Build DEM with planar top XY

[ankit.chaurasia]

Hi,

I am trying to build DEM for images and marker file has been added in local coordinate system i.e EPSG::9001

I have to build DEM in planar topXY. I tried using Alexey Pasumansky code with modification for version Photoscan 1.3.2.

For DEM:

Code: [Select]

if not chunk.transform:
chunk.transform = PhotoScan.Matrix ([[1,0,0,0],[0,1,0,0],[0,0,1,0],[0,0,0,1]])

proj = PhotoScan.Matrix ([[1,0,0,0],[0,1,0,0],[0,0,1,0],[0,0,0,1]])  #Top XY

chunk.buildDem(source=PhotoScan.DenseCloudData , interpolation=EnabledInterpolation,projection=proj)

But i am getting this error:

Code: [Select]

TypeError: argument 3 must be PhotoScan.CoordinateSystem, not PhotoScan.Matrix
But documentation for photoscan api says:

buildDem(source=DenseCloudData, interpolation=EnabledInterpolation [ , projection ][ , region ][ ,
classes ][ , progress ] )
Build elevation model for the chunk.
Parameters
• source (PhotoScan.DataSource) – Selects between dense point cloud and sparse
point cloud. If not specified, uses dense cloud if available.
• interpolation (PhotoScan.Interpolation) – Interpolation mode.
• projection (Matrix or CoordinateSystem) – Sets output projection.
• region (tuple of 4 floats) – Region to be exported in the (x0, y0, x1, y1) for-
mat.
• classes (list of PhotoScan.PointClass) – List of dense point classes to be used
for surface extraction.
• progress (Callable[[float], None]) – Progress callback.

Please do help me with this.

Hello ankit.chaurasia,

Currently DEM generation via Python doesn't support planar projection option defined by the 3x3 matrix. We will fix it in the next update.
