General / Why make masks why not paint out on image in white or black instead ?

« on: May 06, 2023, 09:00:19 PM »

Hi,
To stop Agisoft trying to cross reference distracting items in photos, rather than fiddle about masking those areas out then using the import masks routine and have one file for image and another for mask, and have to relate the two in a coding name thing, or create a mask in alpha channel in pshop then save image as .tiff.   and 200 images would be far bigger file size than 200 .jpg
If one instead painted out in white or black on the image the offending area and resaved the image as .jpg, same as its current file type, surely solid black or white between images would deny agisoft the ability to cross reference those areas ?
makes life simpler.
I have shots of the inside of a tractor cab and the glazing has flash reflections also I see items outside through the glazing with flash flare over them which will also confuse the hell out of Agisoft. Can I just paint out the glazing areas in white or black ?

and which is best, should I use white or is black better ?
(using solid colour, no grain in it etc)

General / Re: What are workflow steps masking in photoshop then bring into Agisoft ?

« on: May 06, 2023, 08:47:57 PM »

Hi
Anyone, ........does no reply to this mean one cannot use photoshop to mask up an image then take it into Agisoft ?
Looks that way.
 
I am familiar with photoshop and the tools are more precise and I am comfortable with them.

I am sure there are folk using Pshop to mask out unwanted areas.
Please anyone tell us the steps required.

General / What method with photoshop to edit out unwanted item in 9 of 82 photos

« on: April 13, 2023, 08:49:54 PM »

Hi,
82 good pics, but 9 need shoe or trousers removing.
I would like to use photoshop as I am extremely well practised in its tools, then add the photos to the metashape batch and align etc.

What is the procedure, pic 1 has a shoe in the background, do I make it a layer then edit out shoe leaving a tranpsarency there, do I save it with a named channel, or do I simply replace with white or black, how do I add the result to metashape ?

This has to be a common occurrence when in a museum and you photo your own shoe or leg !

PLEASE what are the steps.

what should I be producing, how to save the image and add it etc.
I know Agisoft has its own edge following tools but I am far better with photoshop.

I do not intend to edit all 91 pics  masking each one when they dont need it.

All tuts I see are about doing the entire lot.

I want the photo align to get fail on seeing a shoe ! Metashape is exceptionally easy to fail on such things.

General / Re: What is best practice if final mesh has unwanted surroundings next to it ?

« on: October 17, 2022, 02:18:36 PM »

Please anyone.

What are the exact steps to get rid of parts I can only see when mesh is made, and not have them reoccur ?

A fundamental thing when using the program but how is it done ?

General / What is best practice if final mesh has unwanted surroundings next to it ?

« on: September 22, 2022, 04:24:20 PM »

Hi,
metashape 1.8.2
I had 20 mins to photo something I had planned for 40 mins at. Even so what I have is good and perhaps enough to model from in CAD.

I have aligned photos in Photoscan, as metashape rejected 19 of them. (it most often fails on quite a few, photoscan never fails), imported the project then to Metashape 1.8.2
deleted most of the scene which was background and unwanted.
I also removed the unwanted points visible in the open parts of the object, an old window frame without glass.
next step I chose was create mesh from depth maps, skipping the Dense Point Cloud stage, its better at detail and quicker.
Result sees some background next to the item I wish to remove., also the items visible through the window frame despite deleting those points has been modelled !

Should I delete the unwanted mesh adjacent and touching the window frame then run make mesh, but surely that will look at same data source and put back in those bits.

What are the exact steps to get rid of parts I can only see when mesh is made, and not have them reoccur ?

Cheers

General / which buttons to turn on or off to view result merge chunks ?

« on: August 14, 2022, 01:14:47 AM »

Hi,

Is the result of 'merge chunks' to be viewed with the 'show aligned chunks' button on or off ?

see results attached.

following agisoft article 'manual chunk alignment'.
I have added chunk, turned on 'show aligned chunks' *layered blue icon far right of toolbar.
I see both chunks.
I had to scale down by 30% one to match size of other, rotate and align them and then one sat within the other with bits of newspaper and a shadow edge visible .
I ran merge chunks selecting 'model' (as I had made model from depth maps), not used dense point cloud at all.

result looks like the view just before I ran merge chunks !
I turn off the 'show aligned chunks' and double click 3d model in chunk 1, then look at chunk 2, and by doing a screen grab in photoshop I see no change in these two when viewing merged chunk, the messy face of chunk 2 is still there, it didnt take the better face of chunk 1. it didnt remove the newspaper,

Is the result to be viewed with the 'show aligned chunks' on or off ?

Its not taken the best of both, it probably doesnt know whats best, having no eyes as such. However its impossible to delete out the bad bits as the tool doesnt seem to have a limiter for mesh face nearest 'me' see other post.
I dont even see any movement in the meshes as I compare those photoshop screen grabs.

General / What method to limit deletion to mesh face nearest me ?

« on: August 14, 2022, 12:29:53 AM »

Hi,
a square section W shape tube.
photos set1 lying on its side for its underside , side and topside, set 2 standing upright for its 2 sides and top.
set 1 will provide the underside for set 2.

merge chunks, set 1 sees an edge with shadow and remains of newspaper, I delete the mesh BUT it is not limited to the side nearest me, however much I try to move it around my selection is seen as also being on the far face.

see attached. when I moved the object I saw the far wall had been pinked up as well !

How do we select polys on the object face 'nearest me' ?

Basic need but I fear it doesnt exist in which case in any stage of the operation, its impossible to remove the meshes that are not required and may mess up the merge chunks.

please tell me we have a way to delete on face nearest us as we will all come across this problem.

Is there a better program that can do all this bringing chinks together and editing parts away that are not needed  ? The scale tool is atrocious, 2D rotate of a chunk , no tool does that, taken ages to keep my ortho correct chunks as they were .

Is there a better prog for bringing chunks together ?

General / How does one set the scaling start point of the model resize tool ?

« on: August 13, 2022, 11:40:02 PM »

Hi,
How does one use the scale tool, placing the start point of the scale where its needed and then I presume its a drag operation.

I have two chunks open , same item one is 30% size of other, I select the 'scale model' tool (one of the drop down along with move model, rotate model.)
NOT TO BE CONFUSED WITH SETTING A MODEL SCALE, which would be useful but I cannot find that anywhere (Standard).

I have my two items with their ends together and wish to place origin of scaling at that end and make the one same length as the other.

I click to place the origin for the scale and the model grows larger, an orange line goes from my click to a square dot somewhere on its top, not at any sensible location.

I never put that dot there.

FURTHERMORE ITS GONE MASSIVE, I CANT TELL WHICH MODEL I JUST WRECKED, THERE IS NO EDIT UNDO ON RESIZING THE MODEL,  >:(WHY NOT ? I AM FORCED TO CLOSE THE PROJECT, THIS IS NOT ACCEPTABLE, WHY NO EDIT UNDO ON ENLARGING THE MODEL ?

Start again..
I try to find a way of resiting that dot which is the origin, I fail,

I google scale tool, fail, its all about setting a scale such as 1:10 or 1:1 etc....slaps face.
try to find tutorial...fail
click on help at top of screen..select search tab, type scale,,,no topics found.
contents then, find the page showing tools, it just shows the tool, nothing about it at all.

OMG..it shouldnt be this tough, its a scale tool, normally intuitive.

and I am defeated.

How does one use the scale tool, placing the start point of the scale where its needed and then I presume its a drag operation.

General / Re: Where are the video tutorials on metashape ?

« on: August 13, 2022, 11:25:15 PM »

I cannot fathom out the scale model tool, it sets the origin to some place I dont want.
Thus I need to see how to use it.
I google it, nothing, you tube, nothing, tutorials...I have just googled agisoft tutorials, there is NO RESULT LEADING US TO THESE TUTORIALS, .

I GO ONTO AGISOFT WEBSITE, SELECT TUTORIALS, again nothing takes us to these tutorials.

if it wasnt for your reply I would not see them NEITHER WOULD ANYONE ELSE.

Come on Agisoft , why hide them ? It must be made easy, . user friendly.

when one is stuck one needs help, getting stuck with metashape is bad news when help is tricky to come by.

I bet this situation will still exist in a years time.

General / help search facility says no topics found even on things that should be there.

« on: August 13, 2022, 11:09:17 PM »

Hi,
 I call up the help from top of Agisoft menu bar, I click the search tab, I type in scale and get nothing found, i type in a word i see on page 1, and get nothing found.

I type in point, no topics found, i click list topics, no topics found.


Aaaaaaaaargh !

I have yet to get it to find things I know are existing in agisoft, such as cloud or dense point cloud or depth or, and so on etc.

how are we supposed to use this help search facility ?

we have a program with no functional help function. Thats not good at all.

General / Re: Ortho where is 2D grid and a 2D rotate tool ?

« on: August 13, 2022, 10:58:48 PM »

PLEASE ANYONE ??

I AM ALIGNING CHUNKS, WE NEED A 2D ROTATE, KEEPS GOING TUMBLER 3D ON ME.

SURELY THERE IS 2D ROTATION, AN ABILITY TO RESET THAT SPHERE THING SO THE COLOUR LINES GO DOWN ITS MIDDLE AND AROUND ITS EDGE.

IF FOR SOME VERY ODD REASON AGISOFT HAVE DECIDED TO NOT GIVE 2D ROTATE TO A 2D VIEW SOMEONE PLEASE EXPLAIN.

in Rhino the developer  have agents that respond, is there no one able to answer the basics here ?

Hi Again,
 recieved a PM, there is no reply to PM option in this system, crazy as that may sound, so unable to rpely.

Hi, I have sent the photos and .psx and also .psz to Agisoft. Wait and see what they say.
I am happy for you to see it if you wish, as it will take ages to hear back from Agisoft and I am 'on this' and needing results now.
So I need to know now what to do next.

I can wetransfer it to you.

does this forum have pm system else I need your email address somehow.

You will see the lighting and image quality was very good, dSLR EOS 70D efl 17-40 lens on 40mm, acclaimed as a very good lens. speedlight 580ex bounce off the ceiling.
background was 'the lounge, somewhat cluttered. No items moved. I am so careful, so to hear that I am poor at capture, I need to know just what was poor, so as to improve.

my reference to the bitty sparse cloud was a quickly thought up term. see attached what I had (after I trim the surroundings and base away)
I didnt think it was at all bad.

General / Should two chunks see a massive size difference of same object ?

« on: August 13, 2022, 06:32:31 PM »

Hi,
I have several photo sets of the same object, taken at same time, same camera, same focal length, same lighting same everything !
one its on its side, set 1, set 2 its upright.
each has been modelled in metashape 1.8.2 in same day. using same ultra high settings, all from depth maps. (align photos then mesh from depth maps, delete base newspaper then build texture, yes I know texture was a waste of time as merge chunks does that, but I wanted to see it looking nice !)

I try for merge chunk, file append, select chunk, show aligned chunks, with them touching each other, one is 30% the size of the other, is that normal ?

I didnt expect to have to scale up the model so much.

That just doesnt seem right at all. Surely agisoft makes models roughly the same size if they are filling the photo .
