Feature Requests / Agisoft Viewer -- Slice View / Section Plane / Limit Box

« on: June 23, 2023, 03:19:24 PM »

Hello

I Made a post a few days ago here https://www.agisoft.com/forum/index.php?topic=15615.msg67709#msg67709
About the Difficult of navigating building internal in Agisoft Viewer

Our Clients seem to really like the Viewer, and we would like to give them more on it. Currently, we only give them building externals and aerial topo, but we would have the data for internals also just for making building plans or bim models. can can make the model with internal but there is no point if who can see it of measure stuff in the rooms

So my request is for so Method for seeing inside models like a Slice View or Section Planes or a Limit Box

It might be handy to have in metashape also
Thanks

General / Agisoft Viewer, Navigate building internal

« on: June 17, 2023, 02:49:34 PM »

Hello

I created a tiled model from Laserscans only. it was scanned with a blk 360 and I noticed oddly extra triangulation off the limit of the scan data, kind of an umbrella effect. Its not so important really but odd so I tried masking the scans empty and run it again, which didn't help

I link https://mega.nz/folder/ZGwxQYAJ#Xf2uRKwS1beWW_I4g0tfyQ here the 2 scan for anyone curious

Anyway I am really asking if there is a good way to navigate the inside of a building in the viewer, or something like a limit box or section planes for viewing the floors?

Also for whatever reason textured tiled model that get their texture for the greyscale intensity of laser-scan data, disappear when I zoom in. this happens in metashape and the viewer? i have to view them in solid

General / Mavic 3E and Trimble X7 Alignment

« on: May 23, 2023, 02:07:15 PM »

Hello

I'm having huge issues with this workflow, https://agisoft.freshdesk.com/support/solutions/articles/31000168474, 

I have followed the Tutorials and every conceivable combination, but either my scan data which is georeferenced in Trimble Realwork, get moved in crazy location with my drones sparse cloud (laser scan group rest alignment[N/A]), or does not find any matches with the point cloud in the fixed position [R]

Does the E57 you using need to be a coloured point cloud to work?
I tried PTX and PTS with no improvement

My Pointcloud are greyscale intensity and I am only getting 22 match, at most between the scan data and the photos
also, some of the matches are very wrong

When I Import Laser scans there position/rotation (From Origin on import) is in the estimated area? I tried "From Unknown" on import also.

I tried Importing them in the Coordinate system of the photos and local coordinates

I tried all the above multiple times in 2.0.15, 2.0.16 and 2.0.2 with no improvement

I also tried using the layout script but this didn't seem to have any effect.


Attached Picture 1 shows the Low match count,
Attached Picture 2 shows Bad matches and also Valid matches which I would say are incorrect
Attached Picture 3 shows LASER SCAN GROUP being rotated out of position


There seem to be a lot of people here with Mavic 3E, maybe would use laser scan data also, could I DM someone for help

Can't open file; the device does not recognize the command (22)

While Building Planar Orthomosaic for front elevation of a building.

Disabling the laser scans allowed the creation to complete

General / Mavik 3E Aerial + Trimble X7 Leads to "assertion" error

« on: February 07, 2023, 05:34:43 PM »

Hello All

We do Aerial Surveys and Building Scanning. We have also wanted to try and use the two datasets to create Models for clients but never had any success with the earlier versions, but this week upgraded to 2.0 which looks like it has a simpler workflow

I Imported some Mavik 3E Aerial photos and a few E57 Laser scans around the Elevation of our Building. Follow the few steps and Align the Photos, Put the scan in the group and set them to fixed as they are already georeferenced, and I get 2 different errors. If I generate a dense cloud from the photos and try making the Mesh from a limited area, by classifying an area of interest as building and trying to make a mesh from the point cloud, I get an Image out of Bounds error instantly, If I try and make the mesh out of the depth map and laser scans, it runs maybe halfway and gives the error "assertion failed at line 1123". If I remove the Laser scans from the project it works as expected.
So my Laser scans are causing the problem or Metashape cant handle my scans

The laser scan is captured with a Trimble X7 and georeferenced in Trimble Realworks and Exported as E57
Does anyone see a flaw in my workflow??
Does it matter that our scans are only intensity shaded with no colour or picture?

Can any who has and X7 and Drone tell me how they do it?

Thanks in advance

Bug Reports / metashape vs photoscan coordinates systems

« on: May 27, 2019, 12:26:22 PM »

hello all

previously when transforming fro WSG84 to Irenet95 ITM the results where exactly correct compared to the official transformation tool provided by OSI

Since the update to meta-shape 1.5.2 there is an error in the easting northing after translating

I originally thought is was an error with the addition of the custom datum, malin head, but this has been resolved and is not the cause, that link is here
https://www.agisoft.com/forum/index.php?topic=10701.0

I may be related to the issue here, possibly

General / How to tranform to Irish Transverse Mercator, with Malin Head Datum

« on: April 03, 2019, 11:19:16 AM »

We have tried and tried, downloaded the geoid, making .prj files, and we still have no solution

We have drones that geotag photos using rtk, accuracy less than 20mm, an we would like to transform the coordinates into the correct Irish Transverse Mercator, with Malin Head Datum, before aligning them

Even after the downloading of the goeid model osgb36_osgm15.tif there is no improvement, still the tranformed coordinates are off by maybe 50 meter in height

Can some help us please??

General / Filter Images by Markers not working

« on: December 21, 2018, 07:30:45 PM »

Using version 1.4.4.6848

Filter by marker does not work, I have tried all this http://www.agisoft.com/forum/index.php?topic=9569.0
Filter image by anything(point )

Pinning three of the markers by hand in 3 images each
and making a low poly mesh from sparse pointcloud

project contains 1480 images flown with Sensefly camera, image have gps data, image errors in excess of one meter using gps data, gps data was rtk linked for accuracy
, flow in high wind, missing or blurry images excluded from project


Sometimes when pinnigng gcps, coordnate system for markers woulf rest to wsg84, marker collected in itm(EPSG Code: 2157)

Any Ideas?
