always look round enough in a picture regardless the angle of view, so a circular feature detector, should work fine, even when it is not surounded by a black crown like in non coded circular targets.
Please keep improving Metashape by adding funtions for a better integration with TLS.
Best regards

Bug Reports / Drag view changes model orientation
« on: October 22, 2018, 01:09:50 AM »
Yes, this sounds imposible, but if you have a scaled model that has been rotated manually so scene XYZ axis are coherent with object principal directions, if you drag the view, your axis will rotate about Z. This unexpected behaviour has driven me crazy for quite a while... and is totally nonsense from my point of view.

As well, it is annoying that if one rotates object, then sets a scale bar and updates... Photoscan will on its own modify model rotations instaid of just scale it

Why without my permission? WHY?

EDIT: This odd behaviour can be reproduced, however it seems not to be a general case. In my particular case, I'm processing photos that had geotags. I cleared them before alignment, but still the coordinate system remains as wgs84. I have noticed that resetting transform and changing to "local coordinates" makes things work as they should.

Feature Requests / filter photos by doble click
« on: October 03, 2018, 03:21:12 PM »
It would be nice to speed-up the "filter photos by marker" by doble click on a marker in the list.
1. if done on the project tree
2. if doble click is done in the ref pane, currently one enters rename mode for marker name. In my experience renaming a marker operation is done more rarely than the filtering by marker, so I would prioritize the filter by... and put rename as a context menu option only

Alternatively, you could make the flag symbols of each gcp in the ref pane list (currently they are just esthetic), behave as a "filter by..." button by single click.

Kind regards

Bug Reports / Issue with OPK angles
« on: September 25, 2018, 08:01:04 PM »
Hello friends. I've found what seems to me a bit of a bug:
Have a project with photos having lat, lon, alt, yaw, pitch, roll, already aligned.
Now have a GCP text file with names,X,Y,Z
When you import this file with OPK as rotation format option selected in the dialog, even with rotations import check disabled, it will force change project to OPK mode causing problems with the camera rotations.
In my opinion this dropdown option in the import dialog should be disabled unless the rotation import is checked.

Regards,

General / Using Dji Gimbal angles.
« on: June 19, 2018, 04:49:15 PM »
This an old issue but not fully understood by me.
the topic http://www.agisoft.com/forum/index.php?topic=7286.msg35063#msg35063 included some useful code to list gimbal angles and aircraft angles as well. By using it, one can notice that none of them correspond to what one could wish (something close to the estimated angles after a successful alignment with ground control)

Extracting angles from XMP data by means of the built-in funciton will lead user to wrong input data because it imports the so called flight angles rather than the gimbal ones... so it is useless. But even if it had read the right metadata, one would find that when camera is looking nadir, the gimbal pitch is stored as -90.0 while if used agisoft's convention it should be something close to 0 degrees. So it is likely DJI uses NED (north-east-down, typical for aerial vehicles) rather than ENU (east-north-up) convention.

Alexey: could you please modify the "read xmp" function so that when reading camera angles from dji, it can pick the right entries and convert them to the same convention used in photoscan?, if you do not consider this modification to be a good idea at all, could you please modify the py code in the related post so it can work as desired and filled photo angles to the ref pane?
Thank you!

Feature Requests / Agisoft Viewer dedicated installer.

Agisoft view installer.
I'd like that agisoft Viewer had a dedicated installer, even a portable build. Is there anybody wanting the same?

Bug Reports / orthomosaic edition odd behaviour
« on: April 18, 2017, 02:30:46 AM »
I have a buiding model and created orthomosaic for façade A, did some edition by assigning different images to pollygons with no problem, then exported the ortho.
Now moved to façade B, still the same chunk referenced just the new ortho is created from a new point of view. And now I cannot create shapes on the ortho?. To be more exact, I can start drawing a shape but when closed it disappears at the last clic.
this bug had been reported happening in previous version too so please, do something asap!
best regards

Bug Reports / Trackball
« on: March 07, 2017, 08:17:46 PM »
Hello, Alexey:
Set trackball item to hidden
choose rotate object tool and the object trackball is shown but user is not allowed to use constrained rotations. This behaviour is not very consistent in my opinion. If the rotate object tools overrides scene trackball visibility setting (nothing to complain here) then it should work as usual when user picks its main circles.
I wish one day the GUI will offer better feedback of the active tool by means of differentiated cursors.

Bug Reports / Wrong roll estimation in 1.3
« on: February 06, 2017, 10:25:11 PM »
Hi, Alexey:
There must be a bug in the roll estimation because in a project composed of 790photos hand held, 545 show 0.000 as estimated roll value... others show values close to -180 or to 180 but they alternate with no reason. Apparently all photos have been well oriented and pixel errors look fine.
I also have noticed that automated marker propagation stops functioning without reason after having merged two chunks.
Look carefully attached images and tell if selected images explain the shown roll estimated values in each case.
Yaw doe not seem consitent either. the last example with three images that were taken sensibly perpendicular to the façade, appear to have very diferent yaw angles.
Best regards!
