General / Re: Best Tiled Model setup

« on: October 13, 2025, 09:45:15 AM »

Hi, my problem is that I would like to get a much better tiled model from what I am getting right now. Since I am using both Metashape and ContextCapture in my company, 3D model looks much better with ContextCapture, but for everything else I prefer Metashape. Is there a chance to get the same or better Tiled model than what I am getting with the ContextCapture? Metashape is No1, much, much better photogrammetric software than Context. With Context I am having unsolvable problems with two cameras, while Metashape solves that with ease.
Best regards,
Darko

General / Best Tiled Model setup

« on: October 08, 2025, 08:20:26 PM »

Hello everyone,
Just looking for suggestions how to get the best possible Tiled 3D model for the large data set of the whole city. What is better, use Depth Maps or Point Cloud? Quolity level, Tile Size and what Face Count? What type of Depth filtering and should I enable Gosting filter? Is it possible to get better texture?

Hi Alexey,
Can we have a list of the useful TWEAKS, please?

General / Re: Double Sony ILX-LR1

Hello guys, thak you for your previous comments, it helped me a lot.

I did it. The project is successfully finished, and the results are perfect. I have used two Sony ILX-LR1 cameras positioned in front of each other, hinged on a single two-axis gimbal.  Each camera has been leaned 15 degrees left and right from the nadir point. I have used 50mm Zeiss Loxia lenses with the aperture set to 8, and the exposure time has been set to 1/1250. It's all been set to manual, but the ISO setting was Auto. The lens has been taped so the rings could not be rotated. It all returned fine and sharp pictures that were good for the Agi alignment procedure. Since the exposure was taken by the external timer for both cameras simultaneously, only one event was recorded for the camera pair. Some problems did appear since cameras didn't have the same number of photos (a few only) in each flight for an unknown reason. That's been solved by time comparison taken from the EXIF and events.
I have flown 700m AGL, and the flight speed was about 35-45m/s, the exposure timer was set to 1.6 sec, which gave a good overlap of 70-80%. Ground resolution was about 5cm, and the adjustment gave me errors in mm. The 3D model in TLS came out just perfect.

The complete setup is hung on the two-axis gimbal. Have no better idea of how to handle a steep climb of 30° when the plane can climb just 10°. The area that we must fly over is huge. The planned flights with a side overlap of 70% is about 4000 km. No way to use something like a small drone. We have M300 and M350 equipped with the P1 cameras and one M3E. The plan is to cover the area with the manned aircraft and later just fill in the populated places with the drones. The job is in the north Adriatic, Island of Cres, Lošinj, and a few smaller ones. I've done smaller Islands like Susak, Ilovik, etc. with the M3E with fine results but Cres is too big with no roads or places to take off with the drone and regulations are the problem as well.
Some other company have already made that aerial shooting for us on some other bigger islands and they also used a professional strictly rigid double camera flown on 1000+m AGL. The results were good. The price of one flight covers the price of all our equipment and maybe the used small airplane. For this job, we have a rented one with the pilot and I have invested in their Auto Pilot that's been installed and tested.

We are planning to make a smaller single-flight test and if that comes out fine, good. If not the option is a single camera with 50mm Zeiss Loxia lens and flight on 700m AGL.
Best regards

And, my flight is 1100m AGL.. Which is much safer than 280m that we used to fly with Loxia 21mm. Results were fine but the terrain was much more even and easy to follow.

Thanks, JMR,
I appreciate your opinion. The 85mm has been used for flights with manned aircraft (ultralight) and a ground resolution of 5cm. The 85 has been used to avoid large changes in ground resolution since the terrain is very uneven and it is hard to follow it precisely. Two cameras will be used just to get a wider swath with the single flight line. With two cameras I can cover about 850m instead of 475m and the distance between my flight lines changes from 150 to 250m (70% side overlap) which is significant.
What do you think about that?

Hi,
I am planning to use two Sony ILX-LR1 cameras equipped with Zeiss Loxia 85mm lens in simultenious triggering mode. The cameras will be rigidly mounted one in front of the other and leaned from the vertical axis for 10 deg left and right. The planned overlap between cameras will be about 10%. Is it an acceptable way of widening the field of view? In case I can use it in such a way my field of view would be 44 deg instead of 24 that has a single camera, is this OK?
Best regards,

Yes, you must be right. The only problem is that it takes days for alignment and that's why I have chosen the lowest setup. I'll redo it again and wait for a week and see the results. Do you have any suggestions for the alignment setup?
Since I have estimated coordinates for my cameras that are somewhat good, what do you think about including those coordinates in the alignment process? The first alignment was done without camera coordinates, just GCP's.

Hello,

Have you tried to draw lines and points in Agisoft Viewer? Import the 3D tls model (created and exported by Metashape) , create an active vector layer, and draw whatever you want using the underlying 3D Tls model . Later just save the layer in DXF and here you are, in CAD program again.

The other way I am doing it is Virtual Surveyor, google it.

General / Orthomosaic missalignement

« on: November 21, 2024, 04:52:32 PM »

Hi,

I have a serious problem with the huge job that consists of 50.000 61Mpix photos. Alignment has been done with the Lowest setting and only 4000 Key and Tie points. Since I had a problem with my GNSS for that procedure I've used 150 CP's. It took 3 days to finish it resulting in 10.000.000 points in sparse cloud which was managable. The problem appeared in Orthomosaic with some misaligned lines on the roads that I couldn't patch.
Is there some simple procedure to align those unpatchable parts?

Best regards,
Darko

Hello,
I have the same problem since my latest project is on the seashore I would like to select all the points with elevation lower than, let's say, -1m. Since the points are on the seafloor I would like to erase them.  Any idea?
Best,

Is there a function that would allow us to continue the old polyline or snap to point, endpoint, or any vertex?

Agisoft Viewer / NEW PRODUCT

« on: June 13, 2024, 04:29:08 PM »

Dear Alexey,

It is a shame to have such a fine Viewer and not to add more possibilities.  Why don't you make some new product like Agisoft 3D Editor for 3D model vectorization with better CAD functions and sell it separately? I know that there is a lot of functionality in Metashape but Viewer works so neat and fast that it would be much better for drafting and editing of vectors in such an environment.
Have you ever thought about that?

Best regrads,
Darko

Thanks, Aleksey.

You were right, it's been solved in this latest version.
