General / Re: point cloud variance

« on: January 29, 2020, 04:26:08 AM »

If I understand correctly, the question being asked by the first poster is how to get the point cloud variance to be visible when looking at the sparse cloud.



How do I get this feature to work? I've built both a sparse and dense cloud, however neither allowed for this.

What checkbox am I missing?

Feature Requests / DEM/Dense Cloud Confidence

« on: January 29, 2020, 04:10:37 AM »

The new dense cloud confidence visualization feature is great! This seems to catch areas with very few/changing features (Flat snow & Water where I am). A way to incorporate this into DEM creation would be nice. I imagine being able to set for the DEM to only be built from points with a confidence >XX.

I'm also on board for something like this!

Feature Requests / Selected Point Statistics

« on: July 31, 2019, 12:22:49 AM »

I will commonly find an area of my reconstruction where there are many points in incorrect locations. It would be nice to be able to select these points and see their statistics quickly. I imagine a feature where in the bottom left I could see XXX,XXX points, XXX selected along with 0.XX Average reprojection  error, XXX Reconstruction Uncertanity, XX Avg image count, XX Projection accuracy.

I think being able to see this quickly would allow for more efficient use of the gradual selection tool.

It would also be very interesting to see a tool that allows for the coloring of points via these quality parameters.

General / Re: Systematic Z Error in Proportion to Altitude (Phantom 4 RTK)

« on: July 02, 2019, 08:53:37 PM »

I've found that there is significantly more noise on flat surfaces when I leave the oblique images on during dense cloud generation. This noise makes the rendered DEM's much uglier.

Python and Java API / Disable Photos With "DJI" Header

« on: May 30, 2019, 06:02:31 PM »

This is a super simple one:

I'm looking for a script that will disable all photos that have DJI in their filename. Can anyone help with that?

The key here is to take oblique photos of the area of interest. Use these for the initial alignment but disable them before dense cloud generation.

General / Re: How to use Classify Ground Points

« on: April 19, 2019, 07:52:03 PM »

My guess would be that your project isn't referenced. This means that Metashape doesn't know which way is up (Which is necessary for classifying points). Did you use ground control points or have location data for where your photos were taken from?

General / Re: Remove Coordinate Systems

« on: April 19, 2019, 07:48:51 PM »

Alexey-

One of these systems was in the user created projection section. I deleted this projection. However these additional projections still appear. I'm at a total loss as to how to eliminate them.

The key issue I am trying to solve by removing them is a shift in the point cloud upon export. When compared in external GIS software, the point cloud is out of alignment by 40-50'. I believe this is due to the wrong projection/datum transformation being used.

General / Remove Coordinate Systems

« on: April 18, 2019, 12:35:40 AM »

While working to figure out some issues I was having with coordinate systems, I created several with the same name (See attached image). All of them have slightly different datum transformation settings.  I believe this is causing issues with point cloud export...

Is is possible to remove these coordinate systems? I have tried uninstalling and reinstalling, however they reappear after the reinstallation.

Just installed it! Works like a charm! Thanks to the whole Agisoft team for being so responsive.

Feature Requests / Ability to Drag in Folders

« on: February 27, 2019, 08:46:41 PM »

It would be really nice to be able to drag in entire folders of photos from windows explorer. Currently when I try to do this I get error: "Can't open file: Access is denied (5)"

Python and Java API / Disable Photos below Certain Altitude

« on: January 28, 2019, 10:09:48 PM »

I have found that included several lower altitude oblique photos during the initial alignment increases the alignment accuracy. However, during the dense cloud reconstruction, these photos seem to significantly increase the amount of noise. Is it possible to create a script which disables photos below a certain altitude or a certain amount below the mean altitude of the loaded photos?

Python and Java API / Re: Define Bounding Box By Camera Locations

« on: December 20, 2018, 08:20:53 PM »

Alexey,

I think that would probably be a better way to do this. However my programming skills are no where near that level. I'm just a humble engineer.
