SETSM 3.4.3 released!!

New version 3.4.3 of SETSM is updated for solving following issues from 3.4.0 and 3.4.2.

(1) Memory segmentation issues

  1. Out of memory issue in relative RPCs bias computation step with new matching cut algorithm (3D voxel)
  2. Out of memory issue for 50 cm DEM generation

    * Maximum DEM size for single large DEM file in BW system (64GB) is 20 km  by 35 km (reference size). Big-geotiff file structure applied.

    * Larger DEM than reference size is split into several DEMs based on system physical memory size. The split DEMs have 200m overlapped area.

    * In case of split DEMs, ‘DEM_splited.txt’ file that is describing each split DEM information similar to ‘*meta.txt’ is in output folder

  3. Tile processing applied in orthoimage generation step to reduce physical memory size.
  4. Optimization in Local Surface Fitting(LSF) algorithm to reduce physical memory size : Both single large DEM and split DEMs for 50cm have no issues.

 

(2) Matchtag issue : New matching structure with 3D voxel scheme had a minor issue and lost some matching points.

(3) Other sensor segmentation fault issue : Pleiades sensor had an issue to read its sensor information correctly. Now the bug is fixed and working well.

SETSM 3.4.0 released!!

  1. Improvement of running time
    SETSM is improved to reduce its running time :  30 % and 15 % reduction for 2m and 8m DEM processing, respectively.
  2. Changes of SETSM basic command for applying multiple matching techniques in next version
    Please use following command for the update version ( see Manual)
    ./setsm -image [image1path] -image [image2path] -outpath [outpath] -options

SETSM 3.3.2 released!!

  1. SETSM outputs are converted binary files into GeoTiff files
  2. If someone would like to use binary files as output, please do not use this version. The updated version does not support the binary output anymore.
  3. SETSM development continues based on this update version of 3.3.2, so recommend to use the updated version for getting updated features.

SETSM 3.3.1 released!!

New features of post-processing modules

  1. Local Surface Fitting smoothing for removing severe height variation over smooth surfaces due to poor stereo geometry or sensor orientation.
  2. New matchtag information from older version of SETSM DEMs.

 

Updated

  1. Reduce the issues of small size blunders such as divots and holes.
  2. Adaptive matching kernel size from iteratively updated surface information (reduce small size blunders)
  3. New matchtag information from new decision strategy of matched points : it helps water surface and clouds filter out.
  4. meta file information update
