SeaGIS does not just sell software. Our software products are built on more than 15 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 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.
- 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.
- StereoLib is a development library with a C and C++ interface. It provides photogrammetric measurement functionality and allows developers to incorporate photogrammetric measurement into their own interfaces. StereoLib requires stereo camera calibrations produced by CAL. This product is only required if you wish to write your own stereo measurement software - typically, if you are using EventMeasure you don't need StereoLib.
The following table summarises the differences between measurement with single and stereo camera systems:
