MATCH-AT
MATCH-AT - the synonym for accuracy, reliability and productivity.
MATCH-AT provides highly precise automatic digital aerial triangulation based on the advanced and unique image processing algorithms by inpho. MATCH-AT is part of inpho's digital photogrammetric system which comes now with its new core ApplicationsMaster.
All the processing steps of MATCH-AT are fully automated for achieving highest productivity. The workflow is logical and easy from the project setup, the precise multi-ray tie point matching and integrated bundle adjustment, up to the block analyzing with excellent graphical support.
MATCH-AT is available in two different versions, MATCH-AT (for frame images) and MATCH-AT Pushbroom (for line sensors). The new pushbroom triangulation module directly references the raw data of the imaging sensor and navigation units.
There is a rigorous support for GPS and IMU data, including calibration of boresight misalignment, as well as shift and drift corrections.
An integrated multi-window stereo module is at hand for both, comfortable stereoscopic verification as well as measurement of control points and additional tie points.
With its advanced sub-block handling MATCH-AT is designed for processing the most demanding photogrammetric projects with block sizes of 20000 images and even more.
Due to its flexible data exchange capability MATCH-AT easily integrates into the workflow of any third-party photogrammetric system.
“Match AT has been such a very welcome and effective tool for us. I would like to think of it as "Kucera's little secret"…”

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.
 | Single, automated process for point selection, point transfer and measurement, along with an integrated robust bundle block adjustment requires minimum user interaction. | |
| Support of any film or digital frame sensors (nadir and oblique). | |
| No limitations for block size, shape or overlap. With sub-block handling (see below) projects with block sizes of 20000 images and even more can be processed. | |
| Tie points are automatically collected in image areas best contributing to the strength and quality of the block. Von Gruber positions can be used, or other patterns in case of special image overlap situations. | |
| High precision tie point correlation (˜0.1pixel) is achieved by an advanced combination of feature-based and least-squares matching, with multi-threading support. | |
| Effective tie point matching also in poorly textured, as well as mountainous areas. | |
| Strong internal quality control of tie points by performing robust bundle block adjustment in each level of the image pyramid. | |
| Flexible weighting schemes for all types of observations. | |
| Multi-camera support in one block, and camera-specific self-calibration parameter sets (12 or 44 parameters). The results of self-calibration are made available as a dense correction grid for camera re-calibration and for further use in any subsequent applications. | |
| Fully automatic interior orientation: | | |
 | Automatic detection of fiducial marks | | | |
| User definable fiducial mark templates | | |
| Project-wide photo display with correct topology, and auto image-selection for interactive, guided control point measurement. | |
| Advanced sub-block handling: | | |
| Sub-blocks make it easy to administrate, visualize and analyze large blocks | | | |
| Free block adjustment, i.e. sub-blocks can be adjusted without control points | | | |
| Sub-blocks can be merged for final project-wide block adjustment | | |
| GPS data handling with shift & drift determinaton. | |
| IMU data handling: | | |
| Preprocessed GPS/IMU data from POS AV/POSEO by Applanix and AEROControl by IGI | | | |
| Attitude data are used as constraints in the integrated block adjustment | | | |
| Boresight misalignment calibration | | |
| Optionally the triangulation can be made in a local space rectangular coordinate system for avoiding tensions caused by map projections. | |
| Powerful graphical block analyzer: | | |
| Easy visual checking of large data sets | | | |
| Visualization of image footprints, overlaps, ground control and tie points, point and photo connections, residuals, error ellipses and more | | |
| Smooth transfer of exterior orientation data to stereoplotters (e.g. Summit Evolution) and other photogrammetric applications, such as OrthoMaster or MATCH-T. | |
| Export/import formats: | | |
| DAT/EM Summit Evolution, BAE Socet Set, Z/I project, Aviosoft Ori, ABC-PC, AP32, Phorex/Pex, PATB, Bluh, Bingo | | |

MATCH-AT is well-proven and production-oriented, and offers its users significant benefits:
| Superior productivity through: | | |
| High processing speed (10–20 sec./image) | | | |
| High level of automation | | | |
| Multi-threaded processing for efficient use of multi-core CPUs | | | |
| Minimized user interaction for project set-up and data post-processing | | |
| Superior quality through: | | |
| High accuracy by leading-edge matching techniques | | | |
| High reliability by unparalleled multi-fold tie point connections, also between photo strips, and by effective quality assurance methods | | |
| Easy integration into any third-party workflow | |
MATCH-AT provides unsurpassed profitability and quality in any aerial triangulation project.
