General / 3D viewer to be like any 3D program with rotate ball aligned to object ?

« on: October 11, 2021, 12:06:57 AM »

Hi,
metashape 1.7.4
I am totally perplexed with the 3D viewport. I have a wheel, I rotate it until the grass its on is at its base and the wheel is upright. I then need the rotate ball gizmo red green blue lines to be reset to suit the wheel, as it is the red line is angled as are the other two and using it the wheel goes over on an angle, one cannot use the coloured lines to rotate the object as one would in a normal 3D ortho viewport set, If I want to rotate around the wheel as one might walk around it on the grass from front to back admiring it, instead it goes off on a silly angle as if there is no gravity. I need the grid to be the grassed area. I need a top view , a front view and a side view, then I can rotate the region and bring it in to hug the wheel. One needs an ortho view in three directions to best rotate and rescale the region.
I could do this in Rhino3D in seconds. There is only ortho view, but which ortho, is that top or front or side ? I want my vehicle wheel to be front for its face with hub, side showing tyre view fwd, top for a view down on its top.
The whole thing is highly unsettling, almost brings me to tears !   

This is a 3D prog yet its basic 3D navigation is a killer, or is there a way, as I wish it was obvious.
Rhino3D has 4 viewports top, left, front, perspective. The left can be made right, the top bottom, the front back. double click one of the names and it takes up the space all 4 did, double click the name again and we are back to all four.
This is what we need here.

Help !

Bug Reports / what OS will run metashape 1.7.4 cannot see OS requirement anywhere !

« on: October 10, 2021, 03:13:51 AM »

Hi,
requirements for metashape 1.7.4 just states hardware, I have googled this and found nothing, there has to be a software spec shown as well.  but one also must know what OS is required, installing onto an OS that isnt declared compatible can cause mayhem.
I am win 7 64 bit pro. what is the last version of metashape that is known to work on such ?

General / Which video player or editor are Agisoft users using for stills capture ?

« on: August 14, 2019, 09:40:06 PM »

Hi,
 If I go the route of capturing stills from video for use in Agisoft, rather than use the inbuilt every 10th frame option, I am wondering which player or editor enables me to press a capture key capturing stills without it asking me each time for a file name and save location, and without it stopping the video playing, and it must capture same size and quality, so no jpg compression. and be able to go frame by frame backward if I miss my moment, as well as frame by frame fwd.

I am told Vegas with some coding can capture as png, is png ok or should I use bmp or tiff, if it does those.

So what progs do you find will do all this ?

General / Can photoscan & Metashape work with stills from 4K camcorder slowly panned ?

« on: July 30, 2019, 03:05:31 PM »

Hi,
a camera takes a still image perfect if shutter greater than focal length.
A camcorder when panning  is a different thing, must the stills be as perfect for photoscan or Metashape to work.
Would a 4K camcorder save taking loads of photos, would we have to extract the stills or can Agisoft work with video ?

detail of what I tried...Using an AX100E 4K camcorder by Sony, panning can look a bit jittery, even very slow panning, using 1/50 second 0db f6.8 0density filter, lighting dictated this if using 0Db gain, would a faster a shutter speed help ? but then the depth of field would suffer, or would it, are f numbers a different thing on camcorders ? It was held on wide angle throughout the sequences.

General / Should each chunk have two faces of a box in common with other chunks ?

« on: July 20, 2019, 12:32:14 PM »

Hi,
when photographing an object e.g. a long thin box each side 30mm x 350mm placed on the ground and walking around it, first sub sequence top and both sides and ends, then turn it upside down to do the underside, can that sub sequence be the underside and one side and both ends , the ends being so narrow they couldnt assist the process that well in alignment ?
Will Photoscan or Metashape recognise the one side and marry it to the first chunks side, or does it need both sides and underside photographing in that second sub sequence ?

I ask as I had a 3 side sub-sequence (top and both sides and both ends) then an underside and one side and both ends sub-sequence and merge chunks then dense point cloud and mesh build failed to create all four sides with major omissions. (Alexei has project as Leaf spring looking at, though I simplify the description to 'box' just to establish the principle)

Also Merge chunks and Align chunks, what is difference as my method D sheet doesnt feature Align chunks at all, and Merge chunks puts all images together into one chunk it says.

Thanks

General / metashape wont show jpg in add photo

« on: July 12, 2019, 07:29:28 PM »

Hi,
having firstly tried photoscan 1.2.6 and browsed to the jpg folder, added the photos there and aligned them (all ok)  I now try metashape to see if I get any failures, but it shows no jpg in the folder yet they are still there. relaunch it and try again, even choose jpg from file type list lower right but its as if the folder is empty.

unable to add photos to project.

aim it at another folder, also shows it with no files to pick from, its gone blind as it were !

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.

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.

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.

General / ultra high mesh source ultra high densepointcloud 45mins elapsed build 0%

« on: July 06, 2019, 02:51:39 AM »

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 ?

General / Duplicate chunk in Pscan 1.4.5 and see depth maps yet dont exist until metashape

« on: July 05, 2019, 11:48:21 PM »

Hi,
suprised to see when duplicating a chunk, a greyed out option to include depth map, (also key points greyed out) and ticked are dense points and model,  as they (depth maps)  dont exist until metashape why are they there ?

General / speed of depth map I thought it was faster than point cloud

« on: July 05, 2019, 03:00:30 AM »

Hi,
Metashape 1.5.3
seeing the advert of it being finer detail and faster, 9hrs v 19hr on 730 images with use of depth map,

small wheel and axle of trolley.

Photoscan 1.4.5
create dense point cloud ultrahigh setting aggressive 6.5 hrs
mesh high setting 1 hr

Metashape 1.5.3
create mesh use depth map quality ultrahigh  reprocessing done 2hrs, estimating surface 4 hrs .  so 6hrs  :(when 1.4.5 using cloud 1 hr  . 6hrs when need pc for other intensive cad work is an issue.

Whilst I will be happy if its a higher quality the 600% more time needed on meshing doesnt tally with the 9hrs  vs 19 hrs on 730 images, I only have 90 images. cuda enabled, 32Gb ddr vengeance pro ram, Intel Core i7 4790 3.6Ghz dual core:-

What settings should I be using to get a faster result than in photoscan 1.4.5 ?

I see also reuse depth in both point cloud and mesh options but unsure of if we tick that or not.

I also see mention of use sparse cloud then select sparse cloud in mesh but so far found sparse to be rough quality so not sure if I will get a super fine detail mesh from such.

Should metashape be starting off with users selecting sparse and moderate on a new project ?

General / Just what is the purpose of the region ?

« on: July 01, 2019, 07:31:34 PM »

Hi,
 I cant see mention of what the region does (its purpose) in the manual, I see how to move and resize and rotate it, but what is it for exactly ?
I would like to think it tells agisoft where to focus its attention for processing.
I see mention of it indicating orientation, not sure though if I experience that !
Could it not be used to tell agisoft to ignore all points outside of it when creating meshes ?
i.e. another version of masking ?

General / photo masking tools none work where is tolerance options ?

« on: June 24, 2019, 09:29:34 PM »

Hi,

I am having terrible experience trying to mask an image, intelligent scissors get sidetracked by lines on my grid table. it hugged the object then when it came to a grid box line it lost the edge trace and went round my inch box on the grid, then eventually I ended up with one straight red dashed line after having gone a few inches.
tried paintbrush but got lots of peculiar bits.
tried magic wand but not any better.
https://www.youtube.com/watch?v=A-N8zD6svvY  he has standard prog and uses tolerance values in magic wand options but I have Photoscan 1.4.5 and those options are missing.

I wish to follow the apply masks to tie points method, can I use photoshop instead to mask the image or two required and how do I bring this in and use it in the tie points process ? I could have masked 20 in the time it took to not even manage to mask using the agisoft tools.
