[0049] As an optional implementation, in this embodiment, the pilot needs to undergo a lot of training before performing the flight task, and the infrared vision training is an indispensable training, in which the following are applied:

[0050] The infrared imaging unit is an infrared camera in the prior art, the model of which is DS-2CD2347G1-L, the maximum resolution of which is 2688x 1520 pixels, and the minimum resolution of which is 640x 480 pixels.

[0051] The display unit is a portable display in the prior art, the model of which is ZenScreen Go MB16AP, and the size of which is 24-14 inches.

[0052] The data processing unit is a host in the prior art, which is equipped with a GPU, the model of which is NVIDIA Tesla. When the pilot A is training in the training cabin, the timer is first installed through the mounting structure, the timer is turned on at the beginning of the training, the timer counts the training time of the pilot, the infrared camera trains the simulated scene inside the infrared camera training room, the resolution of the infrared camera DS-2CD2347G1-L is 2688x 1520 pixels, the infrared camera transmits data to the host, the GPU processes the infrared image data, and transmits the processed data to the portable display, the size of the portable display is 14 inches, therefore, the R actual = 145.5, wherein R max = 192 (2688 / 14), R min = 63 (1520 / 24), after substituting into the formula for calculating the infrared image clarity I,

[0053] The infrared image definition is calculated as 0.88, and the environmental complexity C is calculated. In the training field, the maximum number of obstacles actually prepared is 20, and the number of obstacles actually present in this training is 5. After substituting the formula, the environmental complexity is 0.25 on a sunny day, and the environmental complexity is 1.25 on a rainy or foggy day; when pilot A finishes training, stop timing the timer, and the training time of this time is 1200s, so the training time D = 0.2(20min); the theoretical maximum value of the reaction time of human reaction to things is 0.3s, and the theoretical minimum value of the reaction time is 0.1s. In the past training, since the data of each training will be recorded, the average reaction time of pilot A is 0.22s, so through the above calculation formula of pilot ability reaction index, it can be known that the pilot ability reaction index of pilot A is 0.4, and the training load T is the difficulty coefficient of training, the index is 1-5, the training coefficient of this time is 2, and finally the external factor Q needs to be obtained. The influence of external factors is 1-5, including: poor sleep quality, illness, continuous training frequency more than 10 times, training total frequency not more than 10 times and intense exercise, each accounting for 1, the maximum influence score is 5, pilot A played 3 hours of badminton the night before, the total training frequency is not more than 10 times, and there is no continuous training for 10 times, the body condition is good, and the sleep quality is good. Under the condition of good sleep quality, the influence score P of external factors on training is 2, which is 5, so the external factor Q is calculated by the above formula as 0.4; finally, after obtaining all the data, it is calculated that on a sunny day:

[0054]

[0055] Therefore, the training effect index E of pilot A is 0.66;

[0056] In the next training, pilot A training cabin training, first through the installation structure on the timer installation, training began, open timer, timer on the pilot training time, there are equipment inconvenience, therefore, the infrared image clarity = 0.88, then on the environmental complexity on C calculation, in the training field, the actual preparation set the maximum number of obstacles is 20, in this training, the actual number of obstacles is 5, after the formula, in sunny day, the environmental complexity is 0.25, when pilot A ends training, stop on the timer, the training time is 1200s, therefore, training time D = 0.2(20min);Human reaction to things in the reaction time of the theoretical maximum value is 0.3s, the theoretical minimum value of reaction time is 0.1s, in the past training, because each training data will be recorded, pilot A's average reaction time is improved to 0.22s, therefore, through the above calculation formula of pilot ability reaction index, pilot A's pilot ability reaction index is 0.4, and training load T is training difficulty coefficient identification, index is 1-5, this training alone coefficient is 3, finally still need to get external factors Q, pilot A in the previous night and did not have strenuous exercise, training total number of times more than 10 times, and did not have continuous training 10 times, occasionally feel cold, sleep quality is poor, external factors on the training of influence score P is 3, for 5, therefore, external factors Q after the above formula calculation is 0.6;Finally, after obtaining all the data, sunny day:

[0057]

[0058] Therefore, the training effect index E of pilot A = 0.62;

[0059] Using the above method, using the control variable method, changing the value of only one parameter each time, constantly training, finally can be calculated by the training effect index E comparison, see which factor has the greatest influence on the training effect index E of pilot, find out the most critical factor affecting the flight of the pilot, finally in the flight task, avoid the factor, so that the pilot can perform the flight task better.
