s2, selecting a lens group, wherein in a small-sized sedan or cross-country vehicle with an A pillar provided with an airbag, the total mass of the lens group is less than 400g, as the first reflector 1 is further away from the A pillar, the A pillar decorative plate has smaller protection effect on the A pillar decorative plate, the A pillar airbag is inflated instantly to have larger influence on the first reflector, the mass of the A pillar airbag is safer at about 50 g, the lightweight index of the lens group in other vehicles such as heavy trucks can be adjusted according to the safety requirement of the vehicle, the thickness of a solid layer is 0.01-3mm, the light transmittance is 0-90%, the light reflectivity is 10-100%, the lens group is prevented from being broken, and extra high-strength fibers can be added to reinforce the lens group;
s3, the lens group can be installed in a vehicle with an airbag, two mirror surfaces are selected to be opposite and keep a certain distance, the two mirror surfaces are approximately parallel, the light-weight first reflecting mirror 1 and the second reflecting mirror 2 with the two mirror surfaces in a translational staggered mode form the lens group, then the lens group is installed on a column A or a windshield in the vehicle by utilizing the height-adjustable adjusting support 51 and the quick-release interface 52, or is installed on the column A or the windshield in the vehicle by utilizing a sucking disc, a magnetic sticker and a magic sticker;
s4, imaging by the lens group, and observing a reflected image of a scene with a blind area far away on the second reflector 2 of the lens group, wherein the reflected image on the second reflector 2 is matched with an even reflected image of 2.4.6.8 … … (n-2) n and the like of the reflected image of the first reflector 1;
