Overview

The video capability in Vantor Raptor Sync provides georegistration of full motion video imagery. The core functionality is provided by a network server (the Raptor Sync server), started through the command-line (CLI) raptor_sync_server. Once started, the server serves clients with georegistrations over a request/response network protocol.

For convenience, a client application able to handle Mpeg TS video accompanied with MISB 0601 metadata is included in the video capability for Raptor Sync. The Raptor Sync client has the CLI raptor_sync_client.

Requirements for georegistration​

For successful georegistration the Raptor Sync server must be configured with one or several Vivid Terrain Surface Models (reference datasets). More than one reference dataset may be needed to geographically cover the entire track of a full motion video.

The required actions of a client to the Raptor Sync server are:

  • For each video frame send the video frame's raster data (image) to the server. Either in an uncompressed, single channel unsigned 8-bit raster format, or in PNG format.
  • For each image send accompanying camera metadata in terms of position, attitude and field of view for the image.
  • The accompanying metadata must be within the tolerances of the Raptor Sync server's search constraints towards the reference datasets. Please visit the product specification for details.

Figure of Merit​

Each georegistered video frame will have a Figure of Merit (FOM). The value is in the range [0.0…1.0] and describes the similarity between the video image and the reference dataset. A higher value indicates a higher similarity.
