Feature Requests / Photo editing the orthomosaic (Photoshop capabilities)

« on: August 14, 2024, 04:56:39 AM »

It would be amazing to have some tools similar to Photoshop to edit the final ortho mosaic so it can be more aesthetic and fix some areas of the Ortho that aren't perfect. I know there are some basic Ortho Mosaic editing tools, but in some jobs, we're always forced to export some areas to Photoshop for final editing and delivery. Editing colors, shadows, fixing edges, clone tool are some useful tools I imagine.

General / Color Calibration Phase One IXU150

« on: September 01, 2023, 03:47:21 AM »

Hi Everyone,

I processed a project from a 150 mp phase one sensor. The project is 14,000 Ha and everything is fine except for the shades of the flight lines. What's the correct procedure to remove these shades (see attached image)? Would color calibration of the Mesh do the trick? This is only visible when viewing from far away when I zoom in it can't be perceived.

General / How would the new MacStudio do with Metashape

« on: March 24, 2022, 10:42:11 PM »

Hi Everyone,

Not an apple fan boy or anything, actually the contrary, but I'm seeing these crazy benchmarks of the new Mac Studio with the M1 Ultra outpreforming anyhting at any task. Does anyone have it to test out how good it fares at processing photogrammetry datasets?

General / Orthophoto colors and artifacts error

« on: April 19, 2021, 05:17:36 PM »

Hi,

I've been having this issue mainly when I have cloudy days and the exposure varies during flight. I get this weird texture on my final ortho which aesthetically isn't adequate. Is there a way to avoid this or is there a solution? Mosaic editor won't solve the problem,  at least no most of the time.

Thanks,

Santiago

General / Thermal Reflectance Map from RJPG Images

« on: October 01, 2020, 06:56:23 PM »

Hi,

Does anyone know if I can create an accurate thermal mosaic derived from RJPG XT2 images? I need to create a Thermal mosaic for solar panel inspections, but I need the accurate thermal pixel number to be maintained in the mosaic. Has anyone managed to achieve this?

Best regards,

General / PHANTOM 4 RTK ALIGMENT ISSUES

« on: November 08, 2019, 05:14:16 PM »

Hi everyone,

I have a project were I used a phantom 4 RTK for a very rigorous client. We did every flight without truning off the base station that comes with the drone so that every flight would be logged with the same elevation. Still we're getting a huge aligment error for an important portion of the area. I've tried checking and unchecking the load accuracy form xmp data but eithewr way I get the error. Could anyone advise on what might be happening, I've already checked the rotation values and there's no apparent issues there.

General / Align new images with a bigger Project

« on: September 26, 2019, 08:21:37 PM »

Hi,

I'm having issues to align new images to a huge project I'm processing. The whole project has around 60K images so far, and I just got 2.5K new images that I need to align, but it's been impossible to align this neww images without resetting the whole project. I don't know what should be the methodolgy used but I've tried selecting around 5K images that include the new ones and the one that have already aligned and oerlap with them, then I right click and select the option align selected images with no new images aligned in the process.

Please let me know how to proceed. Right now I'm aligning the new images in another chunk, but chunk aligment has worked very poorly so far.

Best regards,

General / Rotated Region by Accident

« on: September 04, 2019, 08:08:50 PM »

Hi,

I'm working on a survey and I need to rotate the region so my bounding box can process just one zone. By accident I might have rotated the region in the X or Y axis. When I finished processing I noticed something weird on the point cloud so I zoomed to my bounding box and noticed I had some slight rotation of the region. How can I make sure my region only rotates on the Z axis or in case I rotate it over the XY axis correct it.

Best,

General / Alignment Stuck at 99% for 2 days

Hi everyone,

I'm trying to align over 30K images in agisoft. I'm getting this in teh details pane.

General / Breaklines and mass points

« on: January 24, 2019, 09:40:29 PM »

Hi everyone,

What would you say is the most precise and efficient way  of creating breaklines and mass points from UAV data sets. I normally don't do this for every project, only those were roads, creeks, rivers, mine pits and so are present, this way generating a more accurate TIN vs just working with the DSM and DTM generated. What I'm doing right now, with the resources I have, is draw polylines directly on the point cloud using agisoft and exporting this to arcmap were I generate a TIN based on those 3D polylines. This is time consuming and in some cases not as accurate as using the stereo pairs, which isn't an option with UAV data because of the amount of images generated in a flight.

I found two software that show how to create breaklines from point clouds, but really don't know how they would work in certain conditions where lots of vegetation is present. One of the is Carlson Software and the other is virtual surveyor. If anyone has worked with any of this please provide some feedback or if you have a much better aproach it would be interesting to hear about it.

I must also add that I'm not a photogrammetrist, my background is more based on GIS software but with no photogrammetry training, everything I've learned about photogrammetry has been through experience.

General / Making 3D print of a open pit

« on: August 16, 2018, 02:38:19 AM »

Hi Everyone,

I want to make a 3D print of a open mine pit. Since it's a hole and I have little to no experience with 3D models, I work Agisoft exclusively for photogrammetry purposes, I wanted to know how can I close the hole or what the approach would be to make a 3D model of this open mine pit. Is there a way with software like Mesh Lab to make walls and a floor to the model and be able to close it.

Thanks,

Santiago

General / How to avoid this effect in orthophoto

« on: June 18, 2018, 10:05:27 PM »

Hi Guys,

I've been seeing this effect whenever there's a change in light in the images. Where there are shadows and direct sunlight just between them I'm getting this effect that affects the quality of the ortho. Any way to work around it.

Best regards and thanks,

Santiago

General / Urgent! Aerial Triangulation File, Format inquiry

« on: February 09, 2016, 10:54:10 PM »

Hi,

A client is asking for the aerial triangulation files. I'm trying to figure out which files, of all the files I can export with Agisoft, are the ones he needs and how can I open them and view the AT files. Not sure if this files are the camera positions or the matches (or if some other file), which I can export by going into tools, export, cameras or matches. My client uses ArcMAP to view the files so I would need a format compatible with ArcMAP.

They didn't specify a format.

Thanks for any help and best regards,

General / Mosaic Resolution, Orthophoto Resolution

« on: October 08, 2014, 05:35:14 PM »

Hi,

I have the following issue with a very huge project I'm working on. I have over 2000 images taken between 250-400 m above terrain in a very variable terrain. The project consists on 86 km from which I made two flight lines. The terrain varies from 2000 m above sea level and goes to nearly 1000 m above sea level, if this matters. The images all have very good overlap and I've been having mainly 2 major issues.

1. I can't manage to align the images correctly although I have the GPS position for everyone of them. I haven't tried chunks because I've never worked with chunks before and I'm afraid the merging will not be as good as if I process everything in a single run, although I may be wrong. If anyone has had good experience with chunks please let me know.

2. I've managed to create 2 separate projects were all the images are aligned. Using this I created 2 mosaics, but the issue I have now is that the mosaic creation is telling me the resolution will be around 50 cm when the resolution should be between 10-15 cm or so.

I've attached an example of the image with the worst resolution during the flight and a zoom in showing the resolution it has. The final resolution should be something similar to this I believe.

If someone knows how I should approach this project please let me know.

Best,

Santiago
