Abstract

The present invention provides a radar dynamic target calibration method and system based on eye movement tracking, including: acquiring real-time geographic coordinate data and screen coordinate data of the aircraft in the radar interface; acquiring eye movement fixation point data, and calibrating the static fixation point in the radar interface Area: establishing a conversion model between geographic coordinates and screen coordinates, and marking the dynamic target area according to the conversion model. The invention monitors the physiological parameters of the controller's eyes in real time, fits the eye measurement data with the real-time position information of the aircraft, calibrates the dynamic target in the radar screen, and distinguishes the controller's attention to the allocation of resources, thereby improving the timeliness and reliability of aircraft command and deployment. reliability.

Description

technical field [0001] The invention relates to the field of air traffic control, in particular to a radar dynamic target marking method and system based on eye movement tracking. Background technique [0002] As an important position in the air traffic management system, the controller plays a vital role in the reliability, safety and efficiency of the aircraft. With the rapid development of air transport, the number of aircraft in the airspace has increased sharply, forming a complex airspace environment. The work pressure and workload of air traffic controllers are increasing day by day. The range of gaze transfer of controllers will be reduced due to the increase in the complexity of the airspace environment. It is very likely that gaze transfer and search information will only be performed between some aircraft, thereby improving attention resources. Unreasonable distribution. Therefore, it is of great practical significance to accurately identify and extract the spec...
