The logic device is configured to render a first perspective of a three dimensional representation of the volume data on a display of the user interface, determine a first viewpoint vector within the 3D representation based, at least in part, on a first user input received by the user interface; and identify an object or position within the volume data based, at least in part, on the first viewpoint vector and the first user input.
G06F 3/0481 - Interaction techniques based on graphical user interfaces [GUI] based on specific properties of the displayed interaction object or a metaphor-based environment, e.g. interaction with desktop elements like windows or icons, or assisted by a cursor's changing behaviour or appearance
G06F 3/0484 - Interaction techniques based on graphical user interfaces [GUI] for the control of specific functions or operations, e.g. selecting or manipulating an object, an image or a displayed text element, setting a parameter value or selecting a range
G06F 3/0488 - Interaction techniques based on graphical user interfaces [GUI] using specific features provided by the input device, e.g. functions controlled by the rotation of a mouse with dual sensing arrangements, or of the nature of the input device, e.g. tap gestures based on pressure sensed by a digitiser using a touch-screen or digitiser, e.g. input of commands through traced gestures
G06F 3/01 - Input arrangements or combined input and output arrangements for interaction between user and computer
G06T 19/20 - Editing of 3D images, e.g. changing shapes or colours, aligning objects or positioning parts
G01S 15/96 - Sonar systems specially adapted for specific applications for locating fish
Techniques are disclosed for systems and methods to provide three dimensional volume rendering of volume data for use when operating mobile structures. A three dimensional volume rendering system includes a logic device configured to communicate with a user interface and receive volume data from a volume data source. The logic device is configured to render a three dimensional) representation of the volume data on a display of the user interface according to a view perspective, render an indicator key on a first two dimensional plane overlaid in the 3D representation, detect a change condition, and rotate the indicator key about a rotational axis in response to the detected change condition.
Techniques are disclosed for systems and methods for labeling objects displayed by an augmented reality display system used to assist in the operation of mobile structures. Such an augmented reality display system includes a logic device configured to communicate with navigational sensors and imaging modules coupled to a mobile structure, where the navigational sensors are configured to provide navigational data associated with the mobile structure and the imaging module is configured to image a scene from a position on the mobile structure. The logic device is configured to detect an object in the scene, determine a heading reliability associated with the detected object based, at least in part, on the navigational data, and render an integrated model of the scene on a display, where the integrated model is configured to indicate the determined heading reliability associated with the detected object.

UNMANNED AERIAL SYSTEM ASSISTED NAVIGATIONAL SYSTEMS AND METHODS
Flight based infrared imaging systems and related techniques, and in particular unmanned aerial system (UAS) based systems, are provided for aiding in operation and/or piloting of a mobile structure. Such systems and techniques may include determining environmental conditions around the mobile structure with, at least, the UAS, detecting the presence of objects and/or persons around the mobile structure, and/or determining the presence of other structures around the mobile structure. Instructions for the operation of such mobile structures may then be accordingly determined responsive to such data.
