摘要:
Systems and methods for determining whether a region of interest (ROI) includes a runway are provided. One system includes a camera for capturing an image of the ROI, an analysis module for generating a binary large object (BLOB) of at least a portion of the ROI, and a synthetic vision system including a template of the runway. The system further includes a segmentation module for determining if the ROI includes the runway based on a comparison of the template and the BLOB. One method includes the steps of identifying a position for each corner on the BLOB and forming a polygon on the BLOB based on the position of each corner. The method further includes the step of determining that the BLOB represents the runway based on a comparison of the polygon and a template of the runway. Also provided are computer-readable mediums storing instructions for performing the above method.

A method of removing synthetic vision terrain and objects from a graphical display when unsafe to rely on the synthetic vision terrain and objects is provided. The method comprises receiving current position data from at least one sensor, determining when to fade out synthetic vision terrain and objects based on the position data received, and fading out synthetic vision terrain and objects gradually when determined.
摘要:
A system and method for fusing sensor data and synthetic data to form an integrated image are described. An image registration process is used to fuse the images. The image registration process is performed on gradients of a landmark image. The gradients are extracted from both sensor and synthetic datasets for the landmark image. Using the image gradient, a center of mass for each of the gradient's curves is calculated. By solving a minimization problem to reduce error, a desired transformation operator can be obtained to match the sensor image to the synthetic image.

Systems and methods for outputting instructions when a vehicle is not responding to a roll-angle alert. An example system includes one or more altitude sensors that determine one of altitude above ground level or barometric altitude, one or more roll-angle sensors that determine the roll-angle of the vehicle, and a processor. The processor receives the altitude and roll-angle information, determines if an excessive roll-angle condition exists based on the received altitude and roll-angle information, and generates a roll-angle alert signal if a roll-angle alert condition exists. The processor generates a roll-direction signal based upon vehicle position relative to the horizon and outputs the determined roll-direction signal via the one or more output devices, if one of the condition still exists after the time delay, the vehicle roll-angle has deteriorated away from the desired threshold, or the roll-angle rate is greater than a roll-angle rate threshold.

A system and method are provided for prioritizing incoming datalink messages. When a datalink message is received in an aircraft, it is parsed into individual information elements. The relevance of the received datalink message is then assessed from the individual information elements. The received datalink message is then categorized into one of a plurality of playback priority categories, based on the assessed relevance of the received datalink message.

Methods and apparatus are provided for automatically and adaptively configuring a system for a user. User data that includes information representative of temporal and contextual user preferences, behaviors, habits, biases, idiosyncrasies, and tendencies associated with system settings and configurations are loaded into the system. The system is then configured based on the user data. User-initiated operations of the system are continuously monitored to model user performance. The user data are continuously updated based on the modeled user performance, and the system is continuously and automatically reconfigured based on the updated user data.

A method for displaying attitude, heading, and navigation data on a single display is described. The method comprises configuring the display with terrain data, overlaying the terrain display with a compass rose display, and superimposing an attitude direction indicator with the compass rose display, the attitude direction indicator referenced to a center of the compass rose.
