Aiming at two dynamic simulation flight tasks with or without information enhancement, a pilot completes the flight tasks according to the indication of a display and AR glasses, in the execution process of the flight tasks, experimental result data of the flight tasks of the pilot are recorded through an information processing module, finally, the experimental task data under the two conditions with or without information enhancement are compared and analyzed, and whether the difference of the two sets of data has statistical significance is compared, so that the AR augmented reality effect is deduced.
The system is based on a dynamic simulated flight task, under the two conditions of task information presence and absence of augmented reality display, a large sample pilot completes actual operation, objective simulated task performance data is obtained, and the effect of information enhancement on the simulated flight task is contrasted and analyzed.
In a further scheme, the dynamic simulation flight task comprises a plurality of pilots with flight experience, and all the pilots are divided into a group A and a group B to be tested as experimental objects; the group A is tried out before the dynamic simulation flight task without information enhancement is completed, and then the dynamic simulation flight task with information enhancement is completed; the B group is tried out before the dynamic simulation flight task with information enhancement is completed, and then the dynamic simulation flight task without information enhancement is completed. Each pilot group has similar experience, is randomly divided into a group A and a group B, and then carries out respective dynamic simulation flight tasks. Specifically, the group A firstly carries out a dynamic simulation flight task without information enhancement, and when the flight task is started, a pilot flies according to the prompt of information displayed by a display. Experimental data can be obtained for a pilot to perform a flight mission by looking only at the display. And the experimental data in the flight process is recorded by the information processing module for subsequent comparative analysis. Then, a dynamic simulation flight task with information enhancement is carried out, when a pilot watches the display to fly, the AR glasses also provide information with enhancement effect for the pilot, and the information processing module records corresponding experimental data. And finally, carrying out comparative analysis on experimental data with information enhancement and experimental data without information enhancement so as to deduce the AR augmented reality effect.
Further, the pilot may be configured to perform simulated flight tasks according to the display screen and/or the prompt of the AR display information, respectively, not limited to: take-off, ascent, cruise, ground target search, air-to-ground assault, return voyage, and landing. Starting the system, and leading a pilot to explain the purpose of the experiment, the experiment task and the attention to the pilot; pilot logs in system and fills in basic information; simulating task practice, wherein each pilot firstly practices the simulating task to enable the pilot to be familiar with a basic experiment task flow, an experiment method and attention points; and then performing formal experiments, taking off normally, keeping the speed increasing in a rising state, prompting according to display instructions or instructions of AR glasses, displaying information according to display pictures and/or AR, cruising, searching ground targets, locking the targets, and shooting according to the instructions.

And finally, performing comparative analysis on the experimental task data of all the tested objects under the two conditions of information enhancement and information enhancement, and comparing whether the difference of the two groups of data has statistical significance or not so as to infer the AR augmented reality effect.
The enhanced information comprises information of each waypoint, ground target information and runway information of a landing airport when a pilot navigates in a simulated flight task. These enhancement information all can show and indicate through AR glasses, and the pilot alright direct perception in the simulation flight task, if the information enhancement that provides in the AR glasses is effectual, that pilot just can be better accomplish the flight task, and the experimental achievement data can be better, so also can conclude that AR augmented reality's effect is good this moment. If the information provided in the AR glasses is poor in enhancement effect or fails, the information has no statistical significance with experimental data of the flight mission without the enhancement information, and therefore the AR enhancement reality effect is not good at the moment.

If the image detection model can accurately detect the parameters in real time and can display the parameters in the AR glasses, the pilot can acquire the parameter information and can be more accurate in the flight task process, such as the process of assaulting a ground target. If the finally obtained experimental data show that the target is not hit, or the experimental data have no statistical significance with the experimental data of the pilot in the flight mission without information enhancement, the AR augmented reality effect is not good.
