| − | ==Description==
| + | |
| − | | + | |
| − | In a prior step, [[PIMs]] computes depth map for each image. PIMs2Mnt merges these individual depth maps in a global digital surface (or elevation) model.
| + | |
| − | <br>
| + | |
| − | Name of this tool comes from "Per Image Matching" (PIM) and the french "Modèle Numérique de Terrain" (MNT) which is generally translated by "Digital Elevation Model" (DEM).
| + | |
| − | | + | |
| − | ==Syntax==
| + | |
| − | The basic syntax requires an argument :
| + | |
| − | <pre>mm3d PIMs2Mnt PIMsType </pre>
| + | |
| − | | + | |
| − | ===Mandatory unnamed arguments===
| + | |
| − | * string :: {Dir or PIM-Type (QuickMac ...)}
| + | |
| − | | + | |
| − | Authorized values are the same the types used with [[PIMs]] (Type in (Ground, Statue, Forest, TestIGN, QuickMac, MicMac, BigMac, MTDTmp). <br>
| + | |
| − | The chosen type must have been computed at the prior step with the [[PIMs|this tool]].
| + | |
| − |
| + | |
| − | | + | |
| − | ===Unmandatory named arguments===
| + | |
| − | * [Name=DS] REAL :: {Downscale, Def=1.0}
| + | |
| − | * [Name=ZReg] REAL :: {Regularisation, context depend}
| + | |
| − | * [Name=Repere] string :: {Repair (Euclid or Cyl)}
| + | |
| − | * [Name=Pat] string :: {Pattern, def = all existing clouds}
| + | |
| − | * [Name=DoMnt] bool :: { Compute DTM , def=true (use false to return only ortho)}
| + | |
| − | * [Name=DoOrtho] bool :: {Generate ortho photo, def=false}
| + | |
| − | * [Name=MasqImGlob] string :: {Global Masq for ortho: if used, give full name of masq (e.g. MasqGlob.tif) }
| + | |
| − | * [Name=Debug] bool :: {Debug !!!}
| + | |
| − | * [Name=UseTA] bool :: {Use TA as filter when exist (Def=false)}
| + | |
| − | * [Name=RI] REAL :: {Resol Im, def=1 }
| + | |

| − | ===Help===
| + | |
| − | A basic help can be asked with
| + | |
| − | <pre> mm3d PIMs2Mnt -help </pre> <br>
| + | |
| − | | + | |
| − | | + | |
| − | ==Workflow==
| + | |
| − | PIms2MNT is part of the new pipeline of simplified tools for dense patching and orthorectification.<br>

| − | ==Example==
| + | |
| − | An example included in the [[GrandLeez|GrandLeez tutorial]] :
| + | |
| − | | + | |
| − | <pre> mm3d Pims2MNT MicMac DoOrtho=1 </pre>
| + | |
| − | | + | |
| − | | + | |
| − | ==GUI==
| + | |
| − | As for other tools, arguments can be chosen through a GUI using the command:
| + | |
| − | vPIMs2MNT
| + | |
| − | | + | |
| − | | + | |
| − | ==Notes about DEM==
| + | |
| − | | + | |
| − | PIMs generates DEMs which can be retrieved in the file :
| + | |
| − | <pre> ...\PIMs-TmpBasc\PIMs-Merged_Prof.tif </pre>
| + | |
| − | | + | |
| − | Generated DEM '''is not recorded''' in the coordinates system, even if it is georeferenced (with a TFW file). Difference stands in a translation and scale factor : by this way, it accommodates better the limitations of floating point precision on very high precision data.
| + | |
| − | | + | |
| − | They are stored in a local system which can be transform in the initial one using parameters specified in the file :
| + | |
| − | <pre>...\PIMs-TmpBasc\PIMs-ZNUM-Merged.xml </pre>
| + | |
| − | | + | |
| − | Example of this file:
| + | |
| − | <pre><?xml version="1.0" ?>
