General / camera path change doesnt work with many images
« on: July 11, 2019, 02:35:48 PM »
Hi,
I see having received back from Agisoft the images of the brake shoe, when I double click an image i get  path not found, The project has had the images placed into a folder 'brake shoe' on your PC so my address is different.

I select the images that were chunk 1, that came from a folder called face 1, ignoring those that came from chunk 2 and right click>changePath>selected cameras but that folder has nothing I can select, its saying select file, its full of jpgs but I cant see any.

I am unable to tell agisoft metashape to source them from that folder.

If it said select foldet that would work, but saying select file and showing me nothing yet they are there !

I try again selecting one image, this time I see that image, select it and now metashape will open it.
As I have many images I cant do that for each one. :(

If I choose all cameras then thats wrong as some of my images come from folder face2.

I try again selecting 2 images, and it shows one of those, I select that, and both are now launchable.

somewhere in this it falls over between 2 selected and many.

General / Re: Agisoft filling in bolt and rivet holes I need to see.

Hi Alexei,
Low for speed, that answers that one I guess as I wondered why you used LOW when I was after speed and quality better than Photoscan.
I will amend METHOD D steps accordingly.
Also I will add:-
- remove (reset) all the masks from the chunk,
- mask the six holes in the objects on the very first image from the set (that is looking from the top on the object),
- run Build Mesh (in Metashape 1.5, of course) using Depth Maps as a source, same quality as the existing depth maps in the project (enabling Reuse Depth option) and using Strict Volumetric masks.


to METHOD D.

AM I RIGHT IN SAYING THIS FITS IN 'AFTER' THE BUILD DENSE CLOUD STAGE ?
as it just mentions build mesh.

to my mind one needs to modify the mesh then let it influence the Build Cloud stage as well as mesh stage ?

Hope we can soon put method D up as a step by step for users who move objects and move cameras around the objects.

Hi,
forums normally have means of sending a member a PM, and sometimes they get a notification of that fact of being sent a PM in their email, I cant see any means of creating a PM here..

General / catch 22 need masks to align photos but initial align fails
« on: July 11, 2019, 12:02:33 AM »
Hi.
metashape 1.5.3

fundamental catch 22.

1) align photos, 3 chunks because object 3 positions relative to background, get an overall 43% failure rate.
2) it was then to be dense point cloud then mesh then edit background out then mask from model then merge chunks then realign photos,

will all that work so as to get mask from model with almost half failed ? model wont be  good., mask wont be good.

catch 22 you  need mask from model to then re-align well yet unable to get initial photos to align without masks !

I see that David Cockey uses this method, any help David or anyone appreciated.

update ....went ahead and edited out background, import mask from model, 21 masks appear from 54 photos, of those they are all chunk 1, chunks 2 (18 pics) and 3 (8pics) none.

Hi,
Accessing tools by having to slow down and click on a little black triangle then select from a tiny icon when switching between region modifying tools and also object modifying tools makes for very slow working, all that empty grey bar to place them in as well making the picky tedious drop down lists unecessary. .  Can we have an option to distribute them along the bar instead for faster working or just in a version update lay them out there anyway, no one will mind I would think seeing the tools all to hand and being faster to access anyway. Also maybe different colour for the object tools than for the region tools as they can be a bit similar.

Steve

aha, so depth maps not a new innovation in metashape then. also interesting that using high when building dense point cloud sees the option to reuse depth maps greyed out in mesh stage, . we must use a lower setting.

Hi,
would do but that sees exif data with contact details and so on included which I dont put out on internet.
I could strip it out but then I have to add it all back in again else pshop wont save it as such.

General / Re: localised decimation option would be FANTASTIC ?
« on: July 07, 2019, 12:11:09 AM »

The decimation tool is already adaptive and is trying to maintain higher number of polygons to the details compared to the plain surfaces that would be reduced to the low number of polygons.
see attached. not v good.
will have to use meshlab or similar to try and reduce mesh yet preserve detail areas.
Quote
But I've got your idea regarding the decimation of the selected area only.
  good, hope to see it soon  :)

As a workaround I could suggest to smooth the certain selected areas with high number of steps (strength parameter) and then decimate the model.
Where do I find that procedure ? aha smooth mesh dialog box, check box to apply to selected faces, I will explore.

Cheers,

Hi,
Where is the option in Metashape and also photoscan 1.4.5 to lay out tools side by side for working like I am so used to in photoscan 1.2.6 ?
since using Metashape and Photoscan 1.4.5 I am finding my speed of navigating and working seriously impeded by having to carefully select a little black arrow each time I want a different tool, I go scale rotate move scale region then rotate object move object and so on very quickly and now I cannot, how do we get the separate tools to be separate again, there is all this vast empty grey bar for them to all be easily picked from as they were in 1.2.6 and they are now in drop down lists requiring fiddly selection of a black arrow then selecting the tool, its double the selection time with slowing down on hitting the black arrow ,and its taking ages, I could work so fast but not now. Its as if someone thought isn't that slick to have them in little drop downs but its impractical ! Messing about waiting for processes takes up our life but please can we gain time and have the easy access tools back.

I have looked in preferences for an option to distribute them on toolbar but found nothing.

I dont want to revert to photoscan just for the decent tool layout.

General / Agisoft filling in bolt and rivet holes I need to see.
« on: July 06, 2019, 10:25:17 PM »
Hi,
I have holes as part of the engineering item yet they are being filled in by Agisoft it seems as I have top quality photos.
Brake shoe Alexei !
I am sure I saw an option somewhere for fill holes, I dont need it, I need to see bolt holes and rivet holes.

I am now looking at the workflow steps in metashape as I have managed to get the file recreated as per your fix you carried out in metashape. Thank you.

I can't see any hole options anywhere.

I need to resolve this else every project will be useless if these holes get filled in.

Hi,

Only way to re-use the available depth maps is to select the same quality option and check on "reuse depth" option (in Build Mesh or Build Dense Cloud dialog).

I have GPU GTX970 cuda ticked and CPU tcked in preferences which according to the pdf manual is correct if using single GPU.
PC is 32Gb ddr vengeance pro Intel Core i7 4790 3.6GHz  win 7 64bit pro.

Following the need to keep my Ultra high quality , as a test to see what happens with ultra high in mesh after ultra high in Dense point cloud,
2hr 20 mins of 'accumulating dense cloud' then phase 2, and after 45mins of it saying building model 0% it said 48 days remaining, I dont think 48 days is good for anyone, not on a single small wheel and axle. clearly something got stuck at the building model phase.

I hit cancel as clearly there was something wrong with choosing ultra high mesh after ultra high dpc. (in photoscane 1.4.5) or was it ticking and using strict volumetric that caused the problem ?

Trouble is whilst PC is spending hrs processing as such I cant use it on anything else as one cannot minimise agisoft, also its using all resources so everything else sees a jerk y mouse, CAD and photoshop would be impossible.

I will try again, this time with Metashape where , as you say, retaining ultra high depth map needs ultra high mesh setting, to see if Metashape also has the same issue.

Hi,
1 and 2...yes understand that as , if depth map uses arbitray 3D then thats why its denied as a choice, its greyed out.
when you had said
Quote
2) Build Mesh (only if both Arbitrary surface type and Depth Maps source options are selected),
it was  the fact that one cannot select depth map AND arbitrary3D. it should be depth map (arbitray greyed out)  OR densepoint&arbitrary 3D.

Quote
"Quality" parameter in Build Dense Cloud and in Build Mesh (when Depth Maps source is selected) has SAME meaning - it is the quality of the depth maps

As such, I need to know though , if Depth map is made with UltraHigh densePointCloud, so we have UltraHigh quality depth maps, does choosing High in mesh mode reduce the depth maps from ultra high to high lessening their quality ?

should we also then use ultra high in mesh mode to retain the quality of the ultrahigh depth maps created in densePointCloud stage ?

I am running ultra high mesh on ultrahigh densepointcloud in photoscan and big problems with time its taking ,see posted thread.

Hi,
Photoscan 1.4.5
small trolley wheel and axle.
I have created dense point cloud using ultra high aggressive, took 6.5hrs
now to run Mesh ultrahigh to see if I can get better detail than with mesh high, use strict volumetric masks.
started it at 21:51  accumulating dense cloud until 00:11, thats 2hr 20mins on that phase of the operation, but now...
now building model it says and after 45mins still 0% done

and now its saying 48 days left !!!!!

aborted it .
saved it  2.4Gb strewth !!!

WHAT IS WRONG ????

Hi,

Further to awaiting advice on decimation, which basically messes up a formerly good mesh for CAD use, all the detail I was enjoying has been nuked, I dont need thousands of mesh on some parts of model (tyre surface) but need detail on screw threads on bolts and details on side wall of tyre, is there a way of reducing mesh on less important areas ?

This would be a FANTASTIC option as why do we have to wreck a model as it contains far to many faces for most of it and makes moving the model around like wading through molasses ?  :(
