General / Ruler inactive for referenced PointCloud [R]

« on: February 24, 2023, 09:04:22 PM »

Hi,
I have an imported point cloud. It is properly scaled and referenced. Metashape assins [R]. But still I cannot use Ruler. But I need it. Adding some scale bars do not help, not enought reference data. What can I do? I can draw points and export them into txt. Or see coordinates by adding markers. But it is too slow, I need the ruler tool. Thanks.

Bug Reports / Animation axis error

« on: January 27, 2023, 10:00:47 PM »

Hi,

horizontal and vertical options in creating animation seem wrong. Axis are set wrong and therefore animation is not usable without a lot of manual work. Please fix, Metashape Pro 2.0.0. See attachment. Thanks.

General / Show shape labels

« on: November 22, 2022, 10:48:23 AM »

Hi,

after drawing points... I think there use to be possible to show shape labels on a 3d model. Now in 2.0 version "Show shape labels option" does nothing on a point cloud or 3D model.

It works when the shape layer is selected but only white background is visible - no 3D model. Another error or intention?

Thanks,
Filip

General / Planar orthomosaic error

« on: August 19, 2022, 07:08:52 PM »

Hi,

I have developed a workflow but with metashape software update, it is now not fully functional. When I generate planar orthomosaic by markers and I have previously clicked "Remove projection" on markers, there is an error. It was not in previous versions.

I need to correct manually coordinates of the markers and so I do not want them to be projected on the model. Why do you know insist on it?

Thanks, Filip

General / Aligning 2 laser scans manually

« on: March 18, 2022, 10:49:45 AM »

Hi,

somehow two of my laser scans did not align (with other laserscans and external 360° camera photos). Still I would like to align them manually. But I am not able to use manual marker matching because the photo of laser scans is displayed in metashape with very bad quaility. The picture should have 4096x2048 but it is not what I see and what I can work with. How can I display it better?


Thanks, Filip

Feature Requests / Improving Measuring tool

« on: March 01, 2022, 01:23:19 PM »

Hi,

I am quite used to (from other software) functions concering the measuring tool which are missing in Metashape. I would like to measure not only direct slope distance between two points, but also distances in horizontal and vertical planes between the same two points. It is a very handy function.

E.g. a windows has some artefact below and above but still you can find points which are fine. But they are not above each other. You want to click somewhere below and somewere above the window (points not vertically one above the other) but you still can get a correct height of the window.

It does not seem support is frequently solving threads and user's impulses here in this section of the forum but still I am trying here rather than in General section.

Thanks, Filip

Bug Reports / Unsupported datum transformation - CESIUM ION

« on: February 28, 2022, 11:02:24 AM »

Hi,

I am trying to upload an tiled model from Agisoft Metashape to Cesium ION. The error is “Unsupported datum transformation.” The project is in local coordinates coresponding to Czech national systems - but in Metashape it is just an ordinary cartesian system, nothing special.

When I try to upload the tiled model in WGS-84, there is another error:
Response code: 404
Response data: {"code":"ResourceNotFound","message":"/v1/assets"}

Any idea if the error is related more to Cesium or Metashape and how to solve it? Thanks.

Bug Reports / Tiled model solid

« on: February 18, 2022, 09:45:23 AM »

Hi,

when switching view from Tiled model textured to Tiled model solid in Metashape 1.8.1 Pro, the software crashes. All the times. It was fine in some previous version. Bug report sent to Agisoft throught automatic dialog after sotware crashes. I would be glad if you check this issue. Quite important. Thanks.

General / Registering laser scans

« on: February 05, 2022, 11:43:03 AM »

Hi,

I am not an expert, rather starting experimenting with combining photogrammetry (aerial+terrestrial) with terrestrial laser scan (TLS) data. I am a surveyor and I need a centimeter accuracy of point clouds of buildings. Is Metashape fully usable for this purpose? I see in other threads that many people have doubts about it. My question is how accurate is scan registration from structured ptx or e57 formats. Only

I have access to data from Faro Focus M 70. Maybe an older model, I am not sure about camera parameters. But it takes too long to capture colored 360° panoramas from the scanner. Therefore we have only infrared panoramas which are much quicker to take. But additionaly we are using 360° panoramas (from photos or videos) from an external 360° camera (outside scanner). We are using this for scan registration outside of Metashape.

But I would like to try to do as much as possible only in Metashape. External 360° panoramas from inside of the building are not good to be used in generating points in final point clouds (along with TLS data). They should be used only for registering scans. I do not know if this is possible. If I do not add that 360° photos, TLS data are registered anyway (from IR panoramas) but only with very little number of tie points. But I have doubts about how accurate that can be.

General / Georeferenced planar orthomosaic (fasade)

« on: January 25, 2022, 04:59:01 PM »

Hi,

I can achieve somehow what I want but only in a too complicated way. My goal is a georeferenced orthomosaic of a fasade of a building. I have read an Agisoft tutorial https://agisoft.freshdesk.com/support/solutions/articles/31000154049-orthomosaic-generation-planar-projection-. But not much usefull concerning this issue. Also note that there do not have to be orthogonal fasade structures enabling for such a process.

I want an orthophoto of a fasade based on georeferenced model coordinates. Now I obtain relative coordinates which needs a quite lot of steps and time to get it back - where Z coordinate is right again.

I use "Markers" projekction plane (Planar projection). I define 3 markers on the fasade (e.g. on the tiled model). Afterwards I remove those projection on the model and edit height (Z) of the two horizontal points to be the same. In order to have georeferenced model, I tried to mark my 3 markers on some photos (without changing there positions). Now I am getting hopefully right output with  good rotation and relative coordinates but not absolute. Center point of my local coordinate system (defined by my 3 markers) is set to 0 on the final orthophoto. It is the same even if I do not remove projections of my 3 markers on the model. Not sure why. And I have to move the picture in the CAD program to the absolute position in Z coordinate to match the whole model.

I think there should much simpler way. Is there any already and am I missing something? I just want a georeferenced orthomosaic which shloud be quite a very common requested output. Why not to give to the point [0,0] of a mosaic a real coordinates from a georefereced model? Many steps I have to do now are not necessessary and even sources of errors.

Thanks
Filip
