A patch reconstruction is accepted as a success and

kept if its associated photometric consistency measure

is above this threshold. Default: 0.7
|

--pmvs-wsize <positive integer>
|

pmvs samples wsize x wsize pixel colors from each
|

image to compute photometric consistency score. For
|
||||
example, when wsize=7, 7x7=49 pixel colors are sampled
|

in each image. Increasing the value leads to more

stable reconstructions, but the program becomes

--use-3dmesh Use a full 3D mesh to compute the orthophoto instead

of a 2.5D mesh. This option is a bit faster and

provides similar results in planar areas.
|

--skip-3dmodel Skip generation of a full 3D model. This can save time

if you only need 2D results such as orthophotos and

DEMs.
|
||||
--use-opensfm-dense Use opensfm to compute dense point cloud alternatively
|
||||
--ignore-gsd Ignore Ground Sampling Distance (GSD). GSD caps the
|
||||
maximum resolution of image outputs and resizes images
|
||||
when necessary, resulting in faster processing and
|
||||
lower memory usage. Since GSD is an estimate,
|
||||
sometimes ignoring it can result in slightly better

image output quality.
|

--smvs-alpha <float> Regularization parameter, a higher alpha leads to

smoother surfaces. Default: 1.0

--smvs-output-scale <positive integer>

The scale of the optimization - the finest resolution
|

of the bicubic patches will have the size of the

respective power of 2 (e.g. 2 will optimize patches
|

covering down to 4x4 pixels). Default: 2
|

--smvs-enable-shading
|
||||
Use shading-based optimization. This model cannot

handle complex scenes. Try to supply linear images to
|
||||
the reconstruction pipeline that are not tone mapped
|
||||
or altered as this can also have very negative effects

Oct-tree depth at which the Laplacian equation is

--mesh-neighbors <positive integer>
|

Number of neighbors to select when estimating the

surface model used to compute the mesh and for

statistical outlier removal. Higher values lead to

smoother meshes but take longer to process. Applies to

--mesh-resolution <positive float>
|

Size of the interpolated surface model used for

deriving the 2.5D mesh, expressed in pixels per meter.
|

Higher values work better for complex or urban
|

terrains. Lower values work better on flat areas.
|

Resolution has no effect on the number of vertices,
|

but high values can severely impact runtime speed and

memory usage. When set to zero, the program

automatically attempts to find a good value based on

the point cloud extent and target vertex count.
