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)'>

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)?
