I agree, they should let you define a color as masking. Another idea is to let you draw a mask in the program and apply it to all photos, or a set of photos. That way you could still use JPEGs

Thanks, will try putting the new pics in a different path and changing to it

I've tried DNG files but Metashape doesn't read any of the processing information so you get very dull images. There doesn't seem to be an advantage because you can't use the greater dynamic range to adjust brightness etc. It would be great to cut Lightroom out of the workflow, and also to have a full project with raw files which can be tweaked in the future!

General / How to reload photos?
« on: May 07, 2023, 09:22:11 PM »
I use raw drone photos and edit them in Lightroom. Sometimes I re-edit further and I used to be able to just replace the photos in the project folder and the Agisoft would read them. For example, I just edited a set to increase brightness and bring up shadows. But with the current version, the program doesn't use the new photos for building the orthomosaic. It seems to be using a cached version somewhere. Is there a way to force Agisoft Metashape Pro to re-read the edited photos and use those to build the orthomosaic?

The feature to look for is # of CUDA cores. Amount of GPU memory also matters but it depends on the # of photos you process

No, because the GPS coordinates from the drone, or from control points, are in meters or feet above a datum that is projected out from the center of the earth. You would have to view your 3D model, orthomosaic, DEM, etc in software that presents the earth as a globe

I think the accuracy is really how the position data gets weighted. So maybe your XMP values are too low. If you want your resulting orthomosaic to match the GCPs, you need a low value for the GCPs and a higher value for the cameras

Are you using ground control points? And are you sure the coordinates of the GCPs are accurate?

This may seem like a minimal thing to look for, but the change of "Build Dense Cloud" to "Build Point Cloud" is fine, but now the order in the Workflow dropdown is out of order it seems and can be confusing. it is nice to have the workflow items in order of common workflow process order. Now Build Point Cloud is below Build Tiled Model.

Dear smiller,
Thank you for your feedback.

Usually, when building a model and a tiled model, users can skip building a point cloud and use depth maps as source data. Users who need a point cloud as a result usually process aerial data, after that they build DTM/DSM, Orthomosaic. Therefore, the workflow is divided into such sections and the order of commands has been changed.

I know this is off topic but could you consider having the workflow be buttons on the interface, rather than in a menu?

General / Flying manually and rolling shutter compensation
« on: January 29, 2023, 09:40:24 PM »
I fly my DJI Air 2S and DJI Mini 3 manually, and I try to get all my photos while the drone is moving forward. But sometimes I accidentally take a picture while the drone is stationary. Or I intentionally take  some photos with the drone stationary to get some different angles on a particular building or natural feature. Do I need to split these photos into a separate group so they don't get rolling shutter compensation applied?

Fly along the jetty directly above, and fly additional lines on each side of it

Do you mean you took GPS coordinates of locations on the ground without markers? You can use those as control points, you just have to place them correctly on the images

On my viewer you can see my orthomosaics made with the DEM as the base

I haven't created any orthomosaics from that many photos but what I always do is make a medium or high quality dense cloud, then create the DEM, and then the orthomosaic. I don't ever make a 3D model first, unless I want my final product to be a 3D model

General / Re: How to use GPS/INS Offset settings
« on: October 02, 2022, 10:35:57 PM »

in the case of a known fixed offset from camera  center to GNSS antenna like for example the Phantom4, the measured offset in Z is 17 cm and can be input in camera calibration if your airborne GNSS positions refer to antenna.

In case of varying barometric altitudes from DJI, this offset is variable and so using a fixed off set would not be appropriate...

Hope this makes sense!

But it's not variable, or it's only slightly variable. My thinking is that the offset at least reduces the error introduced by the massive offset in the EXIF data

From testing it seems like I was right. When I have metadata values low by 60 meters, I have to put in +60 meters in that field
