Python and Java API / Masked point cloud with masks on certain photos only

« on: May 27, 2024, 05:45:41 PM »

Hello,
Using the python API, I'm trying to build a point cloud using masks.

I have 10 photos but only a mask on 2 of them (too hard to make a mask automatically on the others). I import the 2 masks with chunk.generateMasks.
The mask works perfectly on the point cloud if I only use the 2 photos and their mask, but not when I add the other photos.

Is there a way to display on the point cloud only the points that are not masked on photos 1 and 2?

Thanks in advance for your help

Python and Java API / Re: How to Transform DEM with Python API?

« on: March 28, 2024, 05:29:54 PM »

Hello,
I have the same problem but I'm not sure how to use the transformRaster() function.
How to find the elevation.key for the DEM that should be subtracted from the active DEM ?
Also, do you have an example with this function (it might help me)

here is my unfinished code :

Code: [Select]

chunk.buildDem(source_data=Metashape.PointCloudData, interpolation=Metashape.DisabledInterpolation)  # first DEM
chunk.elevation.label = "Initial Elevation"
chunk.buildDem(source_data=Metashape.PointCloudData, interpolation=Metashape.Extrapolated, classes=Metashape.Ground) # ground DEM to subtract to the other
chunk.elevation.label = "Ground Elevation"
chunk.elevation = None
chunk.transformRaster(source_data=Metashape.ElevationData, subtract=True, ...)
