MATCH-T

MATCH-T stands for automation and precision in DTM generation.

"MATCH-T DSM" with new functionality for extraction of digital surface models will be available soon !!!

MATCH-T is inpho's automated DTM generation environment providing highly precise digital terrain models derived from aerial and satellite imagery. Seamless DTMs are generated for entire blocks or for any sub-block or polygon areas. MATCH-T is part of inpho's digital photogrammetric system which comes now with its new core ApplicationsMaster.

MATCH-T automatically generates digital terrain models interpolated from extremly dense 3D point clouds which are extracted from the imagery. Best accuracy is achieved by applying advanced algorithms for image matching and data filtering.

A vast variety of organizations from all over the world rely on inpho's experience in automatic DTM generation.

MATCH-T is available stand-alone, or as part of complete solutions for photogrammetric DTM generation:

DTM Box combines MATCH-T with DTMaster Stereo, inpho's powerful photogrammetric DTM editing station. DTM Box is a complete photogrammetric DTM station, including DTM data collection, quality control and editing.

ApplicationsMaster:

The components of inpho’s photogrammetric system are delivered with ApplicationsMaster, the new core of the system. It provides a comprehensive collection of basic tools for
  • project definition
  • import and export of project, image and DTM data
  • transformation into other geodetic datums and map projections
  • conversion of data and project files
  • support of numerous aerial and satellite image geometries
  • image preprocessing and orientation
  • DTM handling.
Details of ApplicationsMaster are described in the Solutions section (Digital Photogrammetry) of this website.


Features

DTM generation from aerial images (frame and line sensors), and from various types of satellite imagery (Ikonos, Quickbird, Spot, Landsat, IRS C/D, Aster).
One seamless DTM is generated for a user definable area, which can be any sub-block or polygon area, or the entire block.
Intelligent multi-image matching through on-the-fly selection of the locally best suited images for DTM generation.
Extremely dense DTM by using feature-based matching techniques.
Considers pre-measured morphological data (breaklines, 2D and 3D exclusion areas, borderlines).
Eliminates outliers, e.g. trees, houses, by robust finite element interpolation.
The project area may be subdivided into polygonal areas with individual, appropriate parameter settings for terrain type and terrain coverage.
Optimized point extraction by dynamic filtering of sensor noise.
Increased number of points in poorly textured image areas through local auto-optimization of parameter settings.
High quality terrain representation near breaklines by adaptive parallax bound strategy.
Numerous functions for internal quality control.
On-line epipolar image resampling:
 
No extra processing step
 
Necessary disk capacity reduced, no intermediate storage
The integrated DTM Toolkit provides a flexible post-processing of DTMs, with functions like merging, splitting or tiling of DTMs.
Filtering methods are available to thin-out DTM data.
DTMs can be converted into several formats, including hybrid DTMs, TIN, raster data, or point clouds and lines:
 
SCOP DTM, AutoCAD DXF or DXF-TIN, ArcGIS SHP-TIN, VRML, VRML-TIN, GeoTIFF, BIL, FLT, Winput, XYZ


Versions

MATCH-T is offered stand-alone or as part of product bundles:
 
as a stand-alone product
 
as part of DTM Box, including DTMaster Stereo
 
bundled with Summit Evolution


Benefits

MATCH-T is well-proven and production-oriented, and offers its users significant benefits:

Superior productivity through:
 
High processing speed (average 3-5 min. per image pair)
 
High level of automation
 
Minimized user interaction for project set-up
Superior quality through:
 
High accuracy by leading-edge matching techniques
 
High reliability by internal quality control
Easy integration into any third-party workflow.

MATCH-T

Automatic digital terrain model extraction is done through extremely dense feature-based matching techniques, guaranteeing reliable and accurate results.

DTM borders may be defined covering multiple images of a photogrammetric block.

MATCH-T generates regular grids or thinned-out irregular point clouds. Pre-measured morphological data is rigorously considered. Millions of automatically matched points are used for the robust interpolation of the DTM grid. Grid codes help to analyze quality and morphology.
