Embodiment 1

[0038] Embodiment 1: A kind of method that adopts visual tracking device to evaluate pilot's vision distribution, this method comprises the following steps:

[0039] Step 1: Divide the flight mission into several typical stages, and conduct a weight survey on multiple pilots by setting the weight questionnaire, set the weight value of each typical stage for the success of the entire mission, and set up two stages of information search and information processing weight ratio.

[0040] Specifically, first select 10 outstanding pilots to conduct a questionnaire survey. The take-off and landing tasks are divided into five different typical stages, including five stages of take-off, one turn, three sides, two turns and landing, and the weights of these five stages to successful landing are scored. The scoring criteria are as follows: 1 point is not important, 2 points are somewhat important, 3 points are moderately important, 4 points are very important, and 5 points are very impo...

Abstract

The invention discloses a method for evaluating visual distribution of a pilot by adopting visual tracking equipment. The method is established based on an eye movement measurement index (glancing track length) in a search process and an eye movement index (fixation time percentage/fixation number percentage) in a processing process. The method comprises the following steps: firstly, decomposing a flight mission into a plurality of typical stages, and then, confirming weight degrees of an attention search process and an attention information processing process and the weight of each typical stage through subjective questionnaire survey; and then, collecting eye movement data of both eyes of a tested pilot and an excellent pilot through SMI glasses type visual tracking equipment, recording an experimental scene in real time through a scene video recorder, playing back a scene video to obtain attention interest areas and sight change data of the tested pilot and the excellent pilot, carrying out data analysis and calculation to obtain correlation between the eye movement data of the tested flight trainee and the excellent pilot, and finally presenting an evaluation grade of attention distribution of the tested pilot.

Description

technical field [0001] The invention relates to a method for evaluating a pilot's visual distribution by using a visual tracking device, and belongs to the field of aviation ergonomics. Background technique [0002] Attention allocation indirectly reflects the state of the pilot's cognitive psychology. The research on attention distribution by scholars at home and abroad began in the 1950s. Fitts et al. began to study the measurement of pilots' attention distribution behavior, and the results established the classic T-shaped instrument layout. Subsequently, a large number of researches at home and abroad have shown that the study of the mechanism of pilots' attention distribution and its application is of great significance for ensuring flight safety, reducing human errors, and optimizing the cockpit interface. This importance is particularly prominent as aircraft become more intelligent and complex. [0003] So far, the methods of studying attention allocation mainly incl...
