Python and Java API / Image channel for estimateImageQuality

« on: April 22, 2018, 01:09:33 PM »

Hello,
is it possible to specify the channel PhotoScan.Utils.estimateImageQuality(...) uses?

My script looks like this:

Code: [Select]

...
chunk.addPhotos(photos)

chunk.primary_channel = 4

for camera in chunk.cameras:
    quality = PhotoScan.Utils.estimateImageQuality(camera.photo.image())

    if quality < 0.7:
        camera.enabled = False
...

However estimateImageQuality seems to operate on channel 0 instead of channel 4.

My primary goal is to disable all photos with a quality lower than 0.7.

Best regards,
Torben

General / Orthomosaics from DEM are not correct

« on: March 16, 2018, 11:49:15 PM »

Hello,

I'm having a probem with the orthomosaics generated with dem as surface looking like the attached image.
When using the mesh as surface everything works fine...

The workflow is pretty standard:
Add Photos -> Align Photos -> Import markers -> Convert Reference to another EPSG system -> Place markers on images -> Optimize Cameras -> Build Dense Cloud -> Build DEM -> Build Orthomosaic.

Any idea what is going on here?

Best regards,
Torben

Python and Java API / Can't build DEM in python script

« on: February 20, 2018, 04:52:54 PM »

Hello,
whenever I try to call buildDem on chunk, a runtime error occures. I'm using Photoscan 1.4 btw

Here is the console output: https://pastebin.com/2yHgkVaY

And here is what my script does: https://pastebin.com/PQ4diYX7

I'm saving the project before calling buildDem as you can see. "RuntimeError: Empty frame path
" doesn't seem to be documented anywhere.

Am I missing something here? Or is this a bug?
