PHOTOMOD History

Version 1.3 (1994)

Single stereopair processing

Central projection images

Version 2.0 (1999)

Tens, hundreds of images

Block aerotriangulation

Version 3.0 (2001)

Hundreds of images

Pushbroom satellite images processing

Semiautomatic internal orientation

Version 3.5 (2003)

Distributed network storage system

Version 4.0 (2006)

Thousands of images

Fully automatic tie points measurements

slide3

Current Photogrammetric Processing Requirements

  • Large blocks (over 10 000 images)
  • Images with high color depth (16 bit samples), multichannel (4 and more channels)
  • Stereoprocessing of any two overlapping images
photomod 5 software modules
PHOTOMOD 5. Software Modules
  • Montage Desktop

Project management

  • AT

Internal orientation, manual tie point measurements

  • AAT

Automated tie point measurements

  • Solver

Central projection and pushbroom adjustment

  • StereoModule

Stereoprocessing, combines DTM and StereoDraw

    • DTM

DTM generation and editing

    • StereoDraw

3D digitizing in stereo mode, topology, code table handling

  • Mosaic

Orthorectification and orthomosaicing

photomod 5 project management
PHOTOMOD 5. Project Management
  • Large block support (over 20 000 images)
  • Speed up global block operations
  • Integration of AT and Solver to speed up aerotriangulation, locating and correcting blunders
  • Several graphical modes
    • No graphics—for huge blocks

(recommended for blocks over 5000 images)

    • Limited graphics—for large blocks

(recommended for blocks of 1000—5000 images)

    • Full graphics—for medium size and small blocks

(recommended for blocks up to 1000 images)

photomod 5 more flexible workflow
PHOTOMOD 5. More Flexible Workflow
  • Override of fixed stage sequence while retaining clear workflow
  • Ability of stereoprocessing before completing triangulation
  • Stereoprocessing of any two overlapping images
slide7

PHOTOMOD 5. Improved Raster Images Support

  • 16 bit samples
  • Any number of channels
  • Storing rasters in source color

format inside the project

  • Selection of channels

to process at any time

  • Support of rasters

over 4 GB size

photomod 5 improved correlator
PHOTOMOD 5. Improved Correlator

Improved reliability:

  • Multichannel support
  • High color depth support

photomod 5 internal orientation
PHOTOMOD 5. Internal Orientation
  • Fully automatic internal orientation for film cameras

(using cameras library)

  • Improved graphical display of the results

(for easier detection of blunders)

photomod 5 stereoprocessing dtm stereodraw
PHOTOMOD 5. Stereoprocessing (DTM & StereoDraw)‏
  • New StereoModule: combines DTM and StereoDraw functions
  • On-the-fly TIN and contour lines
  • Big amounts of pickets

(tens of millions of points, laser scanner data)

photomod 5 distributed batch processing
PHOTOMOD 5. Distributed Batch Processing

Batch mode processing distributed over LAN:
