Dynamic wake prediction and visualization with uncertainty analysis

A dynamic wake avoidance system utilizes aircraft and atmospheric parameters readily available in flight to model and predict airborne wake vortices in real time. A novel combination of algorithms allows for a relatively simple yet robust wake model to be constructed based on information extracted from a broadcast. The system predicts the location and movement of the wake based on the nominal wake model and correspondingly performs an uncertainty analysis on the wake model to determine a wake hazard zone (no fly zone), which comprises a plurality of “wake planes,” each moving independently from another. The system selectively adjusts dimensions of each wake plane to minimize spatial and temporal uncertainty, thereby ensuring that the actual wake is within the wake hazard zone. The predicted wake hazard zone is communicated in real time directly to a user via a realistic visual representation. In an example, the wake hazard zone is visualized on a 3-D flight deck display to enable a pilot to visualize or “see” a neighboring aircraft as well as its wake. The system substantially enhances the pilot's situational awareness and allows for a further safe decrease in spacing, which could alleviate airport and airspace congestion.

The invention discloses a scanning laser based large-scale three-dimensional terrain modeling method. The scanning laser based large-scale three-dimensional terrain modeling method comprises the following steps of: firstly perceiving a surrounding environment through the scanning laser arranged on a mobile robot platform, and transforming original laser data into three-dimensional point clouds through coordinate transformation; secondly preprocessing the three-dimensional point clouds by adopting a median filter method, and constructing an octree structure to complete data storage; then carrying out fusion processing on data by adopting a Gaussian mixed model based randomization method to build a terrain environment model in real time; and finally detecting and processing an obstructed area positioned in the terrain environment model to further enhance model accuracy. In the invention, the problem of real-time modeling of a large-scale complex terrain is effectively solved by adopting the low-cost two-dimensional scanning laser; and good balance between the model accuracy and real-time property is realized in such a way that randomization processing is carried out on various uncertainties of the terrain environment model, and therefore, wide requirements of different fields, such as a GIS (Geographic Information System) system or unmanned autonomous navigation and the like, can be met.
