Abstract
A display device for controlling a remotely controlled camera is disclosed. The display device comprising an image receiver configured to receive an image of the image stream from the camera, and a processor. The processor including a retriever configured to retrieve a selected buffered image corresponding to a data insufficiency region within a target field of view while adjusting the camera from a current field of view to the target field of view until the image stream from the camera includes the insufficiency region being depicted within the target field of view and a depicter configured to depict the selected buffered image on the display device at least in the insufficiency region.
Claims19
A display device for controlling a remotely controlled camera, the display device comprising:
- an image buffer memory;
- and
- a processor including:
- an image receiver configured to receive an image of an image stream from the camera;
- a chart engine configured to integrate the image stream into a 3-D virtual representation of a marine environment based upon a geo-positional location of the camera and a field of view of the camera;
- a capture module configured to buffer portions of the image stream as buffered images in the image buffer memory, each of the buffered images being associated with a corresponding field of view of the camera;
- a command sender configured to adjust the camera from a current field of view to a target field of view;
- a retriever configured to retrieve at least a portion of a selected buffered image, upon determining during the adjustment that a lag exists between an actual field of view of the camera and the target field of view which would result in a data insufficiency region within the target field of view for which there is no current image stream data from the camera to be displayed on the display device;
- and
- a depicter module configured to depict the selected buffered image on a display of the display device at least in the data insufficiency region.
A method for control of a remotely controlled camera in a marine environment, the method comprising:
- receiving an image stream from the camera;
- integrating the image stream into a chart engine, the chart engine providing a 3-D virtual representation of the marine environment based upon a geo-positional location of the camera and a field of view of the camera;
- buffering portions of the image stream as buffered images in memory, each of the buffered images being associated with a corresponding field of view of the camera;
- sending a command to adjust the camera from a current camera field of view to a target field of view;
- determining during the adjustment that a lag exists between an actual field of view of the camera and the target field of view which would result in a data insufficiency region within the target field of view for which there is no current image stream data from the camera to be displayed on the display device;
- upon determining that a lag exists, retrieving at least a portion of a selected buffered image;
- and
- depicting the portion of the selected buffered image on the display device at least in the insufficiency region.
A system for control of a remotely controlled marine camera, the system comprising:
- a display device;
- a remotely controlled marine camera mounted to a superstructure element of a marine vessel configured to capture an image stream of a field of view and being adjustable to pan and optically zoom in or out;
- a computing device configured to:
- receive the image stream and buffer portions of the image stream as buffered images in memory, each of the buffered images being associated with a corresponding field of view of the camera;
- integrate the image stream into a chart engine, the chart engine providing a 3-D virtual representation of the environment based upon a geo-positional location of the marine vessel and a field of view of the camera;
- send a command to adjust the camera from a current camera field of view to a target field of view;
- determine during the adjustment that a lag exists between an actual field of view of the camera and the target field of view which would result in a data insufficiency region within the target field of view for which there is no current image stream data from the camera to be displayed on the display device;
- and
- upon making such determination:
- retrieve at least a portion of a selected buffered image;
- and
- depict the portion of the selected buffered image on the display device at least in the insufficiency region.
