</head><body><h1>DisparityMapToElevationMap</h1><h2>Brief Description</h2>Projects a disparity map into a regular elevation map<h2>Tags</h2>Stereo<h2>Long Description</h2>This application uses a disparity map computed from a stereo image pair to produce an elevation map on the ground area covered by the stereo pair. The needed inputs are : the disparity map, the stereo pair (in original geometry) and the epipolar deformation grids. These grids have to link the original geometry (stereo pair) and the epipolar geometry (disparity map). <h2>Parameters</h2><ul><li><b>[param] -io</b><string> This group of parameters allows setting the input and output images and grids.. Mandatory: True. Default Value: "0"</li><li><b>[param] -step</b><float> Spacing of the output elevation map (in meters). Mandatory: True. Default Value: "5"</li><li><b>[param] -hmin</b><float> Minimum elevation expected (in meters). Mandatory: True. Default Value: "0"</li><li><b>[param] -hmax</b><float> Maximum elevation expected (in meters). Mandatory: True. Default Value: "100"</li><li><b>[param] -elev</b><string> This group of parameters allows managing elevation values. Supported formats are SRTM, DTED or any geotiff processed by the DEM import application. Mandatory: True. Default Value: "0"</li><li><b>[param] -ram</b><int32> Available memory for processing (in MB). Mandatory: False. Default Value: "128"</li></ul><h2>Limitations</h2>None<h2>Authors</h2>OTB-Team<h2>See Also</h2>otbStereoRectificationGridGenerator otbBlockMatching<h2>Example of use</h2><ul><li><pstyle=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">io.in: disparity.tif</p></li><li><pstyle=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">io.left: sensor_left.tif</p></li><li><pstyle=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">io.right: sensor_right.tif</p></li><li><pstyle=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">io.lgrid: grid_epi_left.tif</p></li><li><pstyle=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">io.rgrid: grid_epi_right.tif</p></li><li><pstyle=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">io.out: dem.tif</p></li></ul></body></html>
