The invention has the advantages that: a kind of no thermalization day and night high definition on-vehicle lens being designed to according to above scheme, can
Target in 50-200 meters of distances is identified, is used cooperatively with other wide-angle on-vehicle lens, trailer-mounted radar, automobile pair is improved
The recognition capability of distant object.High resolution of the present invention, thermal stability is good, translucency is good, day and night confocal, can effectively identify
Distant object, in advance provides alert to the target of vehicle front, provides traffic information for control loop, in addition, the vehicle-mounted mirror
Head system is compact-sized, and shockproof effect is good, is highly suitable for vehicle-mounted pick-up head system.
