Info

All the geo-referenced mosaics are stored on-line in a hierarchical file structure: cruise/dive/session/treatment. One mosaic represents the smallest unit consisting of 500 merged images collected within each half a minute during the mosaicking process. It covers an area about 3 m x 6-7 m. And in this case one treatment consists of up to about 20 mosaics which equals an area of about 3 m x 100 m (Figure B5.4-1 and B5.4-2). 2,5 - 3 m one mosaic = 6,5 m Fig. B5.4-1: This part of a treatment shows the construction of the images within the muddy region (thermal centre) of the HMMV. 20 m Fig. B5.4-2: Changing areas of tube worms and bacterial mats within a 20 m stripe in the north west of the thermal centre of HMMV. 20 m Fig. B5.4-3: Rough topography effects of pixel sizes during the real time video mosaicking. - 217 -
The quality of the mosaics depends on several conditions including different lightings (differences are easily to recognize comparing figures B5.4-1 and B5.4-2) as well as the varieties of pixel sizes (when the camera had to record a rough topography) (figure B5.4-3). The geo-referenced mosaics can be visualized and queried stationtemporally within a geographical information system (GIS) and together with other collected data it will be possible to receive a multidisciplinary view of HMMV. Results Video mosaicking was conducted during six of the seven dives of "Victor 6000". Finally data were collected for 51.5 hours – this equals about 37 km stripes 3 meter wide and covering an area of 0.111 km² (Table B5.4-1).
