Synched video ground truth
Eonfusion's ability to fuse media with vector data is used here to synchronize video data with a 4D (x, y, z, time) track. The track is displayed in an Eonfusion scene along with bathymetry that has habitat information overlaid. By querying the track using an Eonfusion "value probe" tool, the video is synchronized in time with the probed position on the track This enables the user to quickly and easily ground-truth their video data by providing a seamless and visually powerful link between the position of the video camera in space and the corresponding video frames.
Eonfusion also allows the user to manually attribute sections of the track according to what is observed in the video, so that the user's interpretation becomes a permanent part of the data. There is also the ability to copy attributes to the track from the other vector and raster data in the scene. These capabilities together mean that the user can import a simple 4D track and re-export it after processing with any number of new attributes - both user-generated and fused from other data sources.
