General / How does alignement parameters affect the final result ?

« on: June 07, 2021, 04:09:37 PM »

Hi,

i'm not sure i understood well how much the alignement parametters affect the final result (mesh quality).

Is there a big difference between low and high alignement ?

Is the number of points important ? Will i get a better result if i set max keypoints to 1 000 000 / 100 000 instead of 40 000 / 4 000 ? (with 60mp photos)

I have the impression that sometime "highest" setting give me worse results with a lot of noise.

General / best way to merge two different quality meshes ?

« on: February 18, 2021, 06:43:29 PM »

Hi,

i'm working on a cathedral door project.

The aera of the door is very well defined and deserves a very high quality mesh.
The surrounding is not as well defined and i want to use only mediu quality mesh, i won't have many details but it will show how it looks.

is there an easy way to merge the high quality centered mesh with it's medium quality surrounding ? and what would be the best way ?

General / Questions about network processing

« on: February 18, 2021, 02:00:54 PM »

Hi,

i'm starting to think that the best option to get projects done a lot quicker is to use the network processing feature.

where can i find documentation on how it's working ?

I was wondering if it's difficult to use ?

If i buy some computers that will only be used for this:
* how big their hard drive (ssd) need to be ?
* is a very fast ssd important ?
* how much memory do they need ?
* will they benefit from a 10 gigabit lan ? (requires a specific lan card)
* is whole processing power multiplied by the number of computer ?
* will a 4 computers setup will be twice as fast as a 2 computers one ? 4 times faster than a single one ?

General / Need advice for pc configuration

« on: February 15, 2021, 06:55:05 PM »

Hi,

i have two pc working on metashape projects (a 9900k/128Go/3080 and a 5950x/128go/3090). those are great but VERY expensive.

i'm thinking in buying 3 or 4 more computers to be able to work on more projects at the same time, but won't be able to buy such expensive configurations.

What cpu/memory/graphic card combination would you advice to get something efficient with metashape for a decent price ? (won't be used for anything else, just metashape)

Hi,

one of my client is using assimp.org to import models.

when trying to import a big obj model (50M faces) exported with texture from metashape, his system is throwing this error : "Validation failed: Mesh contains no faces"

I had the same issue with 3 models.

do you know where it could come from and how i could fix this ?

Hi,

i currently have a 9900k / 3080gtx / 128go ram computer.

without budget limitation what would be the best upgrade ?

would a workstation with multi cpu or a Threadripper PRO be a lot faster ?

(using windows 10 pro)

« on: December 01, 2020, 07:14:15 PM »

I find it very difficult to rotate the model with the mouse when the "rotate sphere" is not visible.

General / how to set vertical orientation manually ?

« on: December 01, 2020, 07:12:20 PM »

Is there a way to tell metashape what is the correct vertical orientation ?

When i stiched 2D panoramas, i can choose two points verticaly aligned and the it will be used to set the correct orientation.

Is there a way to make this in metashape ?

Each time i rotate the model to see another angle i struggle to put it back vertical. I would like to be able to click on a button and have the model vertical back. Is it possible ?

General / How to tell metashape where the photo was taken from ?

« on: December 01, 2020, 07:03:04 PM »

Hi,

i'm taking 360° pictures sets to use in a photogrammetry project.

i know where the station is and where the camera is facing (pitch, yaw) for each of the photos (i'm using a motorized head i have developped).

How can i import this information into metashape when adding the photos ?

General / Use stiched 360 picture or individual pictures from station ?

« on: December 01, 2020, 06:51:21 PM »

Hi,

i'm starting a photogrammetry project. I'm taking many 360 pictures sets ( more than 20 sets) in the Sainte Chapelle in Paris (one exemple: https://kuula.co/post/7CKPMs).

This is my first try with photogrammetry using 360 pictures sets.

I was wondering if i should stich each set in a 360 equirectangular picture first or import all photos in metashape and use the set as station feature for each group ?

Each group is made of a little more than 300 60MP pics (from 7r4 with a 70mm lens).

What is the max picture size to import into metashape ? each stiched 360 picture is between 8 and 9 gigapixels.

Thanks
