The invention discloses a lens group with a vehicle-mounted image distortion correction function and an electronic rearview mirror CMS. According to the lens group with the vehicle-mounted image distortion correction function, the ultra-thin distortionless lens is large in wide angle, ultra-thin, high in resolution and light, so that the defects in the prior art are overcome. The seven lenses adopted by the invention are all plastic free-form surface lenses, although the price is high and the preparation process is tedious, the distortion correction effect is better, and the product competitiveness is improved; by reasonably using the plastic free-form surface lens and limiting the focal power of each lens, the distortion of the wide-angle lens is effectively improved, the shooting effect is improved, and the defects in the prior art are overcome. According to the invention, the lens group with a vehicle-mounted image distortion correction function is applied to the CMS system, so that the imaging quality can be effectively improved, and stable and clear road condition real-time images are provided for a driver.

    本发明公开了具有车载图像畸变矫正功能的透镜组及电子后视镜CMS。本发明的具有车载图像畸变矫正功能的透镜组的超薄无畸变镜头,大广角、超薄、高分辨率、轻便的镜头,以克服现有技术中的不足之处。本发明采用的七个透镜均为塑胶自由曲面透镜,虽然其价格昂贵,制备工艺繁琐,但其矫正畸变效果较佳,提高了产品竞争力;通过合理的使用塑料自由曲面镜片及限定每个透镜的光焦度,有效的改善了广角镜头的畸变,提高了摄像的效果,克服现有技术中的不足之处。本发明将具有车载图像畸变矫正功能的透镜组运用在CMS系统中,能够有效的提升成像质量,为驾驶员提供稳定清晰的路况实时影像。
