Software overview  

SeaGIS does not just sell software. Our software products are built on more than 10 years of development, experience and feedback from our world-wide customer base. Software products continue to be developed, typically driven by collaboration with customer research ideas and feedback. Software comes with up to date and comprehensive user documentation, and we are recognised for our expertise and advice, responsive support and provision of on site training.

SeaGIS sells and supports the following software products.
  • CAL is photogrammetric camera calibration and bundle adjustment software, used for calibration of 3D vision measurement systems, and high precision photogrammetric measurement. Calibrations from the CAL software are used to enable 3D measurement in EventMeasure (Stereo) and StereoLib.

  • EventMeasure is software for logging and archiving events occuring in digital imagery, and for generating and reporting various abundance measures (MaxN, cumulative MaxN, Mean count). It is typically used for analysing fish surveys using either stationary (baited or unbaited), or transect imagery, but it is also used in a variety of biological and ecological applications. EventMeasure (Stereo) provides an all-in-one package for event logging and 3D measurement. EventMeasure (Stereo) requires calibration results from CAL to allow 3D measurement.

  • StereoLib is a C++/MFC extension dll that provides photogrammetric measurement functionality and allows developers to incorporate photogrammetric measurement into their own interfaces. The library provides a C++ and C interface allowing it to be used in Visual Basic and C# (.NET) applications. StereoLib requires calibration results from CAL.

  • TransectMeasure is software for the analysis of transects or biological sampling from images using random or pre-defined dot patterns. TransectMeasure supports calibration with known-sized objects, quadrats, lasers or stereo measurements (imported from EventMeasure), allowing scaled measurement of length and area from single images.

The following table summarises the differences between measurement with single and stereo camera systems:
