-fc file.fc
This option specifies a file from which the camera
intrinsics corresponding to a range grid can be obtained.
The file should contain four numbers separated by spaces:
fx fy cx cy.
The numbers are such that the ray through a point projecting
to pixel (x, y) is given by
[-(x-cx)Z/fx,
-(y-cy)Z/fy, Z].
-lambda l
This is the geometry weight, and ranges from 0 to 1. Large
values cause the optimization process to favor the
original position measurements. Small values give more
importance to the normal estimates instead. The default
value is 0.1.
-blambda b
Same as -lambda, but for boundary points. If you don't
trust your boundary position estimates, you can lower their
confidence. Alternatively, you can use mesh_filter
and erode the mesh to eliminate them.
-fixnorm s[:n]
Invokes the normal correction stage. This step is
not executed implicitly. The parameter s
gives the radius of the smoothing kernel, in multiples of
the median edge length. The smoothing process can be
repeated n times. After smoothing and merging, the
corrected normal field contains the low-frequencies from the geometry and
the high-frequencies from the measured normals.
-smooth s[:n]
Smooths the measured positions. The parameter s
gives the radius of the smoothing kernel, in multiples of
the median edge length. The smoothing process can be
repeated n times. Smoothing is optional and can be used to
eliminate high-frequency noise from the geometry prior to
optimization.
-opt
Explicitly invokes the geometry optimization stage.
Optimization is run on the current geometry and normal
field, which depend on prior optimization, normal
correction and smoothing operations. This stage is executed implicitly
unless the option -noopt is used.
-noopt
Prevents the program from running the implicit geometry
optimization step. This can be used, for example,
if you want to save the results of the normal correction
stage without optimizing the geometry. Don't forget the
"norm:" prefix to the output file name if you want the
results to contain normals.
-noconf
Remove per-vertex confidence values. If confidence
values are present, the position optimization stage uses
them as multiplicative weights. If removed prior to
optimization, the confidence values are naturally ignored.
-nogrid
Triangulates the range grid into explicit triangles.
This is provided just for convenience.
[outfile]
The output file name. By default, normals are
not saved. To get normals, prefix the file name
with 'norm:'. For example,
'norm:output.ply' will save results, including
normals, into the file 'output.ply'.
