StereoFramework otbcli_StereoFramework Stereo Framework Stereo Compute the ground elevation based on one or multiple stereo pair(s) ParameterMultipleInput input.il Input images list The list of images. False ParameterString input.co Couples list List of index of couples im image list. Couples must be separated by a comma. (index start at 0). for example : 0 1,1 2 will process a first couple composed of the first and the second image in image list, then the first and the third image . note that images are handled by pairs. if left empty couples are created from input index i.e. a first couple will be composed of the first and second image, a second couple with third and fourth image etc. (in this case image list must be even). True ParameterNumber input.channel Image channel used for the block matching Used channel for block matching (used for all images) 1 ParameterNumber elev.default Default elevation This parameter allows setting the default height above ellipsoid when there is no DEM available, no coverage for some points or pixels with no_data in the DEM tiles, and no geoid file has been set. This is also used by some application as an average elevation value. 0 ParameterNumber output.res Output resolution Spatial sampling distance of the output elevation : the cell size (in m) 1 ParameterNumber output.nodata NoData value DSM empty cells are filled with this value (optional -32768 by default) -32768 ParameterSelection output.fusionmethod Method to fuse measures in each DSM cell This parameter allows choosing the method used to fuse elevation measurements in each output DSM cell max min mean acc 0 OutputRaster output.out Output DSM Output elevation image ParameterSelection output.mode Parameters estimation modes fit user 0 ParameterNumber output.mode.user.ulx Upper Left X Cartographic X coordinate of upper-left corner (meters for cartographic projections, degrees for geographic ones) 0.0 ParameterNumber output.mode.user.uly Upper Left Y Cartographic Y coordinate of the upper-left corner (meters for cartographic projections, degrees for geographic ones) 0.0 ParameterNumber output.mode.user.sizex Size X Size of projected image along X (in pixels) 0 ParameterNumber output.mode.user.sizey Size Y Size of projected image along Y (in pixels) 0 ParameterNumber output.mode.user.spacingx Pixel Size X Size of each pixel along X axis (meters for cartographic projections, degrees for geographic ones) 0.0 ParameterNumber output.mode.user.spacingy Pixel Size Y Size of each pixel along Y axis (meters for cartographic projections, degrees for geographic ones) 0.0 ParameterSelection map Output Cartographic Map Projection Parameters of the output map projection to be used. utm lambert2 lambert93 wgs epsg 3 ParameterNumber map.utm.zone Zone number The zone number ranges from 1 to 60 and allows defining the transverse mercator projection (along with the hemisphere) 31 ParameterBoolean map.utm.northhem Northern Hemisphere The transverse mercator projections are defined by their zone number as well as the hemisphere. Activate this parameter if your image is in the northern hemisphere. True ParameterNumber map.epsg.code EPSG Code See www.spatialreference.org to find which EPSG code is associated to your projection 4326 ParameterNumber stereorect.fwdgridstep Step of the deformation grid (in pixels) Stereo-rectification deformation grid only varies slowly. Therefore, it is recommended to use a coarser grid (higher step value) in case of large images 16 ParameterNumber stereorect.invgridssrate Sub-sampling rate for epipolar grid inversion Grid inversion is an heavy process that implies spline regression on control points. To avoid eating to much memory, this parameter allows sub-sampling first the field to invert. 10 ParameterSelection bm.metric Block-matching metric ssdmean ssd ncc lp 0 ParameterNumber bm.metric.lp.p p value Value of the p parameter in Lp pseudo-norm (must be positive) 1 ParameterNumber bm.radius Radius of blocks for matching filter (in pixels) The radius of blocks in Block-Matching (in pixels) 2 ParameterNumber bm.minhoffset Minimum altitude offset (in meters) Minimum altitude below the selected elevation source (in meters) -20 ParameterNumber bm.maxhoffset Maximum altitude offset (in meters) Maximum altitude above the selected elevation source (in meters) 20 ParameterBoolean postproc.bij Use bijection consistency in block matching strategy use bijection consistency. Right to Left correlation is computed to validate Left to Right disparities. If bijection is not found pixel is rejected. True ParameterBoolean postproc.med Use median disparities filtering disparities output can be filtered using median post filtering (disabled by default). True ParameterNumber postproc.metrict Correlation metric threshold Use block matching metric output to discard pixels with low correlation value (disabled by default, float value) 0.6 ParameterRaster mask.left Input left mask Mask for left input image True ParameterRaster mask.right Input right mask Mask for right input image True ParameterNumber mask.variancet Discard pixels with low local variance This parameter allows discarding pixels whose local variance is too small (the size of the neighborhood is given by the radius parameter) 50 ParameterNumber ram Available RAM (Mb) Available memory for processing (in MB) 128
