Abstract

The invention provides a radar dynamic target calibration method and system based on eye-movement tracking. The radar dynamic target calibration method comprises the steps that real-time geographicalcoordinate data of an aircraft and screen coordinate data in a radar interface are obtained; eye-movement fixation point data are obtained, and a fixation point static area is calibrated in the radarinterface; and a geographical coordinate and screen coordinate conversion model is established, and a dynamic target area is calibrated according to the conversion model. Eye physiological parametersof a controller are monitored in real time, eye measuring data are fitted with real-time position information of the aircraft, a dynamic target in a radar screen is calibrated, distribution of controller attention resources is identified, and the timeliness and reliability of commanding and deploying the aircraft are improved.

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...
