Head-up display picture compatibility evaluation method for military laser protective lens

The invention discloses a head-up display picture compatibility evaluation method of a military laser protective lens. The method comprises the following steps: measuring a maximum brightness value and a frequency spectrum curve of a head-up display picture in a cabin; measuring a transmittance curve of the required laser protective lens; calculating a head-up display transmission coefficient TR lens of the laser protective lens according to the frequency spectrum curve of a head-up display and the transmittance curve of the laser protective lens; according to the maximum brightness value of the head-up display picture in the cabin, calculating a head-up display transmission coefficient TR index of the laser protective lens required by the head-up display which can be seen clearly by human eyes under a high-altitude light facing condition; and comparing the calculated head-up display transmission coefficient TR lens of the laser protective lens with a head-up display transmission coefficient TR index required
