General / Re: PPP and shifting camera position or output position with RTK m300

« on: April 09, 2024, 10:36:39 PM »

Hi Jake

Agree with Paul.

I would add that if you establish a good base position (via PPP) prior to using the base for RTK for your drone. The correction will be applied to the camera positions in real time.

If you are correcting your base after your drone flight, then you will need to also correct the camera locations. Emlid Studio can do that for you.

When you subsequently fly the same project in different seasons, if you can use your same corrected base position, then no corrections necessary.

The important thing is to get a good base position established.

It seems to be some form of mask.  I get the same behavior with a breakline.   If I turn off the display of shapes, the red masks remain. 

If I change FILL parameter values, you can see that the surface is changing under the mask.  So, the FILL function is probably working.  But for some reason, this RED MASK is also generated over the shape.

Here is a screen recording:

DEM and the polygon both state WGS84.  The shape vertices seem appropriate.

Hi Paul.

Trying other parameters doesn't seem to make a difference in this case, unfortunately.

Referencing this article  (https://agisoft.freshdesk.com/support/solutions/articles/31000164388-dem-editing-tools),  I get different behavior.

1. Draw Polygon
2. Open context menu and select DEM > Fill
3. The polygon fills with RED.

 I must be missing a simple step to get the behavior illustrated in the article?

Thanks,

What ever I'm doing wrong, I'm consistent. A quick look at various projects using a P4P and Evo 2 exhibit similar results.

If you say so, I'm sure I do.  I don't know much about them.  The check point errors are reasonable. So, what can I do to identify what is causing the problems?

Oh, I do get a blank white plot.  I was assuming that there was no plot at all by comparison to what you were getting.

Hi Paul.

How are you able to get distortion plots for anything but Residuals? 

My residuals plot looks quite different.  Were your images captured with dewarp on or off?

Interesting conversation. 

My M3E images are captured with Dewarp off, and pre-calibration taken from XMP data via MS preferences. 

I get no values populated for K4. And I only have distortion plots available for Residuals.  Nothing for the other fields.

When I use Optimize Cameras, K4 is left unchecked, as well as b1 and b2.

Is this not the correct approach with the M3E?

General / Re: Import .csv marker file

« on: March 07, 2024, 04:31:41 AM »

Hello dpitman,

The request is quite different from the Import CSV functionality, Clayton requires to import markers' projections (2D coordinates in pixels on the images) rather then XYZ coordinates in the global coordinate system.

Ah, my mistake.  Sorry for the interruption.  Would the purpose be to try and eliminate the step in MS of adjusting the marker coordinate to the target in the image?  If so, that would not cause any reduced ability for MS to optimize cameras? The image pixel value would produce the same result as the manual point adjustment procedure?

Thank you!

Metashape allows for a marker input by Metashape .xml, not at all by .csv.  The really confusing thing is it seems like the .xml version should be attempting a universal export that most softwares could understand.

Hi Clayton.

Metashape can import .csv perfectly well without any scripting.  I am not sure why it does not work for you?
