Feature Requests / Calculate volume from min height from shape

« on: March 09, 2023, 12:19:33 AM »

Hi,

we had a project where customer has given us a shape file with exact heights/depths of foundations that needed digging. It was a curved road going down a slope. I was surprised to find out Metashape cannot calculate volume above such shape but only uses fitted plane for calculations.

Would it be possible to calculate volume not from a fitted plane but from surface constructed by shape with Z values?

Feature Requests / Re: thermal images multi camera system process

« on: November 29, 2022, 05:28:22 PM »

Dear friends,

• export the 2nd plane of thermal Rjpeg as 16 bit single band tif imagery;

For this process, a script could be developed, resulting in something similar to following screen...

Hey, I'm still fighting with this and since Agisoft gave me 0 replies to my ticket, I would need to develop script as you described. I have no problem writing in python/perl, but I'm looking for library/toolkit for working with RJPEG. Do you have any recommendation for that?

Thank you[/list]

General / Re: combining infrared and rgb camera

« on: May 18, 2022, 06:04:29 PM »

Hi, unfortunately this approach is not working with Duet-T camera from Sensefly.

Hello 2bForgotten,

When you have separate synchronized sensors it is suggested to use Multi-camera system approach. In you case:
1. Create a new directory and then two subdirictories in it. Call them "1-RGB" and "2-IR", then put the images to each folder coming from the certain sensor - the order of the images in the folder should correspond to each other.
2. In Metashape interface use Workflow Menu -> Add Folder option and point to the "master" directory created in the beginning of the previous step. In the Add Photos dialog shown shortly after the folder contents are analyzed, select Multi-Camera System approach - > "Create sensor from each subfolder" option.
3. After loading images go to Tools Menu -> Camera Calibration dialog and, if necessary, enable "Reference" option for the slave sensor. In case the offset between the sensors cannot be neglected, then enable also "Adjust location" option. Additionally make sure that Layer Index in the Bands tab is different for Master and Slave sensor.
Approach would work if the sensors are synchronized and their relative exterior orientation doesn't change during the capturing process.

Hi,

in my case using a sensefly Duet-t what works for me is to leave the rgb images in the folder and create a subfolder inside with the thermals.This way agisotf understands that the one outside are the masters and the subfolder the slaves.

On the other hand, could you please share the script to convert the images to .tif with temperature values?

Best regards

For me it do not recognize Sensefly duet-t as multicamera this way. What is your exact naming for folders?

General / Re: Quality improvement of orthophotos in areas with high vegetation

« on: April 13, 2022, 04:30:47 PM »

one more things to try is play around with DEM you generate, perhaps maybe try to generate DEM from dense cloud without vegetation sometimes resulting ortho of vegetation is better that way

Bug Reports / Re: Depth filtering always stuck on Mild

« on: April 11, 2022, 06:59:18 PM »

Hello MichalDV,

At which point the depth maps generation is stuck (any fixed % value)? Can you provide the processing log from the task start up to the stuck state?

Hi Alexey, "stuck" was unfortunate choice of words, it will finish, but no matter what setting of depth filtering I choose (lets say I've selected Aggressive), it will always use "Mild".

I've just sent logs to support.

Bug Reports / Depth filtering always stuck on Mild

« on: April 11, 2022, 04:43:27 PM »

Hi,

I'm on version 1.8.1.13915 on Windows

No matter what I set in Create tiled model menu, it always generate Depth Maps with depth filtering on Mild. I wanted to try another level to fix some artefacts..

Screenshots in attachment.

EDIT:

1.8.2.14127 has the same issue

General / [SOLVED] creating large mesh stuck at BuildModel.facesMerge / decimating seams

« on: January 14, 2022, 10:54:36 PM »

Hi, I'm processing rather large mesh, and during processing, at last 99.5 % overall progress it got kinda stuck at BuildModel.facesMerge / decimating seams.
First it consumed a lot of RAM and Pagefile, but since I have like 5 TB of pagefile it did not run out. Suddenly after few hours it emptied all allocated RAM, and now it is doing nothing, so 0 ram, 0 CPU, no disk activity. Should I wait or what to do?
It has happened twice in row and it is last bit of processing before it is done.

Last item in log is:
decimating seams...
25049214/2325036307~1% seams vertices, 86601676/2325036307~4% vertices near seams

General / Re: reconstruction has wrong orientation after alignment

« on: November 29, 2021, 11:10:28 PM »

So I was looking more into this issue, and it seem that position information should be pretty good since it was RTK fixe

Drone is MAVIC2-ENTERPRISE-ADVANCED

XMP data:

Code: [Select]

Rtk Flag                        : 50
Rtk Std Lon                     : 0.04870
Rtk Std Lat                     : 0.06500
Rtk Std Hgt                     : 0.10221

General / reconstruction has wrong orientation after alignment

« on: November 26, 2021, 06:40:30 PM »

Hi,

I have one dataset from customer, where after alignment it is tilted ~20 degrees to one side. Would you point me in direction how can I fix that?

I've tried discarding orientation info from Reference, and also increasing accuracy (m) for geolocation data.

Hello MichalDV,

Thank you for the update on the issue, will try to reproduce both problems.

Hi Alexey,

did you have any success reproducing our issues?
