4. MATISSE SOFTWARE®<br />
4.1. General architecture<br />
The MATISSE Software® [ALL04] has been developed to integrate all the algorithms of georeferenced<br />
<strong>mosaic</strong>ing. It is flexible and can be used with many underwater vehicles as soon<br />
as they are equipped with a down-facing camera and a continuous navigation system (deadreckoning<br />
navigation).<br />
In Figure 6, the diagram represents the condition of use of MATISSE Software® with a ROV.<br />
The video stream and the navigation data are transferred up to the surface via the umbilical<br />
tether. They are processed in-line to produce geo-referenced <strong>mosaic</strong>s. An option consists of<br />
recording the video stream on a video DVD and the navigation data as messages on a CD.<br />
Playing back video and navigation data together makes possible off-line <strong>mosaic</strong> <strong>building</strong>.<br />
