Python and Java API / optimize coverage

« on: January 25, 2019, 05:58:46 PM »

How do I apply the optimize coverage function in python API? Let's say my chunk is just called chunk. I can't call chunk.OptimizeCoverage() or something along those lines. Also, can i apply the function before the aligncameras function or after?

Python and Java API / geoid model not used or not working

« on: January 16, 2019, 06:00:26 PM »

I'm trying to include the geoid model as given on the agisoft website (egm2008-1.tif). However whatever I do the height does not change. when i look in chunk.crs.geoid_height it is always at 0.0, while i know from for instance querying the tif file itself that it should be about 45 meters in my AOI. I've tried adding chunk.crs.addGeoid(path to egm2008-1.tif) but to no use. i get the error:

1 chunk.crs.addGeoid("C:/Program Files/metashape/geoids/egm2008-1.tif")

SystemError: <built-in method addGeoid of type object at 0x0000000012C96A88> returned NULL without setting an error

looking at my chunk coordinate system it is:

chunk.crs
Out[11]: 2019-01-16 15:59:35 <CoordinateSystem 'WGS 84 (EPSG::4326)'>

Python and Java API / Re: Behavior of Document.save()

« on: January 16, 2019, 05:36:09 PM »

Hi Alexey,

It works now, i only save after building the model with a specified save location, before building the orthomosaic. I removed everything conserved to saving between starting and aligning the images. Don't know why but i don't want to touch it anymore. thanks for your reply

Python and Java API / Re: Behavior of Document.save()

« on: January 10, 2019, 08:47:37 PM »

I first save to a specific psx file, after which i only use doc.save(). i use version 1.5.0. Even though i first specified the psx file, everytime i use the simple doc.save later in the process i get
Error: Can't create file: Access is denied (5): C:/Program Files/metashape.tmp

for some reason it is not remembering that i did specify a doc.save before. as also stated in other topics, when i give the path as an argument everytime i use doc.save i end up with an empty project. So what do i do here?

General / photoscan dem interpolation

« on: October 19, 2017, 10:57:15 AM »

The current classification method for photoscan for ground points is not good enough for me so i need to use external software. I cannot import a classification back into photoscan. However, i cannot find a better looking DTM interpolation from the point cloud than photoscan has. This is in my opinion not simply an IDW, is there any possibility that anyone can tell more about the method used by photoscan to go from dense cloud to DEM (kriging, multi-neighbourhood IDW)?
