Python with PhotoScan.RasterTransformValue

[ruadi]

Hi there,
I try to use raster-transforms, actually to export NDVI-Orthos.
When I run my script, a RunTimeError occurs, when exporting the ortho
Without "raster_transform = PhotoScan.RasterTransformValue", everything works fine.
Do I use the wrong syntax ?

Thanks, Ruedi

               self.chunk.raster_transform.calibrateRange()
               self.chunk.raster_transform.enabled = True
               self.chunk.exportOrthomosaic(saveOrtho, image_format = PhotoScan.ImageFormatTIFF, raster_transform = PhotoScan.RasterTransformValue)

Hello Ruedi,

Can you please specify, which filename is used in saveOrtho variable?

I'm not able to reproduce the issue on random project with the orthomosaic, executing the lines from your post:

chunk = PhotoScan.app.document.chunk
chunk.raster_transform.formula = ["(B4-B2)/(B4+B2)"]
chunk.raster_transform.calibrateRange()
chunk.raster_transform.enabled = True
saveOrtho = "D:/ortho.tif"
chunk.exportOrthomosaic(saveOrtho, image_format = PhotoScan.ImageFormatTIFF, raster_transform = PhotoScan.RasterTransformValue)

everything worked fine.

Hi Alexey,

variable "saveOrtho" contains: /Volumes/FastWork/PGResults/WSL/eBee/Sequoia/Sequoia_2017_11_01_v1.4.0_hMatch_proj_v1.4.0_hMatch_hDens_moFilt_ortho.tif


I used the same scripting classes for hundreds of successful process results.
When I use "raster_transform = ...", the export always fails,  without  "raster_transform = ...", everything works without RunTimeError and I get a correct exported orthophoto-product, exported report, exported points.
Using the saved project and afterwards manual export of the ortho with NDVI colors (via raster calculator) works!

Hello Ruedi,

Is this issue reproducible on the single dataset only?
