Bug Reports / Transform object doesn't work

« on: August 06, 2022, 01:52:16 PM »

Hi I created model from aerial photos and I would like to cerate ortophoto from mesh. Spare cloud is rotated and X, Y and Z axis are bed. So I did Model/Transform Object/ Reset Transform because other options were greyed next I did Model/Transform Object/Rotate Object and set model correctly...after that I tried to "Update Transform" but after that model is again in bed position. I am using 1.8.3 Metashape Professional version...

Bug Reports / JPG aligned Tiff not

« on: March 02, 2020, 08:18:51 PM »

Hi
I have archaeological object placed on rotating table photographed from different angles. Usually I take photos in raw format (canon 5ds). Usually I do fast checking that everything is ok and align 144 photos, key point 40 000, tie points 9000 all other options off. ALL photos were aligned ok in RAW (I think it's JPG included in RAW). Next I converted raw photos to TIFF and changed white balance. This tiff files didn't align correctly. I tried to convert RAW files to JPG and they aligned correctly even with changed white balance. So I tried to covert RAW files straightforward to TIFF and this TIFF files always can't be aligned. I checked TIFF with LZW compression and without always with the same result - bed align.

I have such problem in 2 projects so far. I need TIFF because I want to have best quality and masks. I did a test with PNG files and they also didn't align. So the result of my short test is that TIFF files are not aligned correctly in Metashape 1.6.1. Maybe because they are to big ?  I am changing only picture format to JPG and align is correct - all photos ! All others parameters are the same.

So conclusion is that JPG files can be aligned TIFF not. I have 64GB of RAM i7 processor and RTX 2070 Super graphic card. I think computer is ready for align 150 photos.

I can align jpg files and next change the path of each file to tiff file but I have to do it one by one It takes a lot of time with 150 photos. I can provide files and project by PM if they are needed.

General / Workflow for better textures on 3d models

« on: December 28, 2017, 04:38:24 PM »

I am creating 3d models from hundreds of photos taken from different angels and distances. My main problem with this 3d models is that they have texture with difference in sharpness. Same places are sharper same are blurred. I would like to have bigger control over texture generation. I am using standard generation of texture (generic mosaic) because it gives the best quality. I am usually manually selecting photos for texture generating but it's very time consuming. I have to select photos, generate the texture check is it ok usually it's not ok so again select photos, generate the texture......etc.. Do you have any faster workflow for generating crisper texture or for changing photos from which the texture is generated in exact places of 3d models???

Bug Reports / Blank orthomosaics when orthomosaics is generated second time

Hi I have 3d model of trench and I am trying to create orthophotos of one side. Model is georeferenced with GCP from GPS. When I am generating orthomosaic for first time everything is working when I try to do that second time I get blank screen no orthophoto at all. Bug apears in 1.3.4 and 1.4 prerealese photoscan.

Feature Requests / Seamlines edit for textures

« on: February 07, 2016, 01:21:56 AM »

Hi
Is there any possibility to determine from which image the texture is generated on mesh model. I would like to change same parts of texture like I can do in seamlines edit of orthophoto.

General / 3d model of sculpture - viewing, editing, measuring...

« on: December 10, 2012, 10:52:33 PM »

Hi
I just finished presentation of 3d model of ancient sculpture created in photoscan. That's good way for presentation but not for analysing and viewing the 3d model.

Usually I am using Meshlab but maybe there is better software for measuring, editing, cutting, drawing etc. on 3d models for free or not so expensive ? Do you know any software which can be used by not experienced in 3d archaeologist in which he will have possibility to work with 3d model ?

I am also interested in methods of interactive presentation of models in Internet like flash scripts etc do you know any ?
