Python and Java API / read camera accuracy from image metadata

« on: March 02, 2020, 12:37:46 PM »

Dear all,

We have a phantom 4 rtk and we would like to know how to read the camera accuracy from the rtk flag. If we import the images from the metashape gui interface we don't have problems. But when we import the images from a python script the accuracy is automatically  set to a 10m.

Thanks

Python and Java API / rmse tie point image residual

« on: May 10, 2019, 07:25:04 PM »

Hi,

I have a question regarding the computation of the rmse tie point image residual (reprojection error per image!). Is there any code that I can reuse to do this computation and save it in a file?
Another question is about the installation and use of the python 3 module. Is there an installation manual? As I would like to use a dedicated IDE to develop my scripts, i suppose that this is the purpose of this wheelfile.

Thanks, Gil

General / Phantom 4 pro camera settings for mapping

« on: May 18, 2018, 11:01:33 AM »

Hi all
I'm trying to adjust manually the camera settings for my Phantom 4 pro (P4P) with the DJI Go 4 app.
If  I set the shutter and aperture value to manual mode the photos have lower quality than in the automatic mode.
Another parameter is the auto focus setting.
What are yours configuration setting that you use for mapping in general?
And for 3D modelling (for example an entire heritage building) ? How do you configure the P4P camera?

Thanks,

Gil

Python and Java API / compute image overlap map

« on: April 19, 2018, 11:41:20 PM »

I need to compute a georeferenced raster containing the image overlap. This map is generated in the report but it will be fine if it could be exprted as a raster with image quantity per pixel.
I wonder if anyone know how to compute it using python scripting?

Thanks, Gil
