Python and Java API / False color export with MicaSense camera (python)

« on: January 21, 2019, 12:01:14 PM »

Hello,

I am trying to export a False Color orthomosaic from a MicaSense flight campaign, using the python API.

In the interface, I am able to do this:

• Tools => Set Raster Transform => Transform tab => load three bands (B3/10000, B2/10000 and B1/10000
• Tools => Set Raster Transform => Palette tab => choose False Color from the dropdown

If I want to transform this in Python code, I end up with something like this:

chunk.raster_transform.formula=["B3/10000","B2/10000","B1/10000"];
chunk.raster_transform.palette = "False Color";
chunk.exportOrthomosaic("D:/test.tif", raster_transform=PhotoScan.RasterTransformPalette);

However, selecting the palette does not seem to work here. In the API, I notice the following keywords in the RasterTransform definition:

• false_color => list of false color channels
• palette => dict object type

But I am not sure how to use them here.

Thanks for looking into this.

Best regards,
Pieter-Jan

Python and Java API / Set coordinate system to WGS 84 + EGM96

« on: November 27, 2018, 02:18:44 PM »

Hello,

In the interface of PhotoScan (version 1.4.4), it is possible to set the coordinate system to WGS 84 + EGM96 (see attached image). Since there is no corresponding EPSG code for this (correct?), I am not able to set this through the python API.

Is there another way of doing this? I tried the following:

Code: [Select]

chunk.crs = PhotoScan.CoordinateSystem("EPSG::4326")
chunk.crs.addGeoid("C:/Program Files/Agisoft/PhotoScan Pro/geoids/egm96-15.tif")
chunk.updateTransform()
But got the following error:

Code: [Select]

Thanks for checking this out.

Python and Java API / Export Photo Thumbnails

« on: September 21, 2018, 12:31:08 PM »

Hello,

Is there a way to export or to access the image thumbnails as generated by PhotoScan? In the API document, I see the option to list the thumbnails, but not to save or get the resulting paths.

Best regards,
